Development of Fresh Fuel Packaging for ATR Demonstration Reactor

Japan gives a good deal of encouragement to development of an advanced thermal reactor (ATR) to secure long-term energy source. And, following a prototype advanced thermal reactor \"Fugen\", a demonstration advanced thermal reactor is now planned to be constructed. Related to development of the demonstration advanced thermal reactor, it is necessary and important to develop transport packaging which is used for transporting fresh fuel assemblies. Therefore, the packaging is now being developed in Power Reactor and Nuclear Fuel Development Corporation (PNC). Currently, PNC is fabricating two prototype packagings based on the final design, and land cruising and vibration tests, handling performance tests and prototype packaging tests will be executed with prototype packagings in order to experimentally confirm the soundness of packaging and its contents and the propriety of design technique. This paper describes the summary of general specifications and structures of this packaging and the summary of preliminary safety analysis of package.
