[에너지신문] 16 February 2016 - Japanese power utility Kansai Electric and Japan Atomic Power Company (JAPC) have submitted their decommissioning plans for the three nuclear units to the Nuclear Regulation Authority (NRA) for approval.
The units 1 and 2 of the Kansai Electric-operated Mihama nuclear power plant and the unit 1 of JAPC's Tsuruga nuclear plant were all officially shut down on 27 April 2015. JAPC estimates that it will take 24 years to decommission the 341 MW Tsuruga-1 boiling water reactor that started up in 1970. In a first stage (around nine years), JAPC will prepare the reactor for dismantling (including the removal of all fuel); the second phase, also lasting 9 years will be to actually dismantle the reactor and other major equipments. The third stage, taking about 6 years, will involve the demolition of the reactor building.
Kansai Electric expects the decommissioning of 340 MW Mihama-1 and 500 MW Mihama-2 to take around 30 years. Both were commissioned in the early 1970s. The decommissioning of these three units was announced in March 2015, after an assessment of the work needed to meet new post-Fukushima requirements by the NRA.
Kyushu Electric submitted a decommissioning plan for the Genkai-1 nuclear reactor to the NRA in December 2015, while Chugoku Electric has yet to submit a decommissioning plan for the Shimane-1 reactor that it plans to decommission.
