Request for Additional Information - Entergy Relief Request RR-EN-15 Proposed Alternative to Use ASME Code Case N-789-1 (FLEET SUBMITTAL - MF6341-MF6349)
- Guy, The NRC staff is reviewing the information provided in the subject application dated June 5, 2015 (ADAMS Accession No. ML15159A200) and has determined that additional information is needed to complete its review. Shown below are the NRC staffs request for additional information (RAI). As discussed with you on December 3, 2015, please provide your formal response no later than January 29, 2016. Please treat this email as formal transmittal of the RAI.
REQUEST FOR ADDITIONAL INFORMATION RELIEF REQUEST RR EN-15-1 PROPOSED ALTERNATIVE TO REPAIR DEGRADED CLASS 2 AND 3 MODERATE ENERGY PIPING USING SLEEVES ARKANSAS NUCLEAR ONE, UNITS 1 & 2; GRAND GULF NUCLEAR STATION, Unit 1; JAMES A. FITZPATRICK NUCLEAR POWER PLANT; INDIAN POINT ENERGY CENTER, UNITS 2
& 3; PALISADES NUCLEAR PLANT; PILGRIM NUCLEAR POWER STATION; RIVER BEND STATION, UNIT 1; AND WATERFORD 3 STEADM ELECTRIC STATION ENTERGY DOCKET NOS. 50-313 AND 50-368; 50-416; 50-333; 50-247 AND 50-286; 50-255; 50-293; 50-458; AND 50-382 By letter dated June 5, 2015 (Agencywide Documents Access and Management System Accession No. ML15159A200), Entergy requested the Nuclear Regulatory Commission (NRC) to authorize relief from Section Xl of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) for the specific repair/replacement activity identified in Relief Request RR EN 1. Relief Request RR EN-15-1 provides an alternative repair method for degraded moderate energy Class 2 and 3 piping using ASME Code Case N-789-1 at Arkansas Nuclear One, Units 1 & 2; Grand Gulf Nuclear Station, Unit 1; James A. Fitzpatrick Nuclear Power Plant; Indian Point Energy Center, Units 2 & 3; Palisades Nuclear Plant; Pilgrim Nuclear Power Station; River Bend Station, Unit 1; and Waterford 3 Steam Electric Station.
To complete its review, the NRC staff requests the following additional information.
- 1. Section 5, page 4, of the relief request states Some piping systems are required to be functional and cannot be repaired during refueling outages. The repair of this piping can only be performed when the plant is operating. For this unique case, the reinforcing pad will have to be removed prior to, but no later than, the refueling outage unless specific regulatory relief is obtained. Confirm that the repair will be removed prior to the refueling outage that is scheduled at the end of the fuel cycle during which the repair is performed.

- 2. The licensee includes several restrictions and clarifications in its relief request regarding its use of Code Case N-789-1, such as the case described in question 1 above. However, it is not clear, in all cases, exactly which portions of the Code Case that the licensee will not comply with. (1) Provide a clear description of portions of the code case that will not be followed (2) Provide a clear description of the alternatives to the Code Case (3) Provide the basis for why the alternatives are acceptable.
- 3. Verify that the proposed alternative in Relief Request RR EN-15-1 will only be implemented when the result of complying with IWA-4000 would result in an unscheduled plant shutdown or extended technical specification required actions which could challenge the technical specification completion time requirements.
