(Information)Application for approval of construction planning regrading "facilities installed in a reactor subsidiary building" of Specific Safety Facilities for Genkai nuclear power station unit No.4

 As for Specific Safety Facilities(SSFs) of Genkai nuclear power station unit No.4, of which we received the permission for a change in reactor installation on April 3, 2019, we divide procedures for applications for approval of construction planning into three: "facilities installed in a reactor subsidiary building", "newly installed buildings", and "newly installed facilities" in the same way as Genkai nuclear power station unit No.3.
 Today, we submitted the application regrading "facilities installed in a reactor subsidiary building" to Nuclear Regulatory Authority(NRA).

 We divide the applications for efficient constructions of SSFs. And we are going to submit the remaining applications of "newly installed buildings" and "newly installed facilities", as soon as we get prepared.

 We will make an effort to deal with the NRA's inspections respectfully and sincerely, as well as to improve safety and reliability of nuclear power stations.

※ SSFs

 They have a function to prevent damages of containment vessel. They are preparation in case cooling functions for nuclear reactor stop and a reactor core gets fatal damages due to terrorism such like an intentional collision of jumbo airplane toward a reactor support building.
