NuEl Committed to Nuclear &xcelenf" Point Beach Nuclear Plant Operated by Nuclear Management Company, LLC NRC 2003-0056 June 10, 2003 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 DOCKET 50-301; LICENSE NO. DPR-27 POINT BEACH NUCLEAR PLANT, UNIT 2 SUBMITTAL OF THE AUXILIARY FEEDWATER ORIFICE ISSUE REGULATORY CONFERENCE SLIDE PRESENTATION Ladies/Gentlemen:
On June 6, 2003, a regulatory conference was conducted between representatives of the Nuclear Management Company, LLC (NMC) and members of your Staff to discuss the Auxiliary Feedwater Orifice Issue at Point Beach Nuclear Plant (PBNP). During the presentation, a question was raised regarding the installation date, shown on slide eight, of the "A" motor driven auxiliary feedwater pump recirculation line orifice. A review perfonned following the conference determined that the date presented was incorrect and should have reflected a November 2000 installation date. This error did not impact the risk analysis discussed at the conference.
The attached slide presentation is provided for your use. Based on the error identified above, three slides; eight, twenty, and twenty-one have been corrected. Additionally, slide eight has been clarified to reflect the "A" and "B" designation of the motor driven auxiliary feedwater pumps.
If you have any questions, please contact Gordon P. Arent at 920/755-6518.

Potential for Fouling of Recirculation Line Coincident with Procedurally-Directed Operator Action to Secure AFW Forward Flow.
> Identified by NMC Following System Testing of the Motor Driven AFW Pump
> Orifice Plugging Could Occur When AFW Pumps Were Aligned to Service Water Resulting in Potential Common Mode Failure
> Prompt Corrective Actions
- All Four AFW Pumps Declared Out-of-Service Due to Potential Recirculation Orifice Common Mode Failure
- Compensatory Actions Established to Direct Operators to Secure AFW Pumps in the Event Minimum Recirculation Flow Cannot be Maintained 9
