Virginia. Electric and Power _ Company North Anna Power Station, Unit No. l' Attachment: Page 1 of 2 Docket.No.-50-338 Report No. LER 83-021/03L-0
Description of Event
On April 11, 1983, with Unit 1 in Mode 1, a Maintenance Report was issued on Fire Door S-71-7, between the Service Building Health Physics Area and the Auxiliary Building, because the door would not consistently self close.
.However, at the time, the fire door was considered operable. About three hours later, one of the fire protection personnel discovered the reclosure device on Fire Door S-71-7 had been removed without a fire watch being posted.
(With the.reclosure device ' removed the fire door would not self close). The Shift Supervisor was~promptly notified and a Fire Watch was subsequently posted.
This event is reportable pursuant to T.S. 6.9.1.9.b.
Probable Consequences of Occurrence A fire watch was posted within one hour af ter the fire door was found inoperable.-
Consequently, the public health and safety were not affected.
Cause of Event
The Fire Door in question would not self close because the reclosure mechanism had been removed for repairs on the reclosure coupling (pullback from.the frame to door). The coupling was misaligned and loose and causing increasing problems with door operability.
The reclosure device was removed for maintenance without notifying the Shif t Supervisor. As a result, no fire ~ watch was stationed at the door until the Shift Supervisor was notified of the situation by fire protection personnel.
Immediate Corrective Action
The coupling on the reclosure mechanism was repaired, the device reinstalled and adj usted.
Proper door operation was subsequently verified.
~
Scheduled Corrective Action No corrective action is scheduled.
Attachment:
Page 2 of 2 Actions Taken to Prevent Recurrence The Shift Supervisor involved was informed that the operability of Fire Door S-71-7 was required as per Technical Specification 3.7.15.
The Tech Spec designation was not noted on the original maintenance report written earlier in the day.
Personnel who removed the reclosure device for maintenance without notifying the Shift Supervisor have been cautioned by one of their supervisors that a fire watch is required for an inoperable fire door as required in Technical Specifications.
Generic Implications There are no generic implications to this event.
