SUMMARY

OF MEETING HELD TO DISCUSS RETEST!NG 0F $!MULATOR RESPONSE On May 8,1985, the staff met with the applicant to discuss the retesting of simulator response in line with Regulatory Guide 1.149, " Nuclear Power Plant Simulators for Use in Operator Training." Enclosure 1 lists the participants.

The apolicant gave a presentation to the staff regarding the process it employs to ensure that its simulator is up to date. The presentation outline is provided in Enclosure 2. In its presentation, the applicant stated that it collects actual plant data and compares it to simulator data during training conducted on the simulator. The applicant diso stated that operators report discrepancies between the plant and simulator. The applicant comited, as part of the simulator updating process, to evaluate changes in procedures and to systematically in-corporate these changes into the simulator data base. Each time the simulator data base is changed, the applicant stated that it would retest the simulator under normal, accident and loss of coolant accident conditions.

The staff clarified that the applicant's reference in the FSAR to annual perfor-mance testing should actually be performance testing every 4 years.

The applicant further indicated that verifying over 200 malfunctions to conform with Regulatory Guide 1.149 would present a problem since not all of these analyses are done on the plant.

The staf f indicated several problems with the applicant's approach. First, no provision has been made for actual documentation of performing the test, its results, and the evaluation of results. Second, testing has not been differen-tiated from training indicating an informal approach to performance testing.

Also, the applicant s approach does not detail how the sinulator's data base would be systematically reviewed against the complete data base of the plant.

In general, the applicant's method is not strict enough. The staff indicated that the applicant's proposed program of simulator testing does not appear to meet the intent of Regulatory Guido 1.149.

V0GTLE SIMULATOR QUALIFICATION PLAN PURPOSE This report underscores the determination of Georgia Power Company to implement the most effective, quality nuclear training possible. This includes use of accurate full scope simulators at both nuclear sites.

BACKGROUND Georgia Power Company realized early the value of strong, effective training programs for ensuring acceptable qualifications of nuclear plant personnel. As early as 1978 (pre-TMI) Georgia Power Company started work on substantially upgrading the effectiveness of nuclear training. Full scope simulators were ordered for the Hatch and Vogtle facilities and construction of new elaborate training centers was begun. This commitment to excellence will continue as we finish construction of Plant Vogtle and put the plant into operation.

VEGP SIMULATOR s

• ANSI 3.5 qualified to design data base at time of delivery by completion of a detailed factory acceptance test.

• Will be matched to plant by:

1. Physical panel comparison at or near fuel load.

2. Comparison to plant startup data.

3. Comparison to best estimate of transient and accident response.

Feedback from experienced staff members will be collected and evaluated.

Changes will be made to the simulator and retesting completed at the time t of each change.

4. Simulator performance testing Performance testing is conducted shall be conducted not less than continuously during training scenarios every four (4) years, and following any changes which are made to the simulator. This specific in use testing provides more immediate updating of simulator performance than general testing every four years.

Additionally, since training scenarios are repeated more frequently and with a greater degree of variation, a much wider scope of testing results.

SUMMARY

Georgia Power Company is commited to high quality training which includes the use of full scope simulators at both nuclear sites. Many more simulator exercises are performed during training than during a performance test.

Continuous feedback collection coupled with plant change review is a better way to ensure simulator fidelity. Periodic performance retesting is redundant and would not contribute to improved simulator fidelity.
