SKODA CASK TESTING AND LICENSING REQUIREMENTS

摘要

Last activities in field of licensing cask from cast ferritic steels are summarised with special attention to aspects of material fracture resistance. Main principles of container design are shortly described focusing on the role of thick walled cask made of cast ferritic steel in integrity of whole container. Licensing requirements prescribed by IAEA rules are roughly analysed leading to Certificate of Accreditation from the Czech authority in this field. Testing program including the drop test facility development has been described. As important part of container operational life the monitoring program has been introduced and ways for evaluation of cask material residual lifetime introduced.
