BASES FOR SURVEILLANCE REQUIREMENTS 4.9.
AUXILIARY ELECTRICAL SYSTEMS A.
Auxiliary Electrical Systems Eautomnt The auxiliary electrical power systems shall be functionally tested and in-spected at a frequency to assure a high reliability of operation and a high degree of perfonnance. This surveillance program is designed to meet the intent of " Proposed IEEE Criteria for Class lE Electric Systems for Nuclear Power Generating Stations (Standard No, 308).
- a. Operability Upon demand, the standby diesel generators shall start automatically and
)
j reach rated frequency and voltage within 12 seconds (unloaded). Based on the operation of all diesel generation units and all amenjency buses, the diesel generators are capable of accepting all AC loads within 40 seconds. Since the diesel generators aie utilized as standby power sources, readiness is of prine igortance. Readiness can best be demon-strated by testing, which insofar as practicable sinalates actual ear-gency conditions. The testing program is designed to test both the ability to start and the ability to run the diesel generators under load for extended
. periods of operation.
Each diesel generator unit is furnished with two cogletely independent air starting systems, either of which is capable of starting the diesel engine five times without recharging.
The monthly test of the diesel generators is conducted to check for equip-ment failures and deterioration. Testing is conducted until the diesels reach equilibrita operating conditions to demonstrate proper operation of these conditions. Each diesel shall be manually started, synchronized to the
.I bus, and load picked up. The diesels shall be loaded to at least one-half rated load to prevent fouling of the engines. The diesel generators will nonnally be run for at least one hour. In addition, during the test l
when the generator is synchronized to the bus, it is also synchronized to the offsite power source and thus is not cogletely independent of this source. Only one diesel shall be tested at a time to prevent parallel operation with another.
The hot start test is performed on each diesel generator every 18 months. This surveillance damnstrates that the diesel engine can restart frun a hot condition, such as subsequent to shutdow) from normal surveillances, and achieve the required voltage and frequency within 12 seconds. The 12 second time is derived from the requirerrents of the accident analysis. The 18 month frequency is consistent with the reconnendations of Regulatory Guide 1.108. The requirement that the diesel has operated for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at near full load conditions prior to performance of this surveillance is based on manufacturer recomnendations for achieving hot conditions. Momentary transients due to changing bus loads do not invalidate this test, b.
Qiesel Battery (125 Volt)

- 10. Verifying that the auto-connected loads to each diesel generator do not exceed the 2000-hour rating of 3100 kW.
- 11. Verifying the diesel generator's capability to:
a)
Synchronize with the offsite power source while the generator is loaded with its emergency loads upon a simulated restoration of offsite power, b) Transfer its loads to the offsite power source, and c)
Proceed through its shutdown sequence.
- 12. Verifying that with the diesel generator operating in a test mode (connected to its bus), a simulated LOCA actuation signal overrides the test mode by:
(1) returning the diesel generator to standby operation and (2) auto-matically energizes the emergency loads with offsite power.
- 13. Verifying that the fuel transfer pump transfers fuel from each associated fuel storage tank to the day tank of each diesel via the installed cross connection lines.
- 14. Operating each diesel generator for 2 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> loaded 2 2565 kW',
and within 5 minutes of shutting down the diesel generator following this run, it shall be verified the diesel generator starts and achieves, in s 12 seconds, voltage 2 3740 V and l
5 4580 V, and frequency 2 58.8 Hz and s 61.2 Hz."'
- Momentary variations outside this band shall not invalidate the test.
" For the 18 diesel generator, a single 24-hour load test every 18 months will satisfy the requirements of Unit 1 Specification 4.9.A.2.a.6 and Unit 2 Specification 4.8.1.1.2.d.9.
For the 18 diesel generator, a single hot start test every 18 months will satisfy the requirements of Unit 1 Specification 4.9 A.2.a.ll and Unit 2 Specification 4.8.1.1.2.d.14.

3/4,8 ELECTRICAL POWER SYSTEMS S_ASES 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 i
accident conditions within the facility.
The minimum specified indepen-dent 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 one of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of the other onsite A.C. source.
Each of the five diesel generators is provided with a storage tank and a day tank. The 33 the fuel oil tanks repre,000 gallons required to be maintained in each of sents a total volume of oil sufficient to operate any four diesel generators at 3250 kW for a period of 7 days.
This is based on a conservative expected fuel consumption of 240 gallons per i
hour per engine.
The onsite fuel capacity will last lonqer than the time it would take to replenish the onsite supply from offsite sources (which is
< 7 days).
Valving is available so that fuel oil can be transferred between fuel oil storage tanks.
However, administrative controls shall be in place to limit long-term total diesel generator load to s 13,000 kW, and to limit individual diesel generator loading to 5 3250 kW.
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 facility status.
The surveillance requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regula-tory Guide 1.9, " Selection of Diesel Generator Set Capacity for Standby Power Supplies," March 10, 1971, Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977, and Generic Letter 84-15, " Proposed Staff Actions to Improve and Maintain Diesel Generator Reliability," July 2, 1984.
The hot start test specified in Regulatory Guide 1.108 has been modified to separate this test from the loss of offsite power functional test and the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> load test.
The modified hot start test conforms to the BWR 4 Standard Technical Specifications, NUREG-1433.
The hot start test HATCH - UNIT 2 B 3/4 8-1 Amerldment No.131
3/4.8 ELECTRICAL POWER SYSTEMS BASES is performed on each diesel generator every 18 months.
This surveillance demonstrates that the diesel engine can restart from a hot condition, such as subsequent to shutdown from normal surveillances, and achieve the required voltage and frequency within 12 seconds.
The 12 second time is derived from the requirements of the accident analysis.
The 18 month frequency is consistent with the recommendations of Regulatory Guide 1.108.
The requirement that the diesel has operated for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at near full load conditions prior to performance of this surveillance is based on manufacturer recommendations for achieving hot conditions. Momentary transients due to changing bus loads do not invalidate this test.
Primary containment electrical penetrations and penetration conductors are protected by either de-energizing circuits not renuired during reactor operation or demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers by periodic surveillance.
