Friday Update

From NEI’s Japan Earthquake launch page:
Updated as of noon EDT, Friday, June 17
Plant Status
  • The Nuclear Regulatory Commission staff said it now appears the agency was mistaken in its early conclusion that the used fuel pool at the Fukushima Daiichi reactor 4 may have lost all cooling water. "According to the latest information, it is unlikely it ever went completely dry," said William Borchardt, NRC executive director for operations, in a progress briefing Wednesday for the NRC commissioners. Concern about the potential for overheating in the pool was a factor in the NRC's conservative call for U.S. citizens to evacuate as far as 50 miles from the plant, NRC Chairman Gregory Jaczko told a congressional committee yesterday. "We are continuing to review and re-evaluate the 50-mile recommendation," he said.
  • Tokyo Electric Power Co. (TEPCO) is preparing to release a revised "road map" today for stabilizing the Fukushima Daiichi site, with an increased emphasis on measures to protect the health of workers in light of new information that some received radiation doses above emergency limits set by the government. The revised plan restricts work hours, creates a system for recording automatically workers' exposure to radioactivity, increases the number of devices available to check for internal exposures, places more doctors at the site round the clock and creates new rest facilities for workers.
  • Testing was suspended yesterday on a system to remove radioactive cesium from waste water because of a leaking valve. Once the valve is replaced and tests are completed, TEPCO plans to put the system in service today. Full operation of the water treatment system is essential to TEPCO's plan to cool the reactors continuously. More than 110,000 tons of contaminated water has accumulated in the complex, and it is increasing at a rate of 500 tons a day as fresh water is poured onto the reactors. The main facility to store contaminated water reached capacity yesterday. Preparations are under way to build more storage tanks, next month at the earliest, and install a backup filtering device by August.
Industry/Regulatory/Political Issues

  • The Senate Environment and Public Works Committee held an oversight hearing June 16 on preliminary results of the NRC's safety review at America's nuclear energy facilities. Witnesses included all five NRC commissioners.
  • China has completed post-Fukushima safety inspections at its 13 operating nuclear energy facilities and is moving ahead with inspections at the 28 facilities under construction, with the goal of completing that work by October. While no new plants will be authorized to start up before the inspections are completed, China has announced plans to move ahead with development of additional nuclear energy facilities, Li Ganjie of the Ministry of Environmental Protection told a visiting U.S. delegation on June 10. The nation hopes to have as many as 100 nuclear energy facilities operational by 2020 to help meet energy demand that is rising at an estimated 10 percent to 12 percent annually.
Upcoming Events
  • International Atomic Energy Agency ministerial conference on nuclear safety, June 20-24, Vienna, Austria.
  • Japan-America Society, "The Future of Nuclear Energy Around the World," June 23, Washington, D.C.
  • Recommendations from the NRC's post-Fukushima task force will be provided to the commission in a report in July. The staff is scheduled to discuss these recommendations with the commission at a public meeting on July 19. Next steps include forming a longer-term task force to address areas identified by the near-term task force. The longer-term review is expected to take approximately six months.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why Nuclear Plant Closures Are a Crisis for Small Town USA

Nuclear plants occupy an unusual spot in the towns where they operate: integral but so much in the background that they may seem almost invisible. But when they close, it can be like the earth shifting underfoot.

Lohud.com, the Gannett newspaper that covers the Lower Hudson Valley in New York, took a look around at the experience of towns where reactors have closed, because the Indian Point reactors in Buchanan are scheduled to be shut down under an agreement with Gov. Mario Cuomo.


From sea to shining sea, it was dismal. It wasn’t just the plant employees who were hurt. The losses of hundreds of jobs, tens of millions of dollars in payrolls and millions in property taxes depressed whole towns and surrounding areas. For example:

Vernon, Vermont, home to Vermont Yankee for more than 40 years, had to cut its municipal budget in half. The town closed its police department and let the county take over; the youth sports teams lost their volunteer coaches, and Vernon Elementary School lost th…
