| the Nuclear Regulatory Commission staff has determined that the following information is needed in order to complete its review:1.Confirm the short time rating of the EDGs considering the definition of "short-time rating"in Institute of Electrical and Electronics Engineers (IEEE) Standard 387. Provide the necessary documentation and/or basis which confirms this short-time rating.2.Provide the licensing and design basis history for EDG rating and testing. Confirm allapplicable guidance, such as regulatory guides (RGs) and IEEE standards, including which revisions of, and the exceptions taken to that guidance, that KPS has committed to regarding EDG rating and testing. Provide the docketed correspondence (or references thereto) in which these commitments were made. In particular, specify the revisions of IEEE 387 and RG 1.9 to which the plant was originally licensed and the revisions to which KPS is now committing for the purpose of EDG sizing and testing.3.Provide the most current (and QA-approved/accepted) calculation (based on the worst-case accident analyses) of the EDG load profile for the first 24 hours of a design-basis accident (DBA) and subsequent safe shutdown.4.Explain how the proposed testing in the license amendment request will verify that theEDGs are capable of meeting the wort-case load profile for 24 hours. In addition, since the loads indicated in the KPS updated final safety analysis report appear to exceed the EDG's continuous rating, explain how the proposed testing meets the intent of Revision 3 of RG 1.9.5.Provide the calculation and vendor manual (or guidance) that explains how temperatureaffects the rating and the operation of the EDGs. Provide the necessary calculation of the derating factors which would be applied to various EDG ratings, especially the continuous and short-time ratings, considering the maximum assumed outside temperature. Considering these derating factors, provide the corresponding EDG ratings. In addition, page 13 of KPS's license amendment request states, "A calculation performed by KPS staff has shown that the EDGs can be loaded to 2864 kW with an outside air temperature of 97.8 F without requiring de-rate." Provide this calculation if itdiffers from the above requested calculation. 6.Provide justification that the EDGs will be able to perform their design function during aDBA and subsequent shutdown of the reactor assuming the worst-case derating due to an outside temperature that results in derating the EDG. 7.Your letter dated January 10, 2007, stated that the KPS EDG engine coolant outlettemperature is limited to less than 190 °F. Provide the calculation or vendor manual (or guidance) that explains how the coolant outlet temperature is limited to less than 190 °F. 8.Your letter dated January 10, 2007, stated that calculations have shown that thedifference between outside air temperature and diesel engine room temperature is approximately 15 °F to 20 °F during the summer months.

REQUEST FOR ADDITIONAL INFORMATION KEWUANEE POWER STATION DOCKET NO. 50-305 In reviewing the Dominion Energy Kewuanee, Inc.s submittal dated January 10, 2007, related to emergency diesel generator short-time load testing, for the Kewuanee Power Station (KPS),
the Nuclear Regulatory Commission staff has determined that the following information is needed in order to complete its review:
- 1. Confirm the short time rating of the EDGs considering the definition of short-time rating in Institute of Electrical and Electronics Engineers (IEEE) Standard 387. Provide the necessary documentation and/or basis which confirms this short-time rating.
- 2. Provide the licensing and design basis history for EDG rating and testing. Confirm all applicable guidance, such as regulatory guides (RGs) and IEEE standards, including which revisions of, and the exceptions taken to that guidance, that KPS has committed to regarding EDG rating and testing. Provide the docketed correspondence (or references thereto) in which these commitments were made. In particular, specify the revisions of IEEE 387 and RG 1.9 to which the plant was originally licensed and the revisions to which KPS is now committing for the purpose of EDG sizing and testing.
- 3. Provide the most current (and QA-approved/accepted) calculation (based on the worst-case accident analyses) of the EDG load profile for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of a design-basis accident (DBA) and subsequent safe shutdown.
- 4. Explain how the proposed testing in the license amendment request will verify that the EDGs are capable of meeting the wort-case load profile for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. In addition, since the loads indicated in the KPS updated final safety analysis report appear to exceed the EDGs continuous rating, explain how the proposed testing meets the intent of Revision 3 of RG 1.9.
- 5. Provide the calculation and vendor manual (or guidance) that explains how temperature affects the rating and the operation of the EDGs. Provide the necessary calculation of the derating factors which would be applied to various EDG ratings, especially the continuous and short-time ratings, considering the maximum assumed outside temperature. Considering these derating factors, provide the corresponding EDG ratings. In addition, page 13 of KPSs license amendment request states, A calculation performed by KPS staff has shown that the EDGs can be loaded to 2864 kW with an outside air temperature of 97.8 EF without requiring de-rate. Provide this calculation if it differs from the above requested calculation.
- 6. Provide justification that the EDGs will be able to perform their design function during a DBA and subsequent shutdown of the reactor assuming the worst-case derating due to an outside temperature that results in derating the EDG.
ENCLOSURE
- 7. Your letter dated January 10, 2007, stated that the KPS EDG engine coolant outlet temperature is limited to less than 190 °F. Provide the calculation or vendor manual (or guidance) that explains how the coolant outlet temperature is limited to less than 190 °F.
- 8. Your letter dated January 10, 2007, stated that calculations have shown that the difference between outside air temperature and diesel engine room temperature is approximately 15 °F to 20 °F during the summer months. Provide these calculations.
