Government Recommends New Regulatory Oversight Agency for Japan Reactors

Plant Status

  • TEPCO is scheduled today to install a metal cover over the turbine building of reactor 3 before Typhoon Ma-on moves toward the Japanese coast on Tuesday. The 15-foot-by-50-foot structure is meant to cover a hole in the building.
  • TEPCO reported that the nitrogen injection into reactor 3 is not holding pressure. TEPCO is checking for leaks from the primary containment vessel. TEPCO said that it has injected more than 200 cubic meters of nitrogen into the containment vessel to stabilize the reactor, but there has been little increase in pressure within the secondary containment structure at reactor 3.

Industry/Regulatory/Political Issues

  • Goshi Hosono, Japan’s minister for nuclear crisis management, said he is drawing up plans for a new nuclear regulatory agency that is independent of the Economy and Industry Ministry. The new agency will incorporate some of the monitoring functions now being performed by the Science Ministry’s Nuclear Safety Commission. Hosono said he wants the new entity to be operational by next April.
  • Japanese reactors that are currently shut down should reopen once their safety is assured, Hosono said. The Nuclear and Industrial Safety Agency has developed two-stage computer-based stress tests to assess the resistance of the reactors to earthquakes, tsunamis, and loss of power and cooling capacity. The first-stage tests will apply to reactors that were shut down for regular inspections. The secondary tests are for all reactors and involve simulations for an earthquake accompanied by tsunami.
  • U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko spoke today on near-term lessons learned from Fukushima at the National Press Club in Washington, D.C. NEI transmitted a letter to the commission on the NRC’s 90-day task force report and recommendations.  Jaczko is seeking a 90-day period for consideration of the task force recommendations, but the industry believes that more data is needed from Japan before many of the recommendations can be reviewed by the five NRC commissioners.
  • Reiterating the urgency of restarting shutdown nuclear reactors, the chairman of the Japan Association of Corporate Executives said the shortfall in electricity supply could cause more companies to shift manufacturing abroad and affect the global competitiveness of Japanese industry.

Upcoming Events

  • The NRC’s near-term post-Fukushima task force will brief the commissioners on its report at a public meeting July 19. A public NRC meeting to discuss the report is scheduled for July 28.

Activists' Claims Distort Facts about Advanced Reactor Design

By
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?

By
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?

By
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...
