GNS launches CASTOR® cask for Japan


Type certificate applied for – Subsidiary founded in Tokyo

GNS has developed the CASTOR® geo26JP cask especially for up to 26 PWR fuel assemblies – the largest available capacity for fuel assemblies from the PWR nuclear power plants most widely used in Japan.
Following the application for a type certificate submitted to the Japanese Nuclear Regulation Authority (NRA) in March, GNS will now closely accompany the licensing procedure locally. To this end, it founded the subsidiary GNS Japan K.K. at the beginning of the year as a corporation under Japanese law with headquarters in Tokyo.
