As Japan commemorates the anniversary of the Hiroshima atomic bomb attack, Japanese officials are developing new energy policies that will guard the safety and the livelihood of the Japanese public in the wake of the devastating Fukushima nuclear accident.

Sixty seven years ago today, on Aug. 6, 1945, nearly 140,000 people were killed by the first atomic bomb used in warfare. Three days later the United States dropped another bomb in Nagasaki that killed 70,000 more.

In March 2011, Japan was devastated by an earthquake and tsunami which crippled Tokyo Electric Power Co.’s Fukushima nuclear plant and sent it into meltdown.  This caused radiation to spew over large areas from which more than 160,000 people had to flee. Every one of Japan’s nuclear plants were shuttered in the months following the world’s worst nuclear crisis since Chernobyl in 1986.  This is a country that now knows, all too well, the devastation of nuclear power both in war and in peacetime.

Two of the nation’s reactors resumed operations in July, but the Fukushima disaster has turned public sentiment against the country’s dependence on nuclear power.

According to NBC News, a recent parliamentary investigation concluded that past energy policy reliance on opinions of industry experts, bureaucrats and politicians had bred collusion and blindness when it came to ensuring nuclear reactors’ safety.

Now Japan is conducting citizen debates to look at options for the role of nuclear power in their generation mix, and expects to compile a draft of its new energy policy by the end of August.

Thirty-seven clean energy groups submitted a formal petition for rulemaking to the federal Nuclear Regulatory Commission seeking adoption of new regulations to expand emergency evacuation zones and improve emergency response planning around U.S. nuclear reactors.  If you would like to sign on as a co-petitioner, click here.

Calling on the NRC to incorporate the real-world lessons of the Fukushima nuclear disaster, the proposed rules would expand existing emergency evacuation zones from 10 to 25 miles around nuclear reactors and establish a new zone from 25-50 miles around reactors for which utilities would have to identify and publicize potential evacuation routes. Another improvement would require utilities and state and local governments to practice emergency drills that includes a natural disaster that either initiates or occurs concurrently to a nuclear meltdown. Currently, utilities do not have to show the capability to conduct an evacuation during a natural disaster—even though, as seen at Fukushima, natural disasters can cause nuclear meltdowns. The petition would also expand the “ingestion pathway zone,” which monitors food, milk and water, from 50 miles to 100 miles around reactors.

“80% of the airborne radiation released from Fukushima went directly over the Pacific Ocean,” explained Michael Mariotte, executive director of Nuclear Information and Resource Service, which initiated the petition. “Even so, the Fukushima evacuation zone extended more than 25 miles to the northwest of the site, and the NRC and U.S. State Department both recommended that U.S. citizens within 50 miles of Fukushima evacuate. Such evacuations could not be effectively conducted in the U.S. under current emergency planning regulations. We need to be better prepared and we can’t rely on favorable wind patterns to protect the American people.”

The NRC has relied primarily on the 1979 Three Mile Island accident and subsequent computerized accident simulations to support its emergency planning rules. But first at Chernobyl in 1986, and now at Fukushima, the real world has trumped any possible simulation. The fact is that far too many Americans live near nuclear reactors, but outside existing emergency planning zones. Based on real-life experience, these people need better protection.

“There is no invisible lead curtain surrounding nuclear power plants. We need to incorporate lessons learned from previous nuclear disasters. At the very least, we should stop pretending that emergency evacuation zones of 10 miles are adequate, and expand planning to include residents living within 50 miles of a nuclear power plant,” said Eric Epstein of Three Mile Island Alert in Pennsylvania. “On Friday, March 30, 1979–while school was in session–Governor Thornburgh recommended a ‘precautionary evacuation’ for preschool children and pregnant women living within five miles of Three Mile Island. The targeted population was estimated at 5,000, but more than 144,000 central Pennsylvanians from 50 miles away fled the area–further proof that a radiological disaster is not a controlled field trip.”

Indian Point, 24 miles from New York City, sits at the epicenter of the most demographically dense area of any nuclear reactor in the nation.  Even under normal conditions, traffic is congested and regional infrastructure is highly stressed.  During the severe snow, rain and wind storms of the past few years, large swaths of the region have been brought to a near standstill.  And yet the NRC ignores all these realities, preferring to play with its computer models.  This is a dangerous game.

In light of the recent activities around nuclear plants both in the United States and in Japan it had become obvious that new Emergency Planning Zones need to be implemented. Japan is still experiencing unfolding occurrences that are taking place outside of their projected protected zone. The United States must move to protect her citizens who are in these dangerous pathways.

A third of the population in the U.S., or roughly 120 million people, lives within a 50 mile radius of a nuclear reactor. Current emergency planning rules require utilities to develop and exercise emergency evacuation plans within a 10 mile radius around reactors. The “ingestion pathway” currently consists of an area about 50 miles in radius and focuses on actions appropriate to protect the food ingestion pathway.

At Fukushima, and earlier at Chernobyl, interdiction of contaminated food and liquids has occurred further than 100 miles from the accident sites.

Japan is already acting to improve its emergency response capability, in the event nuclear reactors ever are allowed to operate there again. Prior to the disaster at Fukushima, the emergency planning zones for nuclear emergencies in Japan was between 8-10 kilometers (5-6 miles). The zone is now being expanded to 30 kilometers (18 miles). The actual Fukushima evacuation zone was a 20 kilometer (12 mile) radius around the site, although areas to the northwest had the heaviest radiation measurments on land.

Among the recommendations for managing the current stockpile of spent nuclear fuel — approximately 65,000 tons of waste stored at about 75 operating and shut-down reactor sites around the country — is a plan to move the waste to temporary storage sites.

Public Citizen rejects this plan. In the absence of a permanent and viable solution, we and more than 200 other organizations advocate safeguarding the waste where it is generated.

Tell your representative in Congress to reject efforts to move radioactive waste to temporary dump sites.

The temporary dump plan is flawed for several reasons:

  • It would put tons of lethal radioactive waste on our highways, rails and waterways. An accident in transit could put whole communities at risk.
  • It would condemn a few targeted communities to being radioactive waste dumps for the whole country. Past attempts to place temporary dumps targeted Indian reservations and poor communities of color by offering substantial financial incentives.
  • The temporary dumps could become permanent if no suitable geological repository site is found.
  • It does not address an existing critical vulnerability of nuclear waste storage: almost all reactor fuel pools are filled to capacity. Fuel that is cool enough to move is stored in outdoor casks. Both types of storage are vulnerable to accidents, attack and natural disasters, as shown so clearly by the Fukushima nuclear disaster.

To better safeguard this waste, we advocate hardened on-site storage — a plan that calls for emptying the waste storage pools and placing the irradiated rods in high-quality outdoor casks fortified by thick bunkers and berms.

Ideally, we should stop generating nuclear waste, but while it continues to accumulate, we must implement smart safeguards to protect people and the environment from the immediate risks associated with high-level radioactive waste.

Tell your representative to increase nuclear waste safety at reactor sites.

The Shroud of Fukushima

Artist rendering of the Shroud of Fukushima

According to the London Telegraph, Tokyo Electric Power Co (Tepco) has announced that they will start construction of a shroud over the No. 1 reactor at the ill-fated Fukushima Dai-ichi power plant where a hydrogen explosion destroyed the walls and roof of the reactor building on March 12, the day after the cooling system was knocked out by the Japanese earthquake and the tsunami that it triggered.

The shroud will stand 177 feet high and be 154 long with a roof that can be opened to give cranes access to the interior. It will also be fitted with filters that, over time, will scrub the air inside the building of radioactivity, enabling workers to enter the plant.  The frame of the shroud will be put together off-site and once in place, it will be covered with polyester fiber panels coated with a resin designed to prevent further radiation leaking into the atmosphere – at least that’s the plan.

Tepco is using the operation at the No. 1 reactor to test the construction methods and effectiveness of the shroud.  In truth, they are not sure how effective the temporary cover may be in limiting emissions of radiation from the reactors and spent fuel pools, but it will at least prevent more rainwater entering the buildings and becoming contaminated with radiation.  If it proves effective they have plans to build similar covers over the No. 3 and No. 4 reactor buildings, which were also damaged by explosions after the tsunami.

Eventually, Tepco plans to erect a concrete structure around the reactors, but that will take several years to achieve.  A similar concrete sarcophagus was built over the remains of the reactors at the Chernobyl power plant after that facility was destroyed in an accident in April 1986.

In hearings on Capitol Hill, the Senate Committee on Environment and Public Works was questioning the NRC’s chairman, Gregory B. Jaczko about the implications of Japan’s nuclear accident for the United States.  A statement by a commission official on Wednesday indicated that the nation’s nuclear safety rules had failed to consider the possibility of losing both off-site power from the electric grid and on-site emergency diesel generators.

NRC Commissioner George Apostolakis said that this condition produces a station blackout, and the commission has a rule covering such blackouts, but Mr. Jaczko said that the thrust of the statement was that the agency had not thought enough about a single event that would damage both the grid and the diesel backup generators, causing a plant to take longer to recover.

Let’s hope the US is not the next country designing a sarcophagus for a nuclear facility.

Wanted: Short term, possibly long term position that pays thousands of dollars for up to an hour of work requiring little training working in perilously radioactive environments.

A Tokyo Electric Power Co. (TEPCO) official said this week that the company has tasks fit for “jumpers” (ジャンパー) — workers so called because they “jump” into highly radioactive areas to accomplish a job in a minimum of time and race out as quickly as possible.  Sometimes jumpers can make multiple runs if the cumulative dosage is within acceptable limits — although “acceptable” can be open to interpretation.  In cases of extreme leaks however the radiation might be so intense that jumpers can only make one such foray in their entire lives, or risk serious radiation poisoning.

Asked how the contaminated water could be pumped out and how long it would take, a TEPCO official replied: “The pump could be powered from an independent generator, and all that someone would have to do is bring one end of the pump to the water and dump it in, and then run out.”

Translation: Jumpers wanted.

In its attempts to bring under control its radiation leaky nuclear power plant that was severely damaged by last month’s massive earthquake and tsunami,  TEPCO is trying to get workers ever closer to the sources of radiation at the plant.

Workers are reportedly being offered hazard pay to work in the damaged reactors of up to $5,000 per day.

So if you aren’t concerned about the quality of your life 10 to 15 years down the line and are not planning on having children, this may be the job for you.

The tragic events unfolding in Japan demand a re-examination of U.S. nuclear policy.  While stocks in nuclear plummet and nuclear industry lobbyists scramble on Capitol Hill to shore up support for massive federal subsidies to kick-start the stagnate industry, concerns regarding the existing aging fleet are surfacing and should be heeded.  Click here to read more about specific concerns about some of the aging US nuclear fleet.

Amazingly, despite emerging concerns about existing and proposed reactors, the Obama administration has said it will not back off its plans to further prop up the nuclear industry through increased taxpayer-backed loan guarantees and the inclusion of nuclear power technology in the administration’s clean energy standard. The administration has included $36 billion in loan guarantees in its budget proposal for fiscal year 2012. Instead, it should immediately halt subsidies and instead focus on developing solar and wind power.  Take Action on Nuclear Subsidies

The administration  must take off the blinders, look hard at what is going on in Japan and realize that yes, a catastrophe can happen here.

San Antonio’s electric utility, CPS, has halted their negotiations on a power purchase agreement between CPS and STP’s expansion units 3 and 4.  CPS’s CEO, Doyle Beneby, announced that CPS and NRG have mutually agreed to terminate their PPA negotiations at this point. 

It would appear that the issues facing NRG’s Japanese partners (including Tepco, the beleaguered owners of the doomed Fukushima nuclear plant) are giving everyone pause in their relentless pursuit of the STP expansion.
