License Amendment Request - Adoption of TSTF-567, Add Containment Sump Technical Specification to Address GSI-191 Issues Pre-submittal Meeting December 9, 2021
2 Agenda Overview of GL 2004-02 and TSTF-567 Adoption of TSTF-567 Schedule for Submittal
3 Overview of GL 2004-02 and TSTF-567 Part of GL 2004-02 Closure Strategy Current closure Option 2a for in-vessel effects pending WCAP-17788 work Analysis result is strainer head loss (hydraulic and structural impact) more limiting than fuel debris (in-vessel) limit for PVNGS (microtherm)
Changing to Deterministic Option 1 (15g/FA acceptance criteria)
PVNGS GL 2004-02 Completion Letter coordinated with LAR submittal Establishes new Licensing Basis for post accident Containment Sump performance
New TS for sump strainer - 90 days for engineering evaluation of new containment debris discoveries UFSAR Update Requires NRC Closure Letter for GL 2004-02 to implement No technical deviations from TSTF-567 Minor editorial variations in the TS and TS Bases (e.g., PVNGS LCO numbers, etc.)
4 Adoption of TSTF-567 Technical Specification/Bases Changes Creates new LCO 3.6.7, Containment Sump
- Condition A - One or more containment sumps inoperable due to containment accident generated and transported debris exceeding the analyzed limits. 90-day Completion time Deletes SR 3.5.3.8 Replaced by new SR 3.6.7.1 for Containment Sump Inspections Modifies SR 3.5.4.1 to remove reference to SR 3.5.3.8 Conforming TS Bases Changes Strainer limits in Study 13-MS-C043 - Rewritten UFSAR Section 6.2.2.2.1 will replace existing Sections 6.2.2.2.1 and 6.2.2.2.2
