ENCLOSURE 2 PVNGS Technical Specification Bases Revision 62 Summary of Changes

ENCLOSURE 2 PVNGS Technical Specification Bases Revision 62 Summary of Changes Technical Specification Bases Revision 62 includes the following changes:

• LDCR 13-B002 reflects conforming changes to the Technical Specification (TS) Bases to implement License Amendment 195, dated March 30, 2015.

The changes involve the adoption of TSTF-486, Revise MTC Surveillance for Startup Test Activity Reduction (STAR) Program (WCAP-1 7787). Specifically, Surveillance Requirements 3.1.4.1 and 3.1.4.2 were modified.

• LDCR 14-B008 reflects clarification of the TS Bases description of a dropped 4-fingered Control Element Assemble (CEA), consistent with the CRDR 4584784 Evaluation. Specifically, TS Bases 3.3.1, Reactor Protective System (RPS) Instrumentation- Operating, has been updated to reflect that the protection for the 4-finger CEA event is provided by installed thermal margin and operator actions to reduce power to meet the requirements of the Core Operating Limits Report (COLR).

These LDCRs were implemented in TS Bases Revision 62 which was made effective April 15, 2015.
