  • Tokyo Electric Power Co.’s new two-year business plan, released last week, projects that costs for decontaminating the area around Fukushima Daiichi and paying damages to evacuated residents will double from the $62.5 billion estimate from April. The company also expects the $12.5 billion estimated cost for decommissioning the facility to increase significantly. TEPCO is asking the government to review the revised business plan and for continued financial support to meet its obligations. In May, the government assumed 51 percent control of the utility’s shares, in return for allocating funds and assistance for compensation and decontamination.

NRC staff told the agency’s Advisory Committee on Reactor Safeguards last week it believes that installing external containment vent filters on some reactors could be beneficial. The industry, however, said that filtering strategies inside containment that take advantage of the FLEX strategy are the key to mitigating radioactive releases during an accident.

  • Japan’s Nuclear Regulation Authority is investigating whether Kansai Electric Power’s Ohi nuclear plant—the only operating facility in the country—is on an active fault line. The NRA heard last week from a group of experts who have surveyed the fissure. The agency has yet to decide whether the fissure in a 125,000-year-old rock stratum came from seismic activity or if it was caused by a landslide. The Japanese government bans nuclear plant operators from building facilities directly above active fault lines. The NRA said if the Ohi fissure is confirmed to be an active fault, it will halt the plant’s operations.

The NRC has issued for public comment draft interim staff guidance for U.S. nuclear energy facility operators to perform certain flooding hazard assessments in response to a request for information the agency issued in March as part of its response to the Fukushima accident.

The March request calls for licensees to use the latest available information and analysis methods to analyze site-specific hazards, including stream and river flooding, hurricane storm surges, tsunamis, and dam failures.

The following news article originally appeared in NEI’s Nuclear Energy Overview.

Of the 34 nuclear energy facilities in the path of Hurricane Sandy, all responded well and safely to the powerful storm, demonstrating their resilience against severe natural forces.

Careful planning and comprehensive preparations days in advance of the storm paid off at all the facilities, ensuring they were prepared to take the steps necessary to maintain safety against Sandy’s high winds, record flooding and disturbances on the regional electric grid. Highly trained reactor operators and emergency response personnel stationed at the plants throughout the storm took actions beyond their usual duties to protect the power plants and communities that surround them. Additional inspectors from the U.S. Nuclear Regulatory Commission were stationed at each nuclear energy facility to oversee preparation for and recovery from the storm.
