Come lNubeerExce Palisades Nuclear Plant Operated by Nuclear Management Company, LLC August 13, 2003 U S Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 PALISADES NUCLEAR PLANT DOCKET 50-255 LICENSE No. DPR-20 CLARIFICATION TO THE NUCLEAR REGULATORY COMMISSION BULLETIN
-2003-OPOTENALMPCTIUVF1EBRISOCKAGE EMERGENCY SUP -
RECIRCULATION AT PRESSURIZED-WATER REACTORS DAY RESPONSE By letter dated August 5, 2003, Nuclear Management Company, LLC (NMC) provided the 60-day response to the Nuclear Regulatory Commission (NRC)
Bulletin (BL) 2003-01, Potential Impact of Debris Blockage on Emergency Sump Recirculation at Pressurized-Water Reactors."
NMC is providing a clarification to the Palisades BL 2003-01 response. A minor error was discovered in the first paragraph on the top of page 4 of the attachment. The paragraph read, as follows:
Implementation Schedule: Preliminary assessment by NMC, in consultation with the Westinghouse Owners Group (WOG), indicates that this change, with regards to securing high pressure safety injection (HPSI) and low pressure safety injection (LPSI) pumps prior to recirculation, may have an adverse effect on plant safety by substituting manual actions for existing automatic actions. These automatic actions introduce a potential for a single active failure vulnerability."

This letter contains no new commitments.
