Enclosure REQUEST FOR ADDITIONAL INFORMATION NINE MILE POINT NUCLEAR STATION, UNIT NO. 1 (NMP1)
LICENSE AMENDMENT REQUEST (LAR)
REVISION TO TS 4.1.1, CONTROL ROD SYSTEM SURVEILLANCE REQUIREMENTS 1.0 Control Rod System (CRS) performance reliability In order to evaluate the request to scram time test at least 20 control rods every 180 days, past CRS scram function performance should be demonstrated to determine that the scram function reliability has not deteriorated. Therefore, please provide historical scram time data in terms of relevant test results for multiple operating cycles and a description of significant changes in hardware or testing practices that relate to the validity of the data for current plant operation.
2.0 Standard Technical Specification (STS) Surveillance Requirement (SR) 3.1.4.3 In the STSs, SR 3.1.4.3 states: Verify each affected control rod scram time is within the limits of Table 3.1.4-1 with any reactor steam dome pressure prior to declaring control rod operable after work on control rod or CRS that could affect scram time. The licensees October 19, 2006, LAR states that as a precedent, the proposed change to the STT [scram time testing]
SR is consistent with a similar change for Oyster Creek Generating Station (Amendment 249),
however, the Oyster Creek LAR included an SR change similar to STS SR 3.1.4.3. Please provide the basis for not proposing an SR similar to STS SR 3.1.4.3 in the proposed NMP1 LAR.
