NRC INSPECTION REPORT 50 317/90-08 AND 50 31W90-08 i
STATEMENT OF VIOLATION Calvert Cliffs Technical Specification 6.8.1 states that written procedures shall be established, maintained, and implemented covering the applicable procedures recommended in Appendix *A* of Regulatory Guide 1.33, Revision 2, February 1978. Appendix "A* of Regulatory Guide 1.33. Rev. 2, 1978, requires administrative procedures for equipment control (e.g., locking and tagging).
Administrative procedure Calvert Cliffs Instruction (CCI).309B requires that the operation of any locked valve be annotated and approved in the '1.ocked Valve Deviation Log".
+
Contrary to the above, on April 20,1990, three valves were unlocked and repositioned in the Waste Gas Decay system without adequate documentation and verification which resulted in an unplanned release of the #13 Waste Gas Decay Tank.
IIACKGROUND
An unplanned release of #13 WGDT occurred during the recent startup of Unit One. The event was reviewed by our Startup Review Board which consisted of all site Managers. Evidence of insufficient attention to detail and informality of communications was revealed. This has received management attention and additional emphasis through communications and monitoring will be presided.
A Human Performance Evaluation System review was performed and identified the lack of clarity regarding the intent of CCI.309B, " Locked Valves," as contributing to the event. The following specific problems were noted in CCI 3098:
CCI 309B states that, "Whenever any locked valve is taken out of ".s locked position, such deviation shall be logged in the Locked Valve Deviation Log " However, CCI 3098 does not specify that the valve be logged before it is taken out of its locked position. In this event, the log was completed after the valve was taken out of its locked position.
CCI 309B requires that the Control Room Supervisor (CRS) approve a locked valve deviation before the valve is placed in the out of normal position, but does not specify how the approval must be given. A space is provided in the log for his initials approving the deviation, but since the log is not required before the valve manipulatinn, ti., procedure implies that he can give his approval by other methods. In this case, C'AS permission was given to manipulate the valves prior to their being logged by directing the WGDT release to be performed.
The event and all corrective actions are discussed in LER $0 317S016.
col (RECTIVE STEPS TilAT llAVE BEEN TAKEN The intent of CCI 309B regarding control of locked valves was formally communicated in writing to the operating shifts. A valve deviation sheet will be completed prior to operating locked valves and the Control Room Supenisor will document his approval of those operations by initialing the sheet.
CORRECTIVE STEPS TilAT WILL BE TAKEN TO AVOID FURTIIER VIOLATIONS A revision to CCI.309 to clarify the required documentation and verification of the operation of locked valves has been recommended foi approval by the Plant Operations and Safety Review Committee and is expected to be implemented by July 31,1990-1
