Document description

Draft RD-327 provides requirements for the prevention of criticality accidents in the handling, storage, processing, and transportation of fissionable materials. This regulatory document clarifies the physical constraints and limits on fissionable materials that licensees must implement in order to ensure nuclear criticality safety during the construction, operation, or decommissioning of the licensed facility.

This regulatory document presents CNSC’s requirements regarding nuclear criticality safety. The associated guidance document GD‑327 Guidance for Nuclear Criticality Safety provides information as to how these requirements may be met.
