Fukushima

Industry/Regulatory/Political

  • Japan’s government has approved restarting two reactors at the Ohi nuclear power plant in the Fukui prefecture in central Japan. The government decision came after the governor of Fukui told Japan’s Prime Minister Yoshihiko Noda that he approved the restart. All 50 of Japan’s reactors have been idled for inspections, the last going off line in May, and the central government has warned of power shortages during the summer. Kansai Electric Power Co., Ohi’s operator, has begun work to restart reactor 3, which the company said should be at full power by July 8. Reactor 4 will be in full operation by July 24. The government is urging people and companies to continue conserving power in the Kansai area, especially if the rainy season ends early. Meanwhile, some major steel and paper companies are planning to build their own power generation facilities and to sell the surplus electricity to utility companies.

NEI is urging the NRC to remain focused on the high-priority recommendations from the agency’s Fukushima task force before proceeding with implementation of the lower-priority items.

“Preliminary industry assessments indicate that the Tier 1 items, when completed, will achieve as much as 90 percent of the safety benefit from all recommendations,” NEI said in a comment letter last week. “At this time, the safety benefits derived from proceeding with implementation of the Tier 2 or Tier 3 recommendations are unclear.”

Plant Update

  • Tokyo Electric Power Co. has published measurements showing that the used fuel storage pool at Fukushima Daiichi reactor 4 is level and can withstand a large earthquake. The company last week released details of building tilt and strength measurements and reported that neither the reactor building nor the pool is tilted and that the pool remains safe to store used fuel. Since the March 11, 2011, earthquake and tsunami, TEPCO has reinforced the support structure under reactor 4’s pool, which contains a full load of used fuel from a reactor maintenance outage at the time of the earthquake.
