The original IAEA TECDOC 717 prepared at the consensus Consultants Service Meetings contained specific guidance with respect to the application of linear-elastic fracture mechanics principles to the evaluation of potential non-ductile failure for radioactive material shipping package containment boundaries. No specific guidance was provided with respect to elastic-plastic fracture mechanics procedures, due to a lack of consensus. This paper proposes that the inclusion of three alternative elastic-plastic evaluation approaches may provide the basis for consensus guidance to be added to a revised TECDOC. These three alternatives have been incorporated into consensus ASME Code non-mandatory appendices, and are widely accepted in combination. One of the three alternatives, an applied J-integral/crack resistance curve approach, is examined in some detail. (author).
