SUBJECT:

10CFR21-0037 Notification EMD Model 999 Excitation System Circuit Breaker and Wiring HK/PSD Report No. 10CFR21-0037-1 Gentlemen:

Power Systems Division of Morrison-Knudsen Company received a phone call from Mr. Ed Freeman of the TVA-Browns Ferry Nuclear Plant on 1/25/S8.

He reported that the generator field breaker tripped open during a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> load test while the diesel generator was carrying 2950 KW @ 0.8 P.F.

The field circuit breaker is a General F?ectric size 100 amp, type TED 136100 which has a 5% to 10% r.argin.

It is located in the generator control panel and in the circuit as shown in the subject report.

Since only the Browns Ferry diesel generators had the G.E. circuit breakers, it was thought the problem may be limited to the Browns Ferry plant.

However, after corrective action was completed by Browns Ferry, they conducted a test to record temperatures inside the generator cabinet.

The results indicated that the air temper-atures around the field circuit could exceed 5000 at loado of 2850 KW and 0.8 P.F. which may cause the field breaker to trip at a lower amperage during an extended run period.

n.

l 10CFR21-0037 Notification October 5, 1988 Page Two Since all Hodel 999 generator control panels are basically the same design and construction, the potential for the field circuit breaker to trip due to combined air temperatures and L

field current exists at all nuclear piknts which have the 4

model 999 system.

L Therefore, the recommendations in MK/PSD Report No. 10CFR21-0037-1 could be applicable to other nuclear power plants with l

the EMD 999 diesel generator system.
