.O NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE JULY 1983 At the onset of the July 1983 reporting period, power generation was continuing at 93% Reactor Rated Thermal Power (41 MWe-Net).
On July 9, a manual reactor shutdown was conducted due to failure of a Type B leakage test on the personnel airlock. This event was discussed in Reportable Occurrence No. 83-05. The reactor was taken critical at 0445 on July 10, but a spurious spike on Nuclear Instrumentation Ch. 5 resulted in an automatic shutdown at 0506. The reactor was returned to critical at 0941 on July 10 and the turbine-generator was synchronized to the DPC grid at 1631.
Power escalation continued until July 15, when 93% power was cchieved.
At 1123 on July 16, the reactor automatically shutdown when the Forced Circulation Pumps tripped due to a gaskct failure in the Seal Inject System. Refer to R0 83-07 for a discussion of the event. The reactor remained shutdown for the rest of the month.
Type B leakage tests were conducted on the personnel and emergency airlocks during the month of July. As discussed above, the personnel airlock did not pass the initial test. The as-left leakage rates of the airlocks were as follows:
Personnel Ai rl ock.............. 0.188 SCFH Emergency Ai rl ock.............. 0.389 SCFH l
Significant Instrument and Electrical Department maintenance items performed during the July 1983 reporting period are included on the attached l
Instrument and Electrical Maintenance listing. Significant Mechanical l
Maintenance items performed during the July 1983 reporting period will be j
submitted in a supplement to this report.
