NRA Issues Draft Review Report: Onagawa-2 Meets New Regulatory Standards
On November 27, the Nuclear Regulation Authority (NRA) of Japan issued a draft review report on its examination of the Onagawa-2 (BWR, 825MW), owned and operated by the Tohoku Electric Power Co., for compatibility with the new regulatory standards.
The report will be officially finalized after being referred to the Japan Atomic Energy Commission (JAEC) and the Ministry of Economy, Trade and Industry (METI), and is opened to the public for comments.
An application to the NRA for a compatibility examination of Onagawa-2 was filed in December 2013. Based on geological characteristics, as well as the fact that the Onagawa-2 unit had experienced a major earthquake, the NRA carried out its examination cautiously, especially vis-à-vis the evaluation of geological features, seismic motion an...more

Kyushu Electric Power Files Decommissioning Plan for Genkai-2 and Seeks Change to Genkai-1 Plan, with Work on Both to Proceed Simultaneously
On September 3, the Kyushu Electric Power Co. filed an application with the Nuclear Regulation Authority (NRA) of Japan for approval of its plan to decommission its Genkai-2 Nuclear Power Plant (PWR, 559MWe). The power company also requested preliminary talks with Saga Prefecture and Genkai Town under nuclear safety agreements with each of them.
While making the application for Genkai-2, Kyushu Electric Power also asked the NRA to approve a change to its decommissioning plan for Genkai-1, the work on which is already underway. It seeks to revise its processes in that way to take advantage of the benefits accrued from carrying out work on the two units at the same time.
However, that move will push back the completion date for Unit 1 eleven years, with the decommissioning work on both units now slated to end in 2054.
The entire decommissioning process for Genkai-2 is divided into four stages, as follows:
Preparing for dismantling.
Dismantling and removing facilities and equipment in the area surrounding the reactor.
Dismantling and removing the reactor itself.
Dismantling and removing the reactor building and ot...more
