VEGP-FSAR-Q (NRC) and from the NRC to Georgia Power Company, etc., will be implemented as follows:

A. The remote shutdown preoperational test abstract (paragraph 14.2.8.1.105) has been revised to include simulating a loss of ac power sources and operating the plant using manual control and the steam-driven auxiliary feedwater pump. , 9 B. The low power natural circulation test abstract (paragraph 14.2.8.2.47) has been revised to include the detail of item 3 of the above referenced letter.

l15 C. The loss of offsite power at greater than 10 percent power test abstract (paragraph 14.2.8.2.46) has been revised to reflect that the plant can be maintained in a stable condition on natural circulation using the batteries and diesels.

D. Each licensed reactor operator (RO or SRO who performs RO or SRO duties, respectfully) will participate in the initiation, maintenance, and recovery from the natural circulation mode on the simulator.

E. The pressuriner heater and spray verification test abstract (paragraph 14.2.8.2.2) has been revised to include the detail of item 2 of the above-referenced letter. The test will also provide data to verify 15 simulator modeling. After this, each licensed reactor operator not present during the test performance will receive simulator training.

Revise item 0 to read:

"D. Each licensed reactor operator (R0 or SR0 who performs R0 or SR0 duties, respectively) will participate in the initiation, maintenance, and recovery from natural circulation during the low power natural circulation test or receive training on the simulator."

Amend. 8 7/84 Amend. 9 8/84 Q640.04-2 Amend. 15 3/85 l

Q640.20 Response:

Testing will be performed to demonstrate that each class 1E DC inverter, motor-operated valve, and solenoid-operated valve would receive adequate operating voltage if its respective battery were operating at the low voltage limit. The voltage drop for each of these feeders will be determined by measuring voltage as near as practicable to the component, while operating under load, and subtracting from prevailing nominal battery voltage. The resulting voltage drop will then be subtracted from the battery low voltage limit to demonstrate that available component operating voltage would be within its design range if the battery were discharged to this voltage without the availability of a battery charger. Each distribution air circuit breaker which receives control power from the class 1E DC systems is separately tested during construction acceptance testing to demonstrate operability at minimum specified operating voltage (see test abstract 14.2.8.1.113).
