Plant Update

  • Tokyo Electric Power Co. has removed the primary containment vessel dome from Fukushima Daiichi reactor 4. TEPCO published photos and video clips showing the dome being lowered to the ground. The dome will be cut up and stored on site. The company also is preparing to remove the reactor pressure vessel head in October. Steve Kraft, NEI’s senior director for Fukushima response, said these actions are key steps to prepare for the installation of a structure over the building that will allow fuel to be removed from the reactor’s used fuel storage pool. Last week TEPCO also attempted to use a camera-equipped balloon probe to investigate the condition of reactor 1’s refueling floor. The initial attempt was unsuccessful, and the company said it will try again.

  • An independent review of lessons learned from the Fukushima Daiichi and Daini nuclear plants in the aftermath of last year’s earthquake and tsunami, conducted by the Institute of Nuclear Power Operations at the request of Tokyo Electric Power Co., says that reactor operators should allocate resources and training to prepare for unexpected circumstances. Priorities identified include maintaining reactor cooling and multi-unit emergency response capabilities and continually strengthening nuclear safety cultures. Tony Pietrangelo, NEI’s senior vice president and chief nuclear officer, said, “For the U.S. nuclear industry, our first priority is and always will be safety. INPO’s findings are aligned with steps already being taken to enhance safety across our industry.”

IAEA said the mission will include regulators from different countries and other experts. The goal of the trip is to collect information that member nations can use as they develop their own earthquake preparedness and response plans.
