OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION RELATED TO LICENSE AMENDMENT REQUEST STP NUCLEAR OPERATING COMPANY SOUTH TEXAS PROJECT, UNITS 1 AND 2 DOCKET NOS. 50-498 AND 499 The Nuclear Regulatory Commission (NRC) staff has reviewed the STP Nuclear Operating Company (STPNOC) request dated June 26, 2007 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML071870252), for approval of an amendment to the South Texas Project, Units 1 and 2, technical specifications (TS) related to control room envelope habitability, in accordance with TS Task Force (TSTF) Traveler TSTF-448, Revision 3.
The staff has determined that additional information is necessary to complete its review of the request. Please provide a response which addresses the following request for additional information questions from the Containment and Ventilation Branch.
- 1.
In Section 2.2, page 1 of 5 of Attachment 1 to your letter dated June 26, 2007 (NOC-AE-07002165), it is stated that STPNOC proposes to reference NEI [Nuclear Energy Institute] 99-03, Revision 0, dated June 2001, in the TS basis for TS 3.7.7, instead of Revision 1, dated March 2003 because the NRC has not formally endorsed Revision 1. The staff understands this to mean that because the NRC has not endorsed Revision 1, STPNOC will not reference this document at any point. However, in Section 6.8.3.p.3, page 3 of 5 of Attachment 2, you identified under item 1) a general exception to Section C of Regulatory Guide (RG) 1.197, Revision 0, by stating that Section 4.3.2 Periodic CRH [Control Room Habitability] Assessment from NEI 99-03 Revision 1 will be used as input to a site specific Self Assessment procedure. Please clarify this inconsistency, keeping in mind that the NRC has neither formally endorsed NEI 99-03, Revision 1 nor has it reviewed this document.
- 2.
In Section 2.2, page 2 of 5 (second paragraph) of Attachment 2, it is stated that [n]o inleakage test is required to determine unfiltered in-leakage from hazardous chemical since this would be a value much less than that currently assumed in the hazardous chemical analyses. Note that NRC RG 1.197 refers to RG 1.78 for guidance on meeting a hazardous chemical challenge. In general, the staff finds it acceptable for licensees to commit to the guidance of RG 1.78 to address hazardous chemical challenges. In the discussion you provided to address chemical hazardous challenges, it is not clear that you are in agreement with the staff position on this issue. Please provide a discussion indicating that your position is consistent with the staff position as outlined in RG 1.78, or provide justification for the differences.
