Qualification test of concrete cask performance in CRIEPI

摘要

CRIEPI successfully terminated four-years study program of demonstrative tests for interim storage of spent fuel, which is mainly related to concrete cask storage technology in 2003, particularly aiming at the realization of dry storage away from reactor in 2010. Concrete cask storage system is considered to essentially have an economical advantage. The acknowledgements obtained in these demonstrative tests were reflected on Japanese safety guideline of concrete cask issued by METI/NISA (Ministry of Economy and Trade Industry/Nuclear and Industrial Safety Agency) in June, 2004. This paper introduces the qualification test of concrete cask performance of spent fuel storage technology executed in CRIEPI.
