Robot Tests Radiation in Fukushima Reactor Building

Plant Status

  • Work is continuing to reduce radiation levels at Fukushima Daiichi’s reactor 3 building. Tokyo Electric Power Co. has used robots to vacuum radioactive debris and place steel sheets on the floor to decrease the potential for radiation exposure. Pending a reduction in radiation levels,  workers are scheduled to enter the building housing the reactor on July 17 to begin installing new piping to inject nitrogen gas into the reactor containment vessel. The inert gas will reduce the possibility of a hydrogen explosion in the containment building. The company already is injecting nitrogen into the containments for reactors 1 and 2.
  • TEPCO said debris may have clogged a hose, temporarily reducing the flow of cooling water into reactor 1 at Fukushima Daiichi by about one-quarter of normal volume. Normally, the cooling system injects 3.7 metric tons of water an hour into the reactors, but the flow was reduced Monday to about 3 metric tons per hour, setting off an alarm. Workers began injecting more water, restoring normal flow in less than an hour.

Industry/Regulatory/Political Issues

  • The Japanese government is taking over the radiation surveys being conducted by local governments and TEPCO in the area around Fukushima Daiichi. Schools and other areas where children gather will have priority.
  • The mayor of a town in the southwestern Japan prefecture of Saga said he agrees with restarting a nuclear energy facility there. Other prefecture officials must also sign off on restarting electricity production at two reactors at Kyushu Electric Power Co.’s Genkai plant. Thirty-five reactors, representing two-thirds of the country’s nuclear energy capacity, remain shut down because of the effects of the March earthquake and tsunami or for regular inspections.
  • A research ship is collecting samples from the ocean floor near Fukushima prefecture to test for radiation. The research is focusing on shellfish and sandworms.

Media Highlights

  • A New York Times writer toured the LaSalle nuclear energy facility in Illinois and reports on how the plant—and the industry—handles used nuclear fuel.

New Products

  • NEI’s new Safety First website provides information about nuclear safety, security and measures to protect public health.

Upcoming Events

  • The task force reviewing NRC processes and regulations in light of the accident at Fukushima Daiichi will brief the commissioners on the report at a public meeting on July 19. The briefing will be webcast.

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...

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...
