Japan Cabinet Approves Decontamination Protocols

Nov. 21, 2011

Industry/Regulatory/Political

  • The Japanese cabinet has approved “basic policies” to clean up radioactive contamination resulting from the Fukushima Daiichi accident. Based on recommendations made in 2007 by the International Commission on Radiological Protection, areas contaminated to dose levels within two rem per year above background will be cleaned up to reduce adult doses by 50 percent within two years and 60 percent for children, and to a long-term level of 0.1 rem/year above background radiation levels. Two rem is about the same amount of radiation exposure a patient would receive from a full body CT scan. Areas where the annual dose levels are above two rem/year will be given priority in scheduling decontamination activities.
  • The Japan Nuclear Technology Institute has published a report reviewing the Fukushima Daiichi accident. The Japan Atomic Industrial Forum said the analysis of the accident is based on published facts, operational experience and knowledge of the plant design, and includes recommended safety protection measures “to prevent and mitigate severe accidents.”

Media Highlights

  • The Salt Lake Tribune quotes Adrian Heymer, NEI’s executive director of the Fukushima regulatory response, on how some of the safety lessons from the Japan accident already have been incorporated in the features of new nuclear reactor designs.
  • An Associated Press article explains the difficulty of measuring future health effects of the low doses of radiation resulting from the Fukushima Daiichi accident.
  • A Washington Post article describes the areas around the Fukushima Daiichi plant that have remained evacuated since the March accident following the Tohoku earthquake and tsunami.

Fluor Invests in NuScale

By
You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

By
Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...

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...
