NRC Commissioners Direct Staff to Act Promptly on Fukushima Task Force Recommendations

Industry/Regulatory/Political Issues

• The five-member U.S. Nuclear Regulatory Commission has issued a memorandum directing the agency staff to engage with staff experts and external stakeholders to provide the commission with options for agency actions based on the NRC’s near-term task force report on insights from the Fukushima Daiichi accident. The commission requested a report in three weeks noting actions from the task force report that industry should take “without unnecessary delay.” Longer-term actions required by industry would be identified in a separate report within 45 days.

• NHK World reports that the Japan Atomic Energy Agency has created a detailed map showing ground radiation levels within 62 miles of the Fukushima Daiichi nuclear energy facility. The map was developed using a detailed survey conducted in June by a JAEA team. The color-coded map uses Google Earth technology to help users pinpoint locations. JAEA says it hopes the map will help evacuees understand whether it is safe to return home and help government officials with decontamination efforts.

Plant Status

• Tokyo Electric Power Co. noted that its new water decontamination facility began operating this week. The Toshiba-built facility has 14 cesium-absorbing zeolite tanks and has been operating in test mode. The facility is meant to augment the French and U.S. system to clean and recycle cooling water. TEPCO’s efforts to control the volume of water used for cooling include gradually reducing the flow rate of water injected into the reactors.

• TEPCO published an Aug. 17 revision of its roadmap toward restoration from the accident at Fukushima Daiichi. New measures in the revision include a plan to hire and train more staff to conduct radiation protection and survey work.

Media Highlights

• Low levels of radioactive contamination have been detected in rice in Japan, although levels are not hazardous.

Upcoming Events

• The NRC’s full Advisory Committee on Reactor Safeguards will hold a public meeting Sept. 8 to review the agency’s near-term task force report on the events at Fukushima.

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...

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...

How Much Land Does Nuclear, Wind and Solar Really Need?

Not too long ago, we reviewed a report that looked at nuclear energy (and other energy sources) as biodiversity agents. This had to do, in part, with the amount of land a facility needs to function. Nuclear energy and fossil fuel plants use relatively little, wind farms and solar arrays quite a lot of land . Based on an objective and transparent analysis of our sustainable energy choices, we have come to the evidence-based conclusion that nuclear energy is a good option for biodiversity conservation (and society in general) and that other alternatives to fossil fuels should be subjected to the same cost–benefit analyses (in terms of biodiversity and climate outcomes, as well as sociopolitical imperatives) before accepting or dismissing them. Writer Barry Brook, who collected 75 scientists to endorse his paper, is interested in land use as it impacts flora and fauna. Biodiversity concerns do not get as much play as they might – and, when they do, it annoys many when land is withdraw...
