B-N, B13.40 01-RC-R-1-VESSEL-LINTERNAL During the MRP-227, Reactor Vessel Internals, and 10-year ISi Examinations that occurred in the S1R31 outage. The following was observed with regards to the thermal shield: thermal shield flexure 30 degrees-Crack like indication in the vicinity of the inner flexure weld CR 1212741; thermal shield flexure 210 degrees-Crack-like indication in the vicinity of the outer flexure weld CR 1212744; thermal shield flexure 270 degrees-Crack-like indication in the vicinity of the outer flexure weld CR 1212743; thermal shield support block cap screw lock bar weld 195 degrees-Indication on lock bar weld on Cap Screw 195L -

CR 1212740; and thermal shield support block 75 degrees-Anomaly noted on left side of thermal shield support block-CR 1212700. PWROG-21021-P, Revision 1, Thermal Shield Support Block Cap Screw and Flexure Degradation Safety Assessment, October 2022, contains a qualitative one-cycle safety assessment for the degradation of thermal shield support block cap screws and thermal shield flexures. The report concludes that there is no safety concern with operation for one cycle with any number of degraded TSSB cap screws and flexures. Westinghouse has evaluated the Surry specific findings in Westinghouse Letter VPA-RV010-TM-CA-000001, Surry Unit 1 Fall 2022 Outage - Disposition of As Found Conditions for the Thermal Shield Supports and Justification for Return to Service and concluded that it is acceptable to operate for one cycle. The anomaly discovered on the 75 degrees thermal shield support block is not evaluated in PWROG-21021-P. Westinghouse also evaluated this condition and concluded that the anomaly does not present a safety concern. These conditions are documented in ETE-SU-2022-0049, Surry Unit 1 MRP-227-1-A Reactor Vessel Internals Examinations Engineering Evaluation-Phase II (CR1213488 -

Results of Surry Unit 1 MRP-227 Phase 2 (Fall 2022)).
