REQUESTS FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THEPILGRIM NUCLEAR POWER STATION LICENSE RENEWAL APPLICATION(TAC MC9669)

Dear Mr. Kansler:

By letter dated January 25, 2006, Entergy Nuclear Operations, Inc. submitted an applicationpursuant to 10 CFR Part 54, to renew the operating license for Pilgrim Nuclear Power Stationfor review by the U.S. Nuclear Regulatory Commission (NRC). The NRC staff is reviewing theinformation contained in the license renewal application and has identified, in the enclosure,areas where additional information is needed to complete the review. These requests for additional information address license renewal scoping and screening aspects for reactor coolant system (Section 2.3.1), engineered safety features (Section 2.3.2), and auxiliarysystems (Section 2.3.3).These questions were discussed with a member of your staff, Bryan Ford, and a mutuallyagreeable date for this response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-1478 or e-mail RXS2@nrc.gov

. Sincerely, /RA/Ram Subbaratnam, Project ManagerLicense Renewal Branch A Division of License Renewal Office of Nuclear Reactor RegulationDocket No. 50-293

The staff requests the applicant to identify the subject components within scope, because it is considered as part of the pressure boundary, and accordingly, it should be within the scope of license renewal and subject to AMR. If, however, the applicant believes that the components do not require an AMR, then they should provide plant-specific justification basedon the description of the subject components, or any other relevant information, as to why the components need not be subjected to an AMR.RAI 2.3.1.1-2The staff believes that the scram discharge piping and volume should be in scope requiringaging management. However, it appears that the subject component was not identified in Table 2.3.1-1 of the LRA. Please justify. RAI 2.3.1.1-3The staff understands that the CRD Housing Supports (CRDHS) limit the travel of a control rodin the event that a control rod housing is ruptured. The supports prevent a nuclear excursion asa result of a housing failure, thus protecting the fuel barrier, and limiting radioactive releases. In addition, following a postulated failure of the drive housing at the attachment weld at the sametime the control rod is withdrawn, and if the collet were to stay unlatched, the housing wouldseparate from the vessel, and the drive and housing would be blown downward against the CRDHS. If credit is taken for the CRDHS; and since, the CRDHS are passive and long-lived,the staff believes that the subject components should be within the scope of license renewalrequiring aging management. It appears, however, that the subject components and their intended function of limiting travel of the control rod following control rod housing rupture have not been identified in Table 2.3.1-1 of the LRA. Therefore, the staff requests the applicant toprovide an explanation.2.3.1.2 Reactor Vessel Internals (RVI)RAI 2.3.1.2-1In Section 2.3.1.2, "Reactor Vessel Internals," it was stated that RVI include local power rangemonitors. The staff understands that the neutron monitoring system (NMS) includes additionalneutron monitors, such as, intermediate range monitors, rod block monitors, etc.; and these monitoring circuits, along with their electrical cables should be within scope of license renewal requiring aging management. The staff also noted that in Table 2.2-1b of the LRA, it was indicated that a bounding approach was used for the NMS. The staff requests the applicant toclarify which neutron monitors and the related cables are considered within scope based on the bounding approach. 2.3.2.1 Residual Heat Removal SystemRAI 2.3.2.1-1The low pressure coolant injection coupling was identified in the Boiling Water Reactor Vesseland Internals Project (BWRVIP)-06 report as a safety-related component. It appears, however, that the component was not identified in Table 2.3.2-1 of the LRA requiring an AMR. If thecomponent exists at Pilgrim Nuclear Power Station, then the staff requests the applicant tojustify its exclusion from aging management; otherwise, submit an AMR for the subject component.RAI 2.3.2.1-2Please clarify whether the passive components, namely, vortex breakers used in pump suctionlines, which could be located inside the emergency core cooling system tanks or in the sump,and whose intended functions are to protect the pumps from cavitation, are subject to an AMR.

If so, identify which of these tanks are equipped with such passive components, and where in the LRA are the AMRs for these components, or provide justifications for exclusion of thesecomponents from AMRs.2.3.2.4 & 2.3.2.5 High Pressure Coolant Injection(HPCI) & Reactor Core Isolation Cooling (RCIC) RAI 2.3.2.4-1The steam supply and return lines for HPCI and RCIC perform safety functions, and therefore,should be in scope of license renewal in accordance with 10 CFR 50.4(a)(1). The staff requests the applicant to clarify whether the subject components are in scope requiring an AMR.
