Evening Report

From NEI’s Japan Earthquake launch page:

UPDATE AS OF 7 PM EDT, MARCH 22:

Tokyo Electric Power Co. reported this afternoon (U.S. time) that it has restored electricity to the control room at the Fukushima Daiichi reactor 3. Lights in the control room were switched on for the first time since the earthquake 11 days ago. Electricity to the reactor 4 control room is expected to be restored shortly.

Power restoration to the control rooms will help technicians as they seek to repair the two reactors’ cooling systems. Workers are seeking to reactivate control room monitoring systems for reactor parameters, such as reactor coolant temperatures and water levels. The company also reported that thermometers at reactors 1, 2 and 3 are working again.

TEPCO said it would try to reactivate a cooling pump for reactor 3 later today or Wednesday (U.S. time). The company said that if the pump functions normally, it could begin cooling the reactor and the spent fuel storage pool.

Workers at the Fukushima Daiichi plant also continued to spray water into the used fuel pools of reactors 3 and 4. A 160-foot long extension arm normally used to pour concrete for high-rise buildings was used to more accurately spray water into the used fuel pool area of reactor 4. Workers also pumped 18 tons of seawater into the reactor 2 used fuel pool.

Japan's health ministry says it detected radioactive iodine levels in tap water above the national safety standard for infants at five locations in Fukushima Prefecture. The agency says the water does not pose an immediate risk to infants, but is advising against consumption of the water or adding water to powdered milk for infants.

Elevated levels of radioactive iodine and cesium were detected in soil about 25 miles from Fukushima Daiichi, but the levels do not pose a health risk, according to Japan’s science ministry.

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

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...

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...
