Response to Inspection Report Nos.
50-373/83-01 and 50-374/83-01 Item of Non-Compliance Technical Specification 6.2 requires, in part, that detailed written procedures including applicable checkoff lists shall be prepared, approved and adhered to for the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Appendix A to the referenced Regulatory Guide recommends procedures for filling, venting, draining startup, shutdown, and changing modes of operation of the liquid poison system.
LaSalle Operating Procedure LOP-SC-07, "SBLC System Flushing Procedure," requires that Valve 1C41-F014 be closed and locked after filling the SBLC Test Tank.
Contrary to the above, on January 19, 1983, Valve 1C41-F014 was found unlocked.
The last documented evolution requiring operation of the valve was completion of LOP-SC-07 on January 12, 1983.
Response
t Corrective Action Taken and Results Achieved After the inspector reported this finding on January 19, the Shift Engineer determined that the valve was in the proper position but was not locked.
The Shift Engineer had the valve locked immediately.
Corrective Action Taken to Avoid Further Noncompliance Standby Liquid Control System operating procedures have been reviewed by the operations staff and revisions have been initiated to
[
ensure that locked valves on SBLC are verified returned to proper positions as designated by LAP 240-1, "Use of Locks on Valves".
Procedures which are under revision are LOP-SC-07, "SBLC System Flushing Procedure", LOP-SC-01, " Filling, Venting, and Draining the Standby Liquid Control System (SBLC)" and LOP-SC-M1, "SBLC Pump Flow Test, Inservice Test and Explosive Valve Test".
In addition, mechanical checklists for systems which have locked valves are being revised to provide agreement between mechanical checklist valve positions and the LAP 240-1 Locked Valve Checklist.
Date of Full Compliance Full compliance was achieved on January 19, 1983.
Procedure revision will be completed by May 1, 1983.
