Revising TSR Definitions to Reflect SACs

The treatment of SACs, which are distinguished from programmatic ACs, requires the addition

of related terms to Section 1 of TSRs. Specifically, the following definitions would be needed.

Specific AC An AC that provides a specific preventive or mitigative function for accident

scenarios identified in the DSA where the safety function has importance similar to, or the

same as, the safety function of a safety SSC. (e.g., discrete operator actions, combustible

loading program limits, hazardous material limits protecting hazard analyses or facility

categorization.)
