Schwartz, M W; Boyce, L

Design criteria for preventing ductile and brittle failure are presented for spent-fuel shipping containers fabricated from ferritic nodular cast iron. A data base was assembled to determine the applicability of NRC Regulatory Guide 7.6 to ferritic nodular cast iron. In addition, fracture toughness acceptance criteria for this material were investigated using both fracture arrest and fracture initiation approaches. The study includes a review of the brittle fracture sensitivities of nodular cast iron to various processes involved in its fabrication. 19 figures, 7 tables.
