REQUESTS FOR ADDITIONAL INFORMATION Point Beach Nuclear Plant (PBNP), Units 1 and 2 License Amendment Request (LAR-264) dated January 27, 2010 Diesel Fuel Oil Storage Requirements (TAC Nos. ME3282 and ME3283)
The following requests for additional information are associated with the NRC staff review of LAR-264 associated with diesel fuel oil storage requirements for the PBNP, Units 1 and 2.
EEEB-1 The Nuclear Regulatory Commission Staff has reviewed past correspondence related to the licensing basis for emergency diesel generator (EDG) fuel oil requirements. The staff considers that the onsite fuel oil storage shall be sufficient to operate the diesel generator following any design basis event for seven days. The current license amendment request (264) addresses the most limiting condition of operation of two EDGs operating for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> versus one EDG operating for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
Please provide a detailed discussion explaining why the seven day fuel requirement, as discussed in the licensing basis documents, is not factored into the TS controlled bounding fuel oil volume requirements.
EEEB-2 Several tanks are credited for fuel oil storage requirements.
Please provide details on procedures used to verify the flow paths from each tank dedicated to the corresponding EDG for demonstration of storage capacity.
