SUPPLEMENTAL INFORMATION TO AMENDMENT REQUEST INCREASED VOLTAGE LIMIT FOR IDAD REJECTION TEST FACILITY OPERATING LICENSE NPF-57 IlOPE CREEK GENERATING STATION DOCKET NO. 50-354 This letter is in response to a question posed by the NRC review staff concerning License Change Request 91-03 for the Hope Creek Generating Station. The question pertained to the effect on the generator and components upstream of the diesel generator output breaker that will be subjected to a momentary voltage increase that could be as high as 15% above nominal during the performance of the full load rejection test.

The voltage spike that occurs during the voltage regulator response following the fu.11 load rejecticn has 'c uen evaluated and will have negligible effecu on the generatcr or any of the components, (eg., relays, meters, voltage regulator, transformers, etc. ) , that are upstream of the g merator output breaker. The service life of these components will not be decreased as a result of performing this test every 18 months.

If you have any further questions, please call S. Mannon (609) 339-1129, of my staff.
