3/4.8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.1 and 3/4.8.2 A.C.

SOURCES AND ONSITE POWER DISTRIBUTION SYSTEME 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 criterion 17 of Appendix "A" to 10 CFR Part 50.

l The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least two independent sets of g

onsite A.C.

and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite l

power and single failure of one onsite A.C.

source.

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.

l The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are based upon the recommendations of Regulatory Guide 1.9,

" Selection of Diesel Generator Set Capacity for Standby Power Supplies,"

March 10, 1971, and negulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977.

For the purposes of establishing initial conditions for surveillance testing, " ambient conditions" mean that the diesel lube oil temperature is 120 1 20 degrees F.

The minimum lube oil temperature for an OPERABLE diesel is 100 degrees F.

Lube oil heaters are designed to maintain the mil temperature at approximately 120 degrees F.

3/4.8.3 ELECTRICAL EOUIPMENT PROTECTIVE DEVICES 5

Containment electrical penetrations and penetration conductors are protected by either deenergizing circuits not required during reactor operation or by demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers during periodic surveillance.

The surveillance frequency applicable to molded case circuit breakers and lower voltage circuit breakers provides assurance of breaker reliability by i

testing at least one representative sample of each manufacturer's brand of molded case and lower voltage circuit breakers. Each manufacturer's molded SALEM - UNIT 1 B 3/4 8-1 Amendment No.

148 l

r

o 3/4.8 ELECTRICAL POWER SYSTEMS BASES (Continued) case circuit breakers and lower voltage circuit breakers are grouped into representative samples which are then tested on a rotating basis to ensure that all breakers are tested.

If a wide variety exists within any l

manufacturer's brand of molded case or lower voltage circuit breakers, it is necessary to further divide that manufacturer's breakers into groups and treat each group as a separate type of breaker for surveillance purposes.

i A list of the required containment penetration conductor overcurrent 3

protective devices, with information on location, size and equipment powered by the protective circuit is maintained in the UFSAR.

The list is limited to those overcurrent devices installed for the purpose of keeping circuit fault current below the penetration rating.

It does not apply to other overcurrent devices which protect penetrations where fault currents are less than the sustained rating of the penetration. This is consistent with the requirements of IEEE 741-1986 which states that no special consideration is required to protect electrical penetrations that can indefinitely withstand the maximum fault current available.

Setpoints are controlled by plant procedures and drawings and any additions, deletions or modifications to the containment penetration conductor overcurrent protective devices list'is governed by Section 50.59 of 10 CFR Part 50.

3/4.8 ELECTRICAL POWER SYSTEMS BASES

==================================================================

.t 3/4.8.1 AND 3/4.8.2 A.C.

SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C.

-nd 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 Criterion 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 continued facility operation commensurate with the level of degradation.

The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least two independent sets of l

onsite A.C.

and D.C.

power sources and associated distribution systems OPUtABLE during accident conditions coincident with an assumed loss of offsite l

power and single failure of one onsite A.C. source.

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 upon the recommendations of Regulatory Guide 1.9, l

" Selection of Diesel Generator Set Capacity for Standby Power Supplies,"

March 10, 1971, and Regulatory Guide 1.108, " Periodic Testing of Diesel l

Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977.

For the purposes of establishing initial conditions for surveillance testing, " ambient conditions" mean that the diesel lube oil temperature is 120 1 20 degrees F.

The minimum lube oil temperature for an OPERABLE diesel is 100 degrees F.

Lube oil heaters are designed to maintain the oil temperature at approximately 120 degrees F.

3/4.8.3 ELECTRICAL EOUIPMENT PROTECTIVE DEVICES Containment electrical penetrations and penetration conductors are protected by either deenergizing circuits not required during reactor operation or by demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers during periodic surveillance.

The surveillance frequency applicable to molded case circuit breakers and lower voltage circuit breakers provides assurance of breaker reliability by testing at least one representative sample of each manufacturer's brand of molded case and lower voltage circuit breakers.

Each manufacturer's molded SALEM - UNIT 2 B 3/4 8-1 Amendment No.

126 i

ELECTRICAL POWER SYSTEMS BASES (Continued) case circuit breakers and lower voltage circuit breakers are grouped into representative samples which are then tested on a rotating basis to ensure that all breakers are tested.

If a wide variety exists within any manufacturer's brand of molded case or lower voltage circuit breakers, it is necessary to further divide that manufacturer's breakers into groups and treat each group as a separate type of breaker for surveillance purposes.

A list of the required containment penetration conductor overcurrent protective devices, with information on location, size and equipment powered by the protective circuit is maintained in the UFSAR.

The list is limited to those overcurrent devices installed for the purpose of keeping circuit fault current below the penetration rating.

It does not apply to other overcurrent devices which protect penstrations where fault currents are less than the sustained rating of the penetration. This is consistent with the requirements of IEEE 741-1986 which states that no special consideration is required to protect electrical penetrations that can indefinitely withstand the maximum fault current available. Setpoints are controlled by plant procedures and drawings and any additions, deletions or modifications to the containment penetration conductor overcurrent protective devices list is governed by Section 50.59 of 10 CFR Part 50.
