Virginia Electric and PowerCompany (Dominion) requested an amendment in the form of changes to the Technical Specifications (TS) to Facility Operating Licenses DPR-32 and DPR-37 for Surry PowerStation Units 1 and 2, respectively.
The proposed amendments establish the requirements for the use of a temporary supply line (jumper) to provide service water (SW) to the component cooling heat exchangers (CCHXs). Use of the temporary SW jumper is required to facilitate planned maintenance activities (i.e., cleaning, inspection, repair (as needed), and recoating (as needed)) on the existing, single, concrete-encased SW supply piping to the CCHXs.In support of the proposed license amendment request (LAR), a discussion of the Probabilistic Risk Assessment (PRA) Technical Adequacy was provided in Attachment 4 of the September 26, 2012 letter. On page 2 of 18 of the attachment it states, "The [PRA] model has been updated to address all Category A, B, and D facts and observations (F&Os). There are only 3 Category C F&Os that need to be addressed:..." However, subsequent to the preparation of a PRA technical adequacy review for a separate LAR, it was recognized that a Category B F&O should have also been identified in the September 26, 2012 letter for the temporary SW jumper LAR as follows: F&O Description Significance Importance to Applications IE-5 Determine if an ISLOCA pathway B The increase in CDF and LERF caused by a leak in the RCP associated with this scenario is thermal barrier heat exchanger expected to be negligible based on and a failure to isolate the CCW the low frequency of the initiating lines that provide cooling water event and the redundancy in to the heat exchanger is isolating the leak. Therefore, this applicable to Surry model and gap has no impact on the results address it appropriately, for this application.

Use of the temporary SW jumper is required to facilitate planned maintenance activities (i.e., cleaning, inspection, repair (as needed), and recoating (as needed)) on the existing, single, concrete-encased SW supply piping to the CCHXs.In support of the proposed license amendment request (LAR), a discussion of the Probabilistic Risk Assessment (PRA) Technical Adequacy was provided in Attachment 4 of the September 26, 2012 letter.
