NRC Staff Proposes Priorities for Post-Fukushima Actions

October 5, 2011

Industry/Regulatory/Political Issues

  • A U.S. Nuclear Regulatory Commission staff paper that prioritizes recommendations from the near-term post-Fukushima task force was released today. The document, which will be the basis for an Oct. 11 commission briefing, divides the recommendations into three “tiers.” The briefing will be webcast
  • Japan’s Nuclear and Industrial Safety Agency has ordered Tokyo Electric Power Co. to provide safety guidelines for its work to stabilize the Fukushima Daiichi nuclear energy facility. The agency said the main objective should be to prevent additional discharges of radioactive material and to reduce radiation levels at the plant over the next three years.
  • A reactor at the Genkai nuclear energy facility in western Japan shut down safely Tuesday because of abnormalities in the turbine generator steam condenser, a non-safety-related component. The operator of the plant, Kyushu Electric Power Co., reported no injuries and no change in radiation levels near the facility.
  • The government of Fukushima Prefecture has begun to train workers who will clean areas contaminated with radioactive material from the Fukushima Daiichi nuclear energy facility. The two-day technical seminars are scheduled in various locations around the prefecture. Ten seminars are scheduled through the end of the year.
  • The Japanese government will check radiation levels in five municipalities outside the 12-mile no-entry zone around Fukushima Daiichi. On Friday, the government lifted its evacuation advisory for the municipalities, which are located between 12 and 18 miles from the nuclear energy facility. Decontamination continues in the areas and residents have not returned to their homes.

Media Highlights

  • U.S. nuclear energy facilities are built to withstand earthquakes, floods, hurricanes, tornadoes and other extreme natural events, Tony Pietrangelo, NEI’s senior vice president and chief nuclear officer, writes in a Real Clear Energy column. The comments also are posted on NEI’s Safety First website.

Upcoming Events

  • NRC Chairman Gregory Jaczko will speak on lessons learned from Fukushima Oct. 24 at the American Association for the Advancement of Science in Washington, D.C. Details are on the AAAS website.

This post is absolutely correct. The fuel in the reactor spent fuel pools at Fukushima was never at any risk. Even with the massive hydrogen explosions in Units 1, 3, and 4, the spent fuel pool walls were sufficiently thick that the pools remained leak tight, with plenty of water inventory.

But the lack of instrumentation to measure and monitor the water level created unnecessary uncertainty about the status of the pools, and the concern about the potential for damage to the spent fuel led to resources being diverted to spray water into the pools, and to the unnecessary NRC recommendation for a 50-mile evacuation distance for U.S. citizens.

There were a number of "technical experts" with anti-nuclear positions who were interviewed by the media during the early phases of the accident who made a lot of incorrect claims about what was happening during the accident. This type of disinformation is very damaging, and that's why the NRC's decision to put improved spent fuel pool instrumentation at the top of the list is exactly the right thing to do.

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...

From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...
