NEI Weekly Update on Fukushima Daiichi

NEI Weekly Update on Fukushima Daiichi – 5/6/11

From NEI's Japan launch page:

Plant Status

Workers entered the Fukushima Daiichi reactor 1 building for the first time since March 11 and installed ventilation equipment that will remove radioactive particles from the air. The plan is to reduce the level of radiation to allow for installation of a permanent reactor cooling system. The planned system, to be integrated with components already in place, includes a heat exchanger to be installed near a reactor building entrance.
Japan is working with both China and South Korea to remove restrictions on Japanese food imports in those countries.
Tokyo Electric Power Co. plans to bring 2,000 more workers to the Daiichi site. The plant work force now numbers 1,000. The new workers would replace those who have been on the job and are reaching their permissible limit of radiation exposure.
Overall, site radiation dose rates continue to stabilize or decrease. The most recent radiation readings reported at the plant site gates ranged from 4.6 millirem per hour to 1.8 millirem per hour.
According to media reports, the Japanese government has asked Chubu Electric Power Co. to shut down reactors at its Hamoka nuclear power plant, about 200 miles southwest of Tokyo. The government asked Chubu to implement safeguards against possible earthquakes and tsunamis.

Regulatory/Political Issues

The U.S. Nuclear Regulatory Commission will continue the licensing process for new nuclear energy plants as it reviews the current fleet of reactors following events at Japan’s Fukushima Daiichi plant, NRC Chairman Gregory Jaczko said May 4 before a joint subcommittee hearing of the U.S. House Energy and Commerce Committee. Much of the hearing focused on the NRC’s cancellation of work on the license application for the Yucca Mountain used fuel repository.
NEI, along with representatives from PPL Corp., FirstEnergy Corp. and Exelon, on May 4 briefed members of the Pennsylvania state legislature in Harrisburg on events in Japan.
NEI representatives on May 6 briefed the Task Force on Energy Supply of the National Conference of State Legislatures on Fukushima issues at the organization’s spring executive meeting in Boston.
The activist group Green Action released an international petition May 2 protesting the Japanese government’s April modifications of the radiation safety standard for schools near Fukushima.

Media Highlights

The New York Times published an article on May 2 in its Science section under the headline “Drumbeat of Nuclear Fallout Fear Doesn’t Resound With Experts.” Various authorities interviewed in the article explained that radiation fears beyond Japan’s borders “are unwarranted” and that “humans are bombarded by so much radiation from so many other sources, including natural ones, that the uptick from Japan disappears as a cause of concern (when) the big picture is considered.”
The Associated Press reported May 3 on a briefing by U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko to the policy group Public Citizen. “I suspect we will look at external flood risk” as part of the agency’s reviews of reactors in the United States in response to flooding issues at the Fukushima Daiichi plant, he said. (See Chairman Jaczko's prepared remarks.)
The Washington Post editorialized on April 30, in a piece headlined “A future for nuclear,” that the United States should keep nuclear energy “on the table” as an important low-carbon energy technology. “The only reason nuclear is attractive, some insist, is concern over global warming. Yet, even if that is the only cause, it is compelling,” The Post opined.
The E&E News publication Greenwire published an article on April 29 examining the U.S. Nuclear Regulatory Commission’s post-Fukushima emergency status, which remains in effect. The article was headlined “NRC chairman’s ‘emergency’ status irks leading Senate Republican.”

The Week Ahead

U.S. Nuclear Regulatory Commission briefing, 9:30 a.m., May 12 on the progress of the task force review of NRC processes and regulations following the events in Japan. The meeting will be webcast.
U.S. House Committee on Science, Space and Technology joint subcommittee hearing on nuclear energy risk management, 10 a.m., May 13, 2318 Rayburn House Office Building, Washington, D.C.

Activists' Claims Distort Facts about Advanced Reactor Design

Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

How many nuclear plants does it take to meet the world's energy needs?

Several weeks ago Joshua Pearce at Clarion University in Pennsylvania released a study titled “ Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology .” In the study he stated... nuclear energy production would have to increase by 10.5% per year from 2010 to 2050 to both replace fossil-fuel-energy use and meet the future energy demands. This line, of course, made the headlines and has been picked up by several outlets and blogs . When looking into his calculations for this statement, he made one assumption error that overstated the above sentence by nearly a factor of three. Page 121, Section 4.1 of the study states: Richard Smalley pointed out that in 2004, the global economy consumed the equivalent of 220 million barrels of oil per day, which converted into electricity terms is the equivalent of 14.5 TeraWatts (TW), or 14,500,000 MegaWatts (MW) (2005). … With a nuclear plant having about 1000 MW (1 GW) of capacity, we would need 14,500...

What Happens During a Refueling Outage?

You may have noticed over the past few weeks that a number of nuclear plants are shut down for refueling outages or are resuming operations after just returning from one. This type of routine outage usually occurs in the spring or fall when electricity demand is low so that nuclear reactors can replace about one-third of the spent fuel rods with new fuel and conduct other routine maintenance and repairs at the plant. To get a better sense of how refueling works at a nuclear energy facility, I spoke with Marcus Nichol, NEI’s senior project manager for used fuel storage and transportation, and asked him to explain the basics. Why does a nuclear plant need to replace one-third of its fuel? Nichol: The main purpose of a refueling outage is to replace older fuel that is depleted—meaning it can no longer efficiently produce energy from nuclear fission reactions—with new fuel. This “used fuel” has typically been used in the reactor for four-and-a-half to six years before it is pe...
