ANS 58.16 – Safety Categorization and Design Criteria for Nonreactor Nuclear Facilities

This standard specifies criteria for categorization of SSCs and SACs that have a safety function based on radiological and/or chemical dose and exposure levels for the public and workers. The safety categorization leads to codes and standards that are needed for reliable design, construction, and operations commesurate with the safety categorization.

The purpose of this standard is:

• Specify criteria for categorization of safety SSCs;
• Select industry codes and standards for reliable design, construction, and operations commesurate with the safety organization.

To meet these objectives, the standard specifies the requirements in the following steps:

• identification of hazards;
• evaluation of hazards;
• selection of DBEs;
• unmitigated accident analysis of DBEs;
• identification of safety functions and categorizations;
• selection of safety SSCs to fulfill safety function requirements;
• evaluation, selection, and implmementation of applicable industry codes and standards to ensure safety SSCs are designed, constructed, and maintained to fulfill the intended safety functions.
