Document history of REGDOC-2.4.3, Nuclear Criticality Safety
REGDOC-2.4.3, Nuclear Criticality Safety, is currently being developed. When published, it will set out requirements for nuclear criticality safety and provide guidance on how those requirements may be met. It will provide information for preventing criticality accidents in the handling, storage, processing and transportation of fissionable materials and the long-term management of nuclear waste.
This document will clarify the minimum physical constraints and limits on fissionable materials to ensure nuclear criticality safety during the construction, operation, decommissioning or abandonment of the licensed facility. It will apply to operations with fissionable materials outside nuclear reactors, except for the assembly of these materials under controlled conditions (such as in critical experiments).
