IAEA Re ortable Occurrence 86-02 Summar of Event:
Temporary Procedure (TP) 260 was initiated on Friday, 3une 6, to verify the cranking diesel load capability.
The cranking diesel provides its load to the plant through the 0C OKV bus, but only when the bus is de-energized.
To perform TP 260, the OC OKV bus was de-energized to simulate a loss of off-site power.
At the conclusion of the test, the OC OKV bus was de-energized from the cranking diesel and re-energized by its normal power supply.
On 3une 6, 1986, during the transition from normal power to cranking diesel power through the OC OKV bus, the lights in the spent fuel pool went out for 20 minutes.
This was reported to the IAEA in Occurence 86-01.
Prior to returning the system to normal, the plant back-fit organization requested that the system be left in the off-normal condition so that required modifications could be implemented.
This resulted in the transition back to normal power occurring on 3une 12, 1986, with the resultant de-energization of the Spent Fuel Pool lighting and bridge cane.
Although this interruption in the IAEA monitoring program was a consequence of performing TP 260, it occurred greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> af ter the first interruption and requires this additional report.
Results:
1)
The lighting in the spent fuel pool was off from approximately 0200 to 0230 on 3une 12, 1986.
2)
The spent fuel bridge crane was incapable of movement during the time the lights were out because it was de-energized from the same bus which de-energized the lighting.
==
Conclusion:==
There were no fuel inventory changes during the time when the camera surveillance was interrupted during the performance of TP 260.
