Contribution to the decommissioning of the Fukushima nuclear power plant.

Since the Great East Japan Earthquake that occurred on March 11, 2011, Rokubishi Rubber has been cooperating with the national project aimed at decommissioning the Fukushima Daiichi Nuclear Power Plant. So far, we have been involved in the development of important airtight mechanisms, including the closure plug for the X-53 penetration, the gripping mechanism and airtight seal for the X-6 penetration connection, and the sealing mechanism for the isolation chamber within the stage, as part of the internal investigation of the reactor containment vessel (PCV). Recently, we delivered a sealed transfer container (double cover port container) to the project, which will be used for the development of retrieval technology aimed at experimentally extracting and analyzing fuel debris. In response to the unprecedented decommissioning work globally, Rokubishi Rubber will continue to take on challenges with our unique sealing technology.
