IntroductionTokai-1 (GCR, Gas Cooled Reactor) nuclear power plant of the Japan Atomic Power Company started commercial operation in 1966 as the first commercial nuclear power plant in Japan and ceased its operation in 1998. Spent fuel elements were removed out of the reactor core and shipped to the reprocessing plant by June 2001. JAPC (The Japan Atomic Power Company) launched Tokai-1 decommissioning in December 2001 after the submission of the notification of decommissioning plan to the competent authority. This is the first instance of the decommissioning for a commercial nuclear power plant in Japan. The whole project is planned to take 17years in all, reactor area is safe-stored while first 10 years, as shown in Table 1.Tokai-1 decommissioning project has an important role for demonstrating that the decommissioning of commercial nuclear power plant can be executed safely and economically, and for establishing the key technologies for future LWR decommissioning in Japan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
