REQUEST FOR ADDITIONAL INFORMATION REGARDING BULLETIN 2003-01, "POTENTIAL IMPACT OF DEBRIS BLOCKAGE ON EMERGENCY SUMP RECIRCULATION AT PRESSURIZED WATER REACTORS" SEABROOK STATION, UNIT NO. 1 DOCKET NO. 50-443 By letter dated August 8, 2003, FPL Energy Seabrook, LLC (FPLE or the licensee) responded to NRC Bulletin 2003-01, "Potential Impact of Debris Blockage on Emergency Sump Recirculation at Pressurized-Water Reactors," for Seabrook Station, Unit No. 1 (Seabrook).

During the course of review of the licensees bulletin response, the Nuclear Regulatory Commission staff has determined that it needs the following information:

1. In response to Bulletin 2003-01, the licensee listed a number of existing indications that could indicate the onset of sump blockage, existing operator guidance documents relating to monitoring for sump blockage (e.g. pump motor current, pump flow rate, and pump discharge pressure), and enhanced training for operators and engineering support personnel on the issue of containment sump clogging. However, the licensee's response does not completely discuss the operator training to be implemented; in that, they do not discuss the existing response actions the operators are instructed to take in the event of sump clogging and loss of emergency core cooling systems (ECCS) recirculation capability. Provide a detailed description of how the current emergency operating procedures address sump clogging and a loss of ECCS recirculation capability.

2. The Westinghouse Owners Group (WOG) has developed operational guidance in response to Bulletin 2003-01 for Westinghouse and Combustion Engineering type pressurized water reactors. For Seabrook, the licensees response stated that they will monitor the WOG activities and will consider implementation of any issued guidance.

Provide a discussion of the WOG-recommended compensatory measures that have been or will be implemented for the plants. Include a discussion of the evaluations or analyses performed to determine that these compensatory measures are acceptable for Seabrook, and provide technical justification for those WOG compensatory measures not being implemented. Also include a detailed discussion of the procedures being modified, the operator training being implemented, and the schedule for implementing these compensatory measures.

3. NRC Bulletin 2003-01 provides possible interim compensatory measures licensees could consider to reduce risks associated with sump clogging. In addition to those compensatory measures listed in Bulletin 2003-01, licensees may also consider implementing unique or plant-specific compensatory measures, as applicable. Discuss any possible unique or plant-specific compensatory measures that were considered for implementation at Seabrook. Include a basis for rejecting any of these additional measures considered.
