3/4.8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.1 and 3/4.8.2 A.C. SOURCES and ONSITE POWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety related equipment required for (1) the safe shutdown of the facility and (2) the mitigation and control of accident conditions within the facility. The minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix A to 10 CFR Part 50.

The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon cortinued facility operation commensurate with the level of degradation. ACTION statements have been included in the specification to cover all situations where either one A.C.

source or a combination of two A.C. sources are inoperable. ACTION statements c, e, and f are intended to be followed to completion once entered and should not be exited until both A.C. sources are restored. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based u m n maintaining at least Division I or II of the onsite A.C. and 0.C. power soneces and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of one of the two onsite A.C. sources. Division III supplies the high pressure core spray (HPCS) system only.

The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that (1) the facility can be maintained in the shutdown'or refueling condition for extended time periods and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.

The surveillance requirements for demonstrating the OPERABILITY of the diesel generators are based on the recommendations of Regulatory Guide 1.9, Revision 3, " Selection, Design, Qualification, and Testing of Emergency Diesel Generator Units Used as Class IE Onsite Electric Power Systems at Nuclear Power Plants," July 1993, with the exception noted in Appendix B to the UFSAR.

The tests listed below are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an immediate, detrimental impact on diesel engine combustion / operation.

If results from these tests are within acceptable limits, the fuel oil may be added to the storage tanks without concern for contaminating the entire volume of fuel oil in the storage tanks. The tests, limits, and applicable American Society for Testing Materials (ASTM) standards are as follows:

a.

Sample the new fuel oil in accordance with ASTM-D4057-88; b.

Verify in accordance with the tests specified in ASTM-D975-88 that the sample has a water and sediment content of less than or equal to 0.05 volume percent and a kinematic viscosity at 40 *C of greater than or equal to 1.9 but less than or equal to 4.1.

3/4.8.1 and 3/4.8.2 A.C. SOURCES and ONSITE POWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. power sources and associated l

distribution systems during operation ensures that sufficient power will be i

available to supply the safety related equipment required for (1) the safe i

shutdown of the facility and (2) the mitigation and control of accident conditions within the fr.cility. The minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix A to 10 CFR Part 50.

The ACTION requirements specified for the levels of degradation of the i

power sources provide restriction upon continued facility operation commensurate with the level of degradation. ACTION statements have been 2

included in the specification to cover all situations where either one A.C.

. source or a combination of two A.C. sources are inoperable. ACTION statements c, e, and f are intended to be followed to completion once entered and should i

not be exited until both A.C. sources are restored. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the i

accident analyses and are based upon maintaining at least Division I or II of the onsite A.C. and D.C. power sources and associated distribution systems l

OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of one of the two onsite A.C. sources. Division III 4

y supplies the high pressure core spray (HPCS) system only.

i The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that (1) the facility can be maintained in the shutdown or refueling condition for exterted time periods and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.

The surveillance requirements for demonstrating the OPERABILITY of the diesel generators are based on the recommendations of Regulatory Guide 1.9, Revision 3, " Selection, Design, Qualification, and Testing of Emergency Diesel 1

Generator Units Used as Class IE Onsite Electric Power Systems at Nuclear Power Plants," July 1983, with the exception noted in Appendix B to the UFSAR.

The tests listed below are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an immediate, detri:aental impact on diesel engine combustion / operation.

If results from these tests are within acceptable limits, the fuel oil may be added to the storage tanks without concern for contaminating the entire volume of fuel oil in the storage tanks. The tests, limits, and applicable American Society for Testing Materials (ASTM) standards are as fo11cws:

a.

Sample the new fuel oil in accordance with ASTM-D4057-88; b.

Verify in accordance with the tests specified in ASTM-D975-88 that the sample has a water and sediment content of less than or equal to 0.05 volume percent and a kinematic viscosity at 40 'C of greater than or equal to 1.9 but less than or equal to 4.1.
