Subject:
Additional Information Supporting the Request for Amendment to Technical Specifications Associated With Direct Current Electrical Power
References:
(1) Letter from P. R. Simpson (Exelon Generation Company, LLC) to U. S. NRC, "Request for Amendment to Technical Specifications Associated With Direct Current Electrical Power," dated July 29, 2003 (2) Technical Specifications Task Force (TSTF) Traveler TSTF-360, Revision 1, "DC Electrical Rewrite" In Reference 1, Exelon Generation Company, LLC (EGC) requested an amendment to the facility operating licenses for Dresden Nuclear Power Station, Units 2 and 3. The proposed changes modify Technical Specifications (TS) Sections 3.8.4, "DC Sources - Operating,"
3.8.5, "DC Sources - Shutdown," 3.8.6, "Battery Cell Parameters," and 5.5, "Programs and Manuals," to be consistent with Reference 2.
In a conference call with the NRC on January 8, 2004, the NRC requested EGC to provide diagrams of the 125 VDC and 250 VDC systems. The requested information is attached.
EGC has reviewed the information supporting a finding of no significant hazards consideration that was previously provided to the NRC in Attachment 1 of Reference 1. The supplemental information provided in this submittal does not affect the bases for concluding that the proposed license amendment does not involve a significant hazards consideration.
