50-364 Energy to Serve Your World" NL-05-2 127 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D. C. 20555-0001 Joseph M. Farley Nuclear Plant - Unit 2 2B Charging Pump Ladies and Gentlemen:
The purpose of this letter is to document the resolution of the replacement 2B charging pump casing and discharge head discussed during the October 20, October 25, and October 3 1, 2005 conference calls between Southern Nuclear Operating Company (SNC) and the Nuclear Regulatory Commission (NRC) Staff.
A replacement pump casing and discharge head, originally designated and "N" stamped per ASME Section I11 for Code Class 2 service, had not been continuously controlled as safety related ASME Code Class 2 parts since 1984 per the storage requirements of 10 CFR 50 Appendix B. Thus, the original as-built ASME Section I11 level of quality had to be evaluated before the pump casing and discharge head could be used asSection XI replacements.
During the October 20 and 25,2005 conference calls, three methods were discussed to disposition the questions related to storage and control of these parts, which would allow returning the 2B charging pump to service during the 2R17 refueling outage. The initial method was to obtain NRC approval of an alternative to ASME Section XI. Based on discussions during these conference calls, SNC determined that requesting NRC approval of an alternative to Section XI would not be appropriate. The second method was for SNC to disposition this issue within the SNC corrective action program and return the 2B charging pump to service. Also, use of Generic Letter 89-09 was considered as a third method for SNC to disposition this issue. SNC has determined that the appropriate process to disposition this issue and return the 2B charging pump to service is for SNC to document the pump casing and discharge head acceptability within the corrective action program.
The status and proposed disposition of this issue was again discussed during an October 31,2005 conference call between SNC and the NRC (NRR and Region 11) Staff. The installation of the replacement pump casing and discharge head replacement has been implemented with a design change. The 2B charging pump is considered operable and has been returned to service.
