Enclosure REQUEST FOR ADDITIONAL INFORMATION ALTERNATIVES FOR EXAMINATION OF REACTOR PRESSURE VESSEL SHELL WELDS PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293
Reference:
Letter from Entergy Nuclear Operations, Inc. (ENO), to the U.S. Nuclear Regulatory Commission (NRC) Document Control Desk, Pilgrim Relief Request (PRR)-28, Relief from [American Society of Mechanical Engineers Boiler and Pressure Vessel Code] ASME Code,Section XI, Examinations of Reactor Pressure Vessel Circumferential Shell Welds, Pursuant to Generic Letter 98-05, July 1, 2002.
The NRC staff needs the following information to complete its review of the license amendment request.
- 1., Alternative In addressing the Boiling Water Reactor Vessel and Internals Project (BWRVIP)-05 report, Generic Letter 98-05 states "... perform inservice inspections (ISI) on essentially 100 percent of the [reactor pressure vessel] RPV axial shell welds, and essentially zero percent of the circumferential RPV shell welds, except for the intersections of axial and circumferential welds." PRR-28 does not provide information on the percentage of intersecting circumferential welds that will be inspected as a result of axial weld inspections.
Please clarify ENOs commitment to performing inspections on axial shell welds with regards to the intersections of axial and circumferential welds. Additionally, identify the estimated percentage of circumferential welds that will be inspected under PRR-28.
- 2., Section E.2(a)(4), Low-Pressure Coolant Injection (LPCI), Core Spray (CS), and Residual Heat Removal (RHR) Systems ENO indicated that the LPCI, CS, and RHR systems do not operate at pressures above 400 psig. Considering that the Pilgrim Nuclear Power Station pressure-temperature curves limit pressure to 310 psig over the temperature range of 70 F to 100 F, provide additional details on the controls to prevent an over-pressure event by the LPCI, CS, and RHR systems below 100 F?
- 3., Section E.2(a)(2), Feedwater/Condensate Systems Provide additional details on controls to prevent inadvertent injection by the reactor feed pumps or condensate pumps below 450 F. Additionally, what are the discharge pressures of the reactor feed pumps and condensate pumps?
- 4., Section E.2(a)(3), Standby Liquid Control System Are there any automatic starts to the standby liquid control system?
