I.

Offsite Power Source,i The network interconnection between HNP-l and the Southern Company trans-mission system will consist of at least four 230-kV transmission lines which are f ed f rom dif f erent sections of the Southern Company grid. The system shall be able to withstand the simultaneous loss of any system generator and the most critical transmission line associated with its loss.

Separation is provided in routing for these transmission lines as they approach the switchyard.

The 230-kV transmission lines connect to the two startup auxiliary trans-formers (IC and ID). Startup auxiliary transformer 10 normally provides startup and shutdown power. Startuo auxiliary transformer it provides backep power to safety features in the event of the loss of transformer ID. The startup auniliary transformers remain energized to permit auxiliary load transf er if required. Each startup auxiliary transformer, in add-ition to its startup function, is sized to provide 100% of the emergency AC load to engineered safety features within a few seconds following a design basis accident.

The design of the diesel generator systems shall conform to the applicable section of proposed IEEE Standard No. 308. The diesel generators are selected on the basis of their proven reliability and independence as standby power supplies; There are three diesel generator units available for HNP-l (diesel generator IB Will be shared With HNP-2) and each has a 2850-kW continuous rating. The diesel generator units shall not be l

operated in parallel with each other at any time nor do they have any secondary function but shall be utilized solely as a standby power supply, s.

Diesel Fuel tech of the five diesel generators is provided with a storage tank and a day tank. The 13,000 gallons required to be maintained in each of the fuel oil tanks represents a total volume of oil sufficient to operate any four diesel generators at 3250 kW for a period of T days. This is based on a conservative expected fuel consumption of 240 gallons per hour per engine.

The onsite fuel capacity will last longer than the time it would take to replenish the onsite supply f rom of f site sources (which is less than i days).

Valving is available 50 that fuel oil can be transferred between fuel oil storage tanks. However, administrative controls shall be in place to limit long-tenn total diesel generator load to i 13,000 kW, and to limit individual diesel generator loading to 13250 kW.

Two seprate plant batteries shall be furnished, each with its own battery charger. One spare battery charger will be provided as a backup. Each of the two sets of plant batteries has storage capacity to carry the required load for approximately a 2-hour period without recharging. Power from the plant batteries is required under all operating conditions. The maximum requirement-on the batteries is based on a design basis accident at design power with a concurrent loss of AC power.

3/4.8 Et t:CTRICAL POWER SYSTEMS BASES The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems de"ing operation ensures that sufficient power will

.be available to supply the safety related et,ulpment required for (1) the safe shutdown of the facility, and (2) the mitigation and control of accident conditions within the fact 11ty. 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, fach of the five diesel generators is provided with a storage tank and a day tank. The 33,000 gallons required to be maintained in each of the fuel oil tanks represents 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 hour per engire.

The onsite fuel capacity wt)) last lenger 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-ters total diesel generator load to 5 13,000 kW, and to limit individual diesel generator leading to s-3250 LW.

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 rafueling-condition for extended time periods, and (2) sufficient instrumentation and control :apability 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, "5 election 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 Reliabt11ty," July 2, 1984.

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