Wednesday Update

From NEI’s Japan micro-site:

NRC Votes Are All In on Task Force Report

Plant Status

• Tokyo Electric Power Co. has begun erecting the steel support for an airtight cover for reactor building 1 at the Fukushima Daiichi nuclear energy facility. The 17-story polyester fiber fabric cover is designed to shield the environment from the release of radioactive particles. TEPCO is planning similar covers for reactors 3 and 4.

• TEPCO has established a means of sampling the liquids and gases in the primary containments at Fukushima Daiichi. Samples have been taken from the containments for reactors 1 and 2.

Industry/Regulatory/Political Issues

• NRC Chairman Gregory Jaczko this morning submitted his voting document on the recommendations of the agency’s post-Fukushima task force. All five commissioners have now cast their votes. The voting papers are on the NRC’s website.

• Residents and business owners evacuated from near the Fukushima Daiichi nuclear energy facility may be permitted to check on their homes and businesses during brief visits next month. The Ministry of Economy, Trade and Industry also said some people from evacuated areas soon may be able to return home permanently. Easing the restrictions would not affect the exclusion zone within 12 miles of the plant, where about 80,000 people were evacuated.

• Japan has agreed to share the lessons learned from Fukushima Daiichi in a summit-level United Nations meeting Sept. 22 in New York. U.N. Secretary General Ban Ki-moon visited Japan this week, including a stop in Fukushima Prefecture.

Media Highlights

• In the early days of the Fukushima Daiichi accident, Japanese government officials withheld information about radiation dispersal that could have assisted evacuees, The New York Times reports.

• Britons see a “major role” for nuclear facilities as part of the country’s energy portfolio, a survey by the Nuclear Industry Association has found. World Nuclear News reports that 68 percent of respondents support nuclear energy.

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...
