Technical Safety Requirement (TSR) Format and Content (cont.)

6. Appendices

The Bases Appendix shall provide brief summary statements of the

reasons for the SLs, OLs, and associated SRs. The bases shall show

the numeric values, the conditions, the surveillances, and the Action

Statements that fulfill the purpose derived from the safety

documentation. The primary purpose for describing the basis of each

requirement is to ensure that any future changes to the requirement

will not affect its original intent or purpose.

The purpose of the Design Features Appendix is to describe in detail

those features not covered elsewhere in the TSRs which, if altered or

modified, would have a significant effect on safety. Three areas should

be addressed: vital passive components, configuration and physical

arrangement, and materials.

Numbering System within the TSR Document

Safety Limits

SLs should begin with 2.1 and continue with 2.2, 2.3, etc.

Operational Limits

OLs begin with 3.1 and continue with 3.2, 3.3, etc. Any subdivision of

OLs should be numbered with an additional number added to the

number of the LSC, i.e., 3.2.2, 3.2.3, etc. OLs should be grouped by

principal system or function, and each OL within a group should be

numbered sequentially. LCSs are normally the first requirement within

a group.

For NNFs, a standardized grouping of requirements may be difficult

because of the diversity of facility types. However, many will have the

following subdivisions:
