Abstract
According to IAEA regulations, type B packages should be tested for outer pressure equal to 200m depth and simulating an accident condition . Two types of cylinders are used for uranium-hexafluoride transport cylinders in Japan, which are 48Y-cylinder for natural uranium-hexafluoride and SOB-cylinder for enriched uranium-hexafluoride . the present IAEA regulations have required fire resistance for packagings for enriched uranium-hexafluoride but not for natural uranium-hexafluoride . Considering that uranium-hexafluoride is transported from abroad to Japan by vessel, external pressure tests and some analysis were carried out , with a view to ensure the safety margin of uraniumhexafluoride transport packagings.
