Afternoon Update

From NEI’s Japan Earthquake launch page:

UPDATE AS OF 2:30 PM EDT, MARCH 23:

The U.S. Food and Drug Administration has blocked the import of milk, milk products and fresh vegetables and fruits produced in areas surrounding the Fukushima Daiichi nuclear power plant. FDA is flagging all shipments from Japan to determine whether they originated from the affected area. The agency will test all food and feed shipments from areas near the plant.

Earlier, the Japanese government stopped the sale of raw milk, spinach and kakina (a local vegetable) from areas near the station.

Workers at the Daiichi site continue to inspect equipment to determine whether it can be connected to offsite power sources, which is now available from off-site sources at all six reactors. Off-site power has replaced the use of an emergency diesel generator to provide cooling to reactors 5 and 6, which had been shut down following the earthquake.

Seawater injection continues to cool reactors 1, 2 and 3, and seawater is being sprayed into the reactor 3 spent fuel pool. Water spray continues on the spent fuel pools at reactors 1, 3 and 4.
Radiation dose rates at the Daiichi site boundary continue to range from 1 to 3 millirem per hour.

NEI has also posted a new fact sheet, "Health Impacts of Iodine131."

Wednesday Update

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...

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...

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

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...
