Abstract

Ductile Cast Iron (DCI) has not been yet employed for Cask Material in Japan. This might be because there are insufficient material data on fracture toughness and because brittle failure acceptance criteria is not yet established for cask applications. This paper describes the results of materials tests using six fullscale DCI cask bodies, a proposal of brittle failure acceptance criteria based on the fracture mechanics, and the results of its verification tests using a full-scale DCI cask.
