STORY HIGHLIGHTS
Japan closed down its last operating nuclear reactor on Saturday
Final shutdown follows a swing against nuclear energy after the Fukushima meltdowns last year
Thousands marched through Tokyo Saturday to celebrate the final closure
Government has warned that summer energy demand may prompt rolling blackouts
.
.
Tokyo (CNN) -- As Japan began its workweek Monday morning, the trains ran exactly on time, the elevators in thousands of Tokyo high rises efficiently moved between floors, and the lights turned on across cities with nary a glitch.
What makes this Monday so remarkable is that for the first time in four decades, none of the energy on this working day is derived from a nuclear reactor.
Over the weekend, Japan's last remaining nuclear reactor shut down for regular maintenance. In the wake of the Fukushima nuclear disaster, reactors have not been allowed back on. Japan is now the first major economy to see the modern era without nuclear power.
Tomari Nuclear Power Plant's reactor 3 in Hokkaido shut down Saturday evening in a much-watched move by government, industry and environmentalists, who are waged in a public battle over the future of Japan's energy policy.
"I think it is not easy, but this challenge is worth fighting for," said Greenpeace Japan's Junichi Shimizu. "There is an increased chance of earthquakes in Japan, so that has a significant risk to the Japanese people and the Japanese economy. The only way forward is to rapidly shift the energy source from nuclear to other sources of energy."
That's not the call just from environmental activists, but from a public suspicious of nuclear energy and its regulatory bodies since a tsunami and earthquake triggered nuclear meltdowns at three reactors at the Fukushima Daiichi nuclear plant in March 2011.
Thousands marched through the streets of Tokyo on Saturday, celebrating the shutdown of the final reactor.
The protesters waved colorful, traditional "koinobori" carp-shaped banners for Children's Day that became a symbol of the anti-nuclear movement.
That movement grew from the grassroots level in the wake of the disaster, as the country watched tens of thousands of residents living within a 20-kilometer (12-mile) radius of the nuclear plant evacuated and the area remaining turn into a contaminated wasteland.
Prior to the Fukushima disaster, Japan relied on nuclear for approximately 30% of its energy. As reactors have come off-line, the country has increased its imports of fossil fuels.
Japan's government predicts it won't be able to keep up that pace, and the void will result in an energy crunch this summer, possibly leading to rolling blackouts.
The national government's ruling party, the Democratic Party of Japan, has been urging local communities to allow reactors to return to operation.
The DPJ's deputy policy chief, Yoshito Sengoku, bluntly said without nuclear energy the world's third largest economy would suffer. "We must think ahead to the impact on Japan's economy and people's lives, if all nuclear reactors are stopped. Japan could, in some sense, be committing mass suicide," said Sengoku.
Hiromasa Yonekura, chairman of Japan's biggest business lobby, Keidanren, joined the plea in an April press conference. "We cannot possibly agree to do the kind of energy saving yet again this year, or every year from now on," he said, referring to the country's efforts to turn off air conditioners and shift operation of production lines to weekends. "The government must bring the nuclear power stations back into operation."
Economist Jesper Koll, managing director at JP Morgan, says Japan could avoid the economic fallout by defining a clear energy policy, something it has failed to do so far.
"The issue to the private sector of Japan is the government is taking its time in a very emotional, highly politicized debate. And the end result is very, very slow or no decision making at all. After all, if you don't have an energy policy, you don' really have an economic policy because everything revolves around the energy," he said.
Japan's prime minister has promised a clear energy policy sometime this year, perhaps this summer.
But Yukie Osaki, who used to live in Fukushima, says she won't accept any policy that includes nuclear energy. "Nobody believes the government anymore when it says nuclear plants are safe," she said.
"Japan is an earthquake country. It is already dangerous to have nuclear plants here. If we have another accident, we won't have anywhere to live in Japan anymore."

Diablo Canyon nuclear plant in California knocked offline by jellyfish-like creatures called salp

This photo provided by the Diablo Canyon Power Plant on Friday shows salp, a gelatinous sea creature, at a nuclear reactor intake structure.

By James Eng, msnbc.com
.
In Japan, it was a monstrous earthquake and tsunami that brought down the Fukushima nuclear plant. In California, it’s a tiny, jellyfish-like sea creature called salp that’s causing problems at the Diablo Canyon atomic plant.
An invasion of salp has prompted Pacific Gas and Electric Co. to temporarily shut down a nuclear reactor at Diablo Canyon, in Avila Beach, San Luisa Obispo County, on the central California coast.
A giant swarm of the transluscent barrel-shaped organisms this week clogged intake screens that are used to keep marine life out of the seawater that is used as a coolant for the nuclear plant.
On Wednesday, PG&E officials reduced power output at the Unit 2 reactor, then decided to shut it down altogether “until conditions improve at the intake structure.” The plant’s other reactor, Unit 1, had already been shut down earlier in the week for a planned refueling and maintenance outage.
“Safety being the number one priority, there was such an influx of salp and you need ocean water to cool the reactors,” PG&E spokesman Tom Cuddy told msnbc.com on Friday. “At that point we made a conservative decision to safely shut down the unit.”
PG&E owns and operates the Diablo Canyon Power Plant, whose two reactors together produce approximately 2,300 net megawatts of electricity – enough to serve nearly 3 million northern and central California homes.
Cuddy said he wasn’t sure when the Unit 1 reactor would come back online.
“We’ll turn the unit on to full power when it’s safe to do so – when the salps leave,” he said. “The bottom line is we’re taking a methodical and conservative approach.”
Lara Uselding, a spokeswoman for the Nuclear Regulatory Commission, the federal agency that oversees reactor safety and security, said the plant is not in any danger.
“It’s not a normal operation condition, but the plant is safe and all the systems operated as designed,” she said.
Salps are tiny, gelatinous organisms that move by contracting, thus pumping water throughout their bodies. They can reproduce and multiply quickly.
Though salps look a bit like jellyfish, they are actually more closely related to organisms that have backbones. They typically grow to 1 or 2 inches long and usually do not appear at the coast, says Larry Madin, a salp expert and research director at Woods Hole Oceanographic Institution in Massachusetts.
“They’re typically more of an offshore living organism," Madin says. He surmises that the swarm at Diablo may have been carried in on currents blown by wind.
Other than clogging the cooling system filters of a nuclear plant, the organisms pose no danger, says Bruce Robison, senior scientist at the Monterey Bay Aquarium Research Institute in Moss Landing, Calif. They don’t sting, they don’t have teeth and they’re not poisonous.
Salps passively feed off tiny organic particles in the water and can reproduce sexually or asexually. “They can have their population size expand tremendously within a short period of time, which makes them very abundant. In a small space, they can take up all the space,” Robison says.
Madin said the slimy swarm at Diablo would probably go away in a few days, carried off by currents. Or, says Robison, they’ll quickly die off when their food supply runs out.
So the best bet, experts say, is for nuclear officials to just wait it out.
Despite the outage, California is not expected to experience any electricity shortages because it has ample reserves, said Stephanie McCorkle, spokeswoman California ISO, which operates the state's power grid and wholesale markets.
It’s not the first time that sea creatures have interfered with nuclear plant activity.
In 2008, a swarm of jellyfish led to a sharp decrease in power generation at Diablo Canyon, according to the Los Angeles Times. Similar jellyfish problems have cropped up at nuclear plants in the U.S., Japan, Israel and Scotland over the years, the newspaper said.
“It happens. It’s something you would expect along the coast,” Uselding said.
But Madin said this is the first time he’s heard of salps interfering with the operation of a nuclear plant.

STORY HIGHLIGHTS
The San Onofre nuclear plant has been shut down since radioactive gas escaped
Officials have said there's no harm to the public health, but can't identify the cause
The head of the NRC says the plant won't restart until a cause and plan is put forward
.
.
(CNN) -- A large Southern California nuclear plant is out of commission indefinitely, and will remain so until there is an understanding of what caused problems at two of its generators and an effective plan to address the issues, the nation's top nuclear regulator said Friday.
Gregory Jaczko, chairman of the U.S. Nuclear Regulatory Commission, refused to give a timetable as to when the San Onofre nuclear plant could resume operation. He said only that his agency had "set some firm conditions" as to when that could happen.
"We won't make a decision (to approve the facility's restart) unless we're satisfied that public health and safety will be protected," Jaczko told reporters. "They have to demonstrate to us that they understand the causes, and ... that they have a plan to address them."
The power plant has been shut down since this winter, when a small amount of radioactive gas escaped from a steam generator during a water leak. At the time, federal regulators said there was no threat to public health, though they could not identify how much gas leaked or exactly why it had happened.
The water leak occurred in thousands of tubes that carry heated water from the reactor core through the plant's steam generators.
Leaks occur periodically in older units, but plant owner Southern California Edison replaced the four steam generators at San Onofre in 2010 and 2011 as part of a $680 million project. They are in units 2 and 3 of the nuclear facility; unit 1 went out of service in 1992.
Each of the 65-foot-tall, 640-ton generators -- built by Japan's Mitsubishi Heavy Industries -- are packed with thousands of narrow tubes that carry hot, pressurized water from the reactors. The heat produces steam in a separate loop that drives the plant's turbines and generators.
"Tubes are vibrating and rubbing against adjacent tubes and against support structures inside the steam generators," the agency noted.
Eight of the more than 9,700 tubes in one of the unit 3 generators failed a pressure test, while six tubes in unit 2's reactor needed to be plugged, the NRC has found. Another 186 tubes in unit 2, which was shut down for refueling at the time of the leak, were plugged "as a precautionary measure."
In addition to driving the turbines to create electricity, the steam generators are "one of the barriers between the radioactive material in the reactor core and ultimately the external environment," Jaczko noted.
Located near San Clemente, the San Onofre nuclear plant's twin reactors are "Southern California's largest and most reliable sources of electricity," according to Southern California Edison's website. When operational, the facility -- which is owned by that utility, San Diego Gas and Electric, and the city of Riverside -- supplies power for 1.4 million households at any given time.

A federal inspection team is beginning its examination of steam generator tubes at the San Onofre nuclear power plant. One of those tubes leaked in January, prompting a reactor shutdown, and more tubes failed during a series of tests last week. Antonio Castelan reports.
An inspection team from the Nuclear Regulatory Commission began investigating faulty steam generator tubes at the San Onofre nuclear power plant Monday.
A series of failed tests last week involving steam generator tubes that are a key part of the plant's two reactors prompted the regulatory commission to send in a team of experts to find out why the vital energy source was failing.
The team plans to spend at least five days at the SoCal plant operated by Southern California Edison.
The trouble began in late January, when a tube in one of the reactors leaked.
That reactor was shut down, but not before a small amount of radioactive gas may have escaped into the atmosphere. Edison said neither plant employees nor the public was at risk.
Still, initial tests found that hundreds of steam generator tubes were showing signs of premature wear.
"We're seeing an unusual amount of wear in relatively new steam generators and, yes, that's unusual," said Victor Dricks with the Nuclear Regulatory Commission.
The problems at San Onofre have residents in nearby San Clemente worried.
"This is a huge amount of risk for us to be living so close to," said resident Patty Davis. "It's a big concern."
The federal inspectors will be looking at the design and construction of the plant's steam generators, as well as their transport from Japan where they were manufactured.
Each reactor contains thousands of steam generator tubes. San Onofre's second reactor is also shut down right now for routine maintenance.

STORY HIGHLIGHTS
The NRC cites the Palisades plant in Michigan for three safety violations
A plant spokesman says plant officials are cooperating fully with the NRC
The NRC says there will be additional inspections and greater oversight at the plant
.
WASHINGTON (CNN) -- A nuclear power plant in Covert, Michigan, has been cited for three safety violations, according to the U.S. Nuclear Regulatory Commission, joining two other U.S. nuclear plants in getting extra scrutiny from inspectors.
The worst of the violations stems from a September 25, 2011, incident at the Palisades Power Plant in which half of the control room indicators were lost because of an electrical fault "caused by personnel at the site," the NRC announced in a news release.
The NRC said it conducted a special inspection and "determined the plant failed to have adequate work procedures for the electrical panel maintenance work to ensure the job was done successfully."
The NRC said two other violations at Palisades were for a "low to moderate safety significance" issue related to a "coupling failure in the service water system." It said one of the service pumps failed last August due to cracking, something that also happened in 2009.
An inspection concluded: "The plant failed to prevent recurrence of the cracking condition and failed to completely consider the properties of the steel used in a past modification of the couplings."
The agency stated all three violations would result in additional NRC inspections and greater oversight of the nuclear power plant, located about 50 miles from Kalamazoo.
The Palisades plant, owned by the Entergy Corporation, joins two other plants singled out for closer inspections, according to Prema Chandrathil, spokeswoman for the NRC. The other two plants are the Perry Nuclear Power Plant Unit 1 near Cleveland, Ohio, and the Susquehanna Nuclear Power Plant Unit 1 in Pennsylvania about 70 miles northeast of Harrisburg.
Chandrathil said the only plant that ranks lower in the NRC's categories is the Browns Ferry Nuclear Plant in Athens, Alabama, 32 miles west of Huntsville.
As a result of the latest incidents at the Palisades, Chandrathil said, "An additional team of inspectors will be used to conduct 200 hours of additional inspections."
Mark Savage, spokesman for the Palisades plant, acknowledged the findings by the NRC and said, "We've cooperated fully with the agency, and we've shared information with them." Savage said the company will work with the NRC to plan future inspections.

Physician: “When it comes to Fukushima, we are all downwinders”
Nuclear waste stockpile – Ottawa Citizen
.
Dale Dewar, Ottawa Executive Director, Physicians for Global Survival (Canada)
[...] My physics professor in 1962 was skeptical about the environmental cost of nuclear power. He could not have been the only person to raise a voice of caution so I’m sure that, beneath the superficial history of nuclear power, there is a story of deals, deception, and press releases.
While we students thought that the professor was a bit of a fuddyduddy, time has proven him correct. The actual cost of nuclear power is beyond our wildest dreams. [...]
Given that birds and insects affected by Chernobyl are showing chromosomal abnormalities, there is no reason to suspect that humans cannot expect the same over generations.
When it comes to Fukushima, we are all downwinders.

NRC approves new nuclear reactor design
Associated Press
December 22, 2011, 10:11 a.m.
.
WASHINGTON — Federal regulators have approved a nuclear reactor designed by Westinghouse Electric Co. that could power the first nuclear plants built from scratch in this country in more than three decades.
The Nuclear Regulatory Commission unanimously approved the AP1000 reactor on Thursday. The certification, effective immediately, will be valid for 15 years.
NRC Chairman Gregory Jaczko said the newly approved design would ensure safety through simplified, passive security functions and other features. He said plants using the design could withstand damage from an airplane crash without significant release of radioactive materials — an issue that gained attention after the 2001 terrorist attacks.
Approval of the design is a major step forward for utility companies in Georgia, Florida and the Carolinas that have billions of dollars riding on plans to build AP1000 reactors in the Southeast. Without NRC approval, the utilities could not have gotten a license to build their plants.
Federal officials approved an earlier version of the AP1000 reactor in 2006, but it was never built in the United States. Four AP1000 reactors are now under construction in China.
Aris Candris, Westinghouse president and CEO, said the road to receiving design certification of the AP1000 "has been long and sometimes arduous."
The NRC vote brings the U.S "one step closer to constructing AP1000 units and putting thousands to work to ultimately provide future generations with safe, clean and reliable electricity," he said.
Utilities in Georgia and South Carolina have been waiting for the design certification so they can move ahead with applications to build two reactors in each state.
Atlanta-based Southern Co. applied to build the first two AP1000 reactors at Plant Vogtle near Augusta, Ga. The $14 billion effort is the pilot project for the new reactor and a major test of whether the industry can build nuclear plants without the endemic delays and cost overruns that plagued earlier rounds of building years ago. President Barack Obama's administration has offered the project $8 billion in federal loan guarantees as part of its pledge to expand nuclear power.
Close on its heels is SCANA Corp., which is also seeking permission to build two reactors at an existing plant in Jenkinsville, S.C.
Other applications that use the AP1000 design include two plants in Florida, one and South Carolina and another in North Carolina. Each application is for two reactors.
Even with the design certification, it remains unclear when the Vogtle reactors will receive final approval — a major concern for Southern Co. since any delays could increase the cost of the project.
The biggest difference between the AP1000 and existing reactors is its safety systems, including a massive water tank on top of its cylindrical concrete-and-steel shielding building. In case of an accident, water would flow down and cool the steel container that holds critical parts of the reactor — including its hot, radioactive nuclear fuel.
An NRC taskforce examining the nuclear crisis in Japan said licensing for the AP1000 should go forward because it would be better equipped to deal with a prolonged loss of power — the problem that doomed the Fukushima Dai-ichi plant.
Marilyn Kray, president of NuStart Energy Development, a nuclear industry consortium that has worked to demonstrate the design's effectiveness, said she was pleased to see the design move forward.
"The AP1000 is the reactor design that will set the foundation for the next generation of nuclear plants in the U.S.," Kray said.
A nuclear watchdog group called the vote disappointing, saying the NRC should have done a new analysis in the wake of the Japan crisis, which occurred after a March 11 tsunami sent three reactors at the Fukushima Dai-ichi plant into meltdowns in the worst nuclear crisis since Chernobyl in 1986.
A new study could have helped identify and correct any vulnerabilities based on lessons learned from Fukushima, said Edwin Lyman, a senior scientist at the Union of Concerned Scientists.
"It would be more efficient and cost-effective to address problems that could be corrected at the design stage now, before any new plants are constructed," Lyman said.
After plants are built, any new safety requirements would have to be addressed through costly retrofits and other actions, Lyman said, adding that he was "far from convinced" that the AP1000's passive safety features would be effective in coping with severe accidents.
Under existing rules, a reactor design that commissioners have voted to approve must be published in the Federal Register for 30 days before it is legally effective. Southern Co. officials asked the NRC to make the design effective immediately after the vote, a request that was granted. Publication in the Federal Register is expected by Jan. 5.

Asahi poll: 57% of Japanese say no to nuclear power
.
December 13, 2011
.
Fifty-seven percent of voters are opposed to nuclear power generation, while 30 percent are in favor, according to an Asahi Shimbun survey.
The 57-percent figure compares with 48 percent recorded in a survey in October. The latest nationwide poll was conducted Dec. 10-11.
Since April, one month after the crisis at the Fukushima No. 1 nuclear power plant, The Asahi Shimbun has incorporated questions on the use of nuclear power in its monthly poll.
In the December survey, male respondents opposed to nuclear power outnumbered those in favor for the first time.
The non-support rate for nuclear power has continued to exceed the support rate since an Asahi poll covering several countries in late May.
The non-support rate among females, which has consistently been higher than the support rate since mid-May, hit the 60-percent mark for the first time in the latest poll at 65 percent.
For males, the support rate came to 47 percent in the October survey, and the non-support rate was 38 percent.
The figures, however, came out in reverse in the latest poll, with the non-support rate at 49 percent and the support rate at 43 percent.
Concern about radioactive substances remains strong.
When asked to rate their concern, in terms of the effects on their own health and that of family members, four choices were offered. The answers "Greatly" and "fairly" accounted for a combined 67 percent.
A majority of those who answered "Not very concerned" supported nuclear energy in the September survey. However, the majority of those who chose that answer in the December poll was opposed to its use as a source of power generation.
Seventy-seven percent of the respondents favor the phasing-out of nuclear power in the future.
But when asked about the Noda administration's policy on natural energy promotion, 70 percent responded that they either "Cannot expect much" or "Cannot expect (anything) at all," a substantial spike from the 44 percent recorded in September.

Ammonia leak at San Onofre nuclear plant prompts emergency alert
November 1, 2011 | 4:37 pm
San Onofre Nuclear Generating Station
An ammonia leak prompted officials to declare a Level-Two emergency at the San Onofre nuclear power plant and evacuate some workers, officials said.
The leak posed no danger to the public, and no radiation was released during the emergency, said Lauren Bartlett, a spokeswoman for Southern California Edison.
Under federal regulations, there are four emergency levels, depending on the severity of the situation. Level Two involves any "potential substandard degradation in the level of safety of the plant."
The leak was detected about 3 p.m in the No. 3 make-up water treatment system in the non-nuclear section of the plant, Bartlett told The Times. The leak was confined to Unit Three.
Employees in the area of the leak were evacuated. Other plant employees remained at their workstations. Units One and Two were operating normally, Bartlett said.

Radioactive water found beneath Georgia nuclear Plant Hatch
By Associated Press
For the AJC...
8:03 p.m. Friday, September 30, 2011
.
Radioactive water has been found underneath a nuclear power plant in southeast Georgia, but officials said Friday that the leak does not pose an immediate threat to public health and is unlikely to contaminate any drinking water.
The Atlanta-based Southern Co. learned of the leak beneath Plant Hatch in Baxley on Wednesday when it identified radioactive tritium in two test wells about 25 feet below the ground, said Dennis Madison, a utility vice president who oversees the plant.
Workers guided by ground-penetrating radar were planning to dig Friday to identify the source of the leak.
Exposure to tritium increases the risk of developing cancer. But it emits low-level radiation and leaves the body fast, making it one of the least-dangerous radioactive elements.
Madison and state environmental officials say it is unlikely plant workers or residents will be exposed to the radiation because it is confined to an area within the facility and was not headed toward any drinking water supplies.
"This water is totally contained right under the industrial footprint of our plant," Madison said.
He said the utility hoped to identify the source of the leak no later than Sunday afternoon and intended to have it repaired early next week. While the size of the leak was unknown, it was enough to raise the water table in the wells about five feet. Both reactors at the site were functioning normally and showed no other signs of water loss.
"We really don't know what the rate is," Madison said. "We know it's more than a drip."
Tritium is a radioactive form of hydrogen that gets created as a byproduct inside nuclear reactors. It is commonly found in water.
The maximum concentrations of tritium reported inside the wells was more than 200 times the limit set by the U.S. Environmental Protection Agency for drinking water, according to a report that Southern Co. officials filed with the U.S. Nuclear Regulatory Commission.
So far, testing by the utility shows no signs that tritium from this leak has gotten into aquifers that supply drinking water or into the nearby Altamaha River, which provides cooling water for the nuclear plant.
The contours of the ground would tend to move the tritium away from the nearest private well, which is roughly a mile from the site, and toward the river, said Jim Hardeman, manager of the state's environmental radiation program.
"At least as of right now, it's not making its way off the site, either to the Altamaha River or toward anyone's drinking water," Hardeman said. "The odds of this getting into anyone's drinking water are minuscule."
The plant, which started producing power more than 30 years ago, has previously suffered from tritium leaks. Southern Co. hired a consultant in the late 1970s and early 1980s to investigate earlier leaks, according to a report from the utility.
In 2006, the company replaced piping and made other repairs to fix or prevent tritium leaks near where the problem was discovered this week.
NRC spokesman Roger Hannah said the agency was notified of the leak and was monitoring it.

Agency approves construction of nuclear plant in Alabama
By Tricia Escobedo, CNN
August 19, 2011 6:07 p.m. EDT
.
(CNN) -- The Tennessee Valley Authority has approved construction on a nuclear plant in northeastern Alabama -- the first U.S. agency to do so since the Japan nuclear disaster this year.
The TVA board of directors -- which approved the $4.9 billion project Thursday night -- said the Bellefonte project could create 2,800 construction jobs in north Alabama as well as 650 permanent jobs once the plant is complete.
It estimates the plant will be online in 2020 and will provide enough megawatts to power about 750,000 homes in the region.
The TVA still needs approval from the Nuclear Regulatory Commission before it can start construction at Bellefonte, a commission spokesman said.
"TVA still has work to prove they're in a position to start construction," commission spokesman Scott Burnell said. "But TVA's decision yesterday marks their formal re-entry into the process of completing the plant and bringing it online."
It could take months before the agency grants a full construction permit to the TVA.
The triple meltdown at Japan's Fukushima Daiichi power plant after the March 11 earthquake and tsunami was the worst nuclear accident in a quarter-century. It displaced more than 100,000 nearby residents, and engineers are still working to restore normal cooling in the three reactors that melted down.
The NRC has made "recommendations" for nuclear plant operators in light of Fukushima, but it has not yet made any "new or enhanced requirements," Burnell said.
Nevertheless, TVA said it is taking into account the "lessons learned" from the Japan nuclear disaster.
"As we build Bellefonte we will integrate safety modifications from the extensive review of the lessons learned from the Fukushima nuclear plants in Japan," Tom Kilgore, TVA president and CEO, said in a statement.
Construction on the Bellefonte nuclear site began more than 37 years ago, and the facility is already 55 percent complete. It's near Scottsboro, Alabama, about 40 miles east of Huntsville.
Construction at Bellefonte was halted in 1988 because, according to the TVA, there wasn't a need for the increase in power at the time.
"Now because demand continues to grow, they (the TVA board members) are looking at other options and Bellefonte is one of them," TVA spokeswoman Barbara Martocci said.
CNN affiliate WAAY-TV in Huntsville reports that local business owners are excited that the new nuclear plant could help boost their sales.
"Well, I hope it will increase it about 25 percent," restaurant owner Miles Smith told WAAY. "That will be a big, big impact; it really will."
The project also has its opponents. The Southern Alliance for Clean Energy warns that not only is there "compromised radiation containment in the unfinished reactor" at Bellefonte, but it would be a "financial gamble" to get any of the Bellefonte reactors back online.
"The Southern Alliance for Clean Energy has serious concerns about TVA's push to complete the mothballed, abandoned Bellefonte reactors," Steven Smith, the group's executive director, said in a statement.
The NRC said the TVA has a lot of work to do before it can start new construction at Bellefonte.
"TVA is still in the information-gathering and information-providing phase prior to the NRC granting full authorization to grant construction," Burnell said.
The TVA board also approved a 2 percent rate increase starting on October 1 to pay for "nuclear safety modifications as a result of Fukushima" as well as cybersecurity measures and clean-air initiatives, it said.
The nearly 9 million customers indirectly serviced by the TVA will pay an average of $1.60 more a month on each 1,000 kilowatt-hour bill, the TVA said.
The price hike will not directly fund the Bellefonte project, according to Martocci.
She said the board is looking at paying for the project through "alternative financing" as well as borrowing through bonds.
"We'll look at that, and certainly anything we do comes from the revenue we get from the sale of electricity. We don't get any money from the federal government," Martocci said. "What we're trying to do is reduce the cost to our consumer as much as possible."

It's now time for a story that restores your faith in mankind, even if it means going all the way to Japan to find it: In the five months since that country's devastating quake and tsunami, almost $78 million in cash has been found amongst the wreckage and turned in.
The money was recovered from countless abandoned wallets and purses, as well as from 5,700 safes that have washed up along the coastline. One safe alone was said to contain $1 million. But what were these coastal villagers doing sitting on so much cash in the first place? From the Daily Mail:
It is not unusual for the Japanese to keep large amounts of money at home and at offices, particularly in the coastal regions where fisheries companies prefer to deal with cash transactions.
Police have hired specialists to cut open the safes, and their rightful owners are being contacted based on the personal information contained inside.
'The fact that these safes were washed away, meant the homes were washed away too,' [said Koetsu Saiki, of the Miyagi Prefectural Police.] 'We had to first determine if the owners were alive, then find where they had evacuated to.' [...]
'[T]he fact that a hefty 2.3 billion yen in cash has been returned to its owners shows the high level of ethical awareness in the Japanese people,' said Ryuji Ito, professor emeritus at Yokohama City University.

Japan To Nationalize Nuke Plants: Report
Japan’s Tokyo Electric Power Co (TEPCO), the operator of the Fukushima nuclear plant devastated by the March 11 earthquake/tsunami, may be broken up, according to a newspaper Sunday. According to the plan, the company would sell its power distribution business under state control and be left generating power using thermal and hydraulic power plants. It was drawn up by Deputy Chief Cabinet Secretary Yoshito Sengoku, who informed TEPCO chairman Tsunehisa Katsumata about the proposal, said the report. Last month, the government helped draft legislation to assist TEPC in compensating those impacted by the nuclear plant.NBC L.A. ...

Judge rules polar bears still 'threatened'
June 30, 2011 | 3:51 pm
Polar A U.S. District Court on Thursday upheld a Bush-era decision that polar bears are a threatened species, despite challenges by the state of Alaska and others seeking to strip the bear of its protection.
Judge Emmet Sullivan ruled that the U.S. Fish and Wildlife Service’s decision to protect the bear because of the melting of the Arctic sea ice was well supported and that opponents failed to demonstrate that the listing was irrational.
“Plaintiffs’ challenges amount to nothing more than competing views about policy and science,” Judge Emmet Sullivan wrote.
The polar bear was the first species added to the Endangered Species List solely because of the threat from global warming.
The status of polar bears became an issue in 2005 after the Center for Biological Diversity, Natural Resources Defense Council and Greenpeace filed a petition arguing that shrinking ice impaired the bears' ability to catch prey and could lead to their extinction. In December 2006, then-Interior Secretary Dirk Kempthorne declared the bears "threatened," rather than endangered and in imminent danger of extinction. Endangered and threatened species receive the same protections, such as protection of critical habitats, population recovery assistance and prohibition of harm to the species or its habitat. For threatened species, however, the government can reduce protections or allow exemptions.
If the bears were listed as endangered, new power plants could be blocked, as well as other sources of carbon dioxide and other gases that contribute to global warming. It also could make petroleum exploration more difficult.
As a result, Kempthorne created a "special rule" stating that the Act would not be used to set climate policy or limit greenhouse gas emissions, pesticides, mercury and other pollutants outside of the Arctic that harm the bear. The Obama administration upheld this policy.
The state of Alaska and hunting groups argued that the listing was unnecessary because the bear is protected by other laws.
“With the population of the species in decline, the needless hunting of them for sport must not be an option,” said Jeffrey Flocken, D.C. Office Director, International Fund for Animal Welfare. “As pro-trophy hunting organizations continue the fight to skirt existing laws and import polar bear trophies, today’s decision serves to reinforce the fact that the species is in jeopardy. The short-term special interests of hunting groups must never take precedence over long-term conservation efforts for the protection of polar bears.”
Currently, conservation groups are challenging Kempthorne's special rule in court.
“This decision is an important affirmation that the science demonstrating that global warming is pushing the polar bear toward extinction simply cannot be denied,” said Kassie Siegel, director of the Center for Biological Diversity’s Climate Law Institute. “While we are disappointed that the polar bear will not receive the more protective endangered status it deserves, maintaining Endangered Species Act listing for the polar bear is a critical part of giving this species back its future.”
Studies show that rising temperatures are quickly melting the Arctic sea ice, forcing polar bears inland. In September 2007, scientists at the U.S. Geological Survey released a comprehensive nine-volume analysis of the science and reached a dire forecast: Two-thirds of the bear's habitat would disappear by 2050.
Polar bears are experts at hunting ringed seals and other prey on sea ice. But they are so unsuccessful on land that they spend their summers fasting, losing more than 2 pounds a day. Overall, scientists believe the global population of 20,000 to 25,000 polar bears remains robust. But virtually all polar bear experts predict rapid population declines in the Arctic, which is warming faster than anyplace else in the world, changing too rapidly for the bears to adapt and find another source of food.
