NRC REPORT 50-335/88-16

DEVIATION The Uni:t 1 FSAR, Section 8.3.1.1.7, requires the diesel generators

to be capable of reaching full speed and voltage within 10 seconds after receiving a signal to start.Contrary to the above, during Unit 1 emergency diesel generator surveillance

testing on March 29, 1987, emergency diesel generators

1A and 1B attained rated speed and voltage in 10.1 seconds and 12.7 seconds, respectively.

As such, Unit 1 surveillance

testing on two occasions failed to demonstrate

the diesel generators

are capable of satisfying

FSAR design requirements.

RESPONSE 1.Reason for deviation:

FPL has investigated

this deviation with the operators involved.Because of the time lapse (greater than 15 months), no specific reasons could be given as to why they would have entered start times for the diesels in excess of the design values and not have notified the responsible

supervision.

Subsequent

entries in the same data sheet are within the design values and records of maintenance

activities

show no conclusive

evidence that start times were affected.In addition, the diesels were tested as part of the integrated

response time tests for safeguards

equipment in July and found to be satisfactory.

2.Corrective

steps: Since the diesels had met the design start times subsequent

to the dates identified, no immediate action was taken.3.Corrective

steps to preclude further deviation:

FPL has changed the monthly diesel periodic test to require the design start time be verified within specifications.

In addition, the responsible

personnel have been instructed

to notify the operations

supervisor

in instances where surveillances

are satisfactory

but the equipment is known not to meet its design requirements.

4.Corrective

action is considered

complete.
