Cooling Restored for the Used Fuel Storage Pools at All Four Damaged Fukushima Reactors

Plant Status
• Workers at the Fukushima Daiichi nuclear energy facility achieved a major milestone this week as recirculating cooling was restored to the used fuel storage pools at the last of the four damaged reactors. Tokyo Electric Power Co. (TEPCO) activated the cooling system at the reactor 1 pool on Wednesday, marking the first time since the March 11 earthquake and tsunami that the pools at all four reactors have used recirculating cooling rather than water injection. Cooling systems for the pools were restored at reactor 2 on May 31; reactor 3, June 30; and reactor 4, July 31. The cooling systems for the pools at reactors 5 and 6 and the common pool were not damaged. TEPCO released an update to its roadmap to restoration of the facility on Aug. 10.

• TEPCO plans to train approximately 4,000 workers in radiation safety by the end of the year. So far, about 1,900 workers have completed the training. These radiation safety specialists will control exposure to workers at the Fukushima Daiichi facility and measure radiation levels in the 20-kilometer no-entry zone to determine whether it is safe for evacuees to return. The Japanese government said it will consider lifting evacuation orders for zones deemed to be safe.

Industry/Regulatory/Political Issues
• Japan and Vietnam have agreed that Japan will continue to support nuclear energy expansion in Vietnam by building two reactors in the country. The two nations agreed last October that Japan would build two reactors by 2021. Vietnam plans to build 14 reactors by 2030 to meet the nation’s growing demand for electricity. Vietnamese Deputy Prime Minister Hoang Trung Hai said he trusts Japan’s technology and wants Japan to keep providing help. Although Japanese Prime Minister Naoto Kan has called for Japan to reduce its dependence on nuclear energy, the government has said it will honor contracts already in place or under negotiation.

Media Highlights
• Japanese National Policy Minister Koichiro Gemba told The Wall Street Journal he believes the nation should consider building small reactors as part of its energy mix. Prior to the accident at Fukushima, the nation’s energy strategy called for nearly doubling generation from nuclear energy to 50 percent by 2030. The government has put those plans aside and is crafting a new energy policy. In his interview with the Journal, Gemba said the future contribution of nuclear energy in Japan is likely to be below the 26 percent level reached in 2007.

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...

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...
