The fracture resistance of a cast low carbon manganese ferritic steel intended for containers for spent nuclear fuel has been analysed by combining several approaches.Based on data from three-point bend specimens with shallow and deep cracks the e .ect of crack tip constraint at brittle fracture initiation has been followed.Q -parameter was used for the constraint quanti .cation.The crack length e .ect on the fracture toughness - temperature diagram has been analysed and peculiarities of fracture behaviour in the lower shelf region have been explained.The role of cleavage fracture stress in brittle fracture initiation under the in .uence of crack tip constraint has been analysed.
