DISCUSSION Reason for Issuance This RG provides guidance for licensee compliance with the TS requirements in 10 CFR 50.36, the reporting requirements in 10 CFR 50.72 and 10 CFR 50.73, and the quality assurance requirements in Criterion XVI of 10 CFR Part 50, Appendix B. This RG endorses NEI 15-03, Revision 3. Background • 10 CFR 50.36 specifies, in part, the requirements for power reactor TS. • 10 CFR 50.36(a) requires applicants for utilization facility licenses to include a summary statement of the bases or reasons for proposed TS, other than those covering administrative controls, but the bases shall not become part of the TS. • 10 CFR 50.36(b) requires each license authorizing operation of a utilization facility to include TS, which are to be derived from the analyses and evaluation included in the safety analysis report, and amendments thereto, submitted pursuant to 10 CFR 50.34, “Contents of applications; technical information.” The Commission may include such additional TS as the Commission finds appropriate. • 10 CFR 50.36(c) requires, in part, the items in the following categories to be included in TS. For this RG, the most relevant categories are the following: o Safety limits, limiting safety system settings, and limiting control settings.  Safety limits for nuclear reactors are limits on important process variables that are found to be necessary to reasonably protect the integrity of certain physical barriers that guard against the uncontrolled release of radioactivity. If any safety limit is exceeded, the reactor must be shut down.  Limiting safety system settings for nuclear reactors are settings for automatic protective devices related to those variables that have significant safety functions. When a limiting safety system setting is specified for a variable on which a safety limit has been placed, the setting must
