Virginia Electric and Power Company North Anna Power Station, Unit #1
Attachment:
Page 1 of 1 Docket No. 50-338 Report No. LER 79-081/03L-0 Description of Event:
On 6/8/79, IRPI's M-10 and D-10 were both placed in the test mode to allow removal of a jumper previously installed in the Individual Rod Position Indicator System. This event is contrary to T.S. 3.1.3.2.
The IRPI's were calibrated and returned to service within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> as required by Action Statement a.2 of T.S. 3.1.3.2.
This event is reportable as per T.S. 6.9.1.9.b.
Probable Consequences of Occurrence:
Control rod positions and operability of the rod position indicators are required to ensure compliance with the control rod alignment and insertion limits.
Since the IRPI's were operable before and after the removal of the jumper, at no time was the safe operation of the plant affected. As a result, at no time was the health and safety of the public affected.
There are no generic implications.
Cause of the Event:
The IRPI's were removed from service to remove jumpers previously installed as part of an investigation of IRPI drift.
Immediate Corrective Action:
The IRPI's were calibrated and returned to service.
Scheduled Corrective Action:
No further corrective action was required.
Actions Taken To Prevent Recurrence:
