50-328 SEQUOYAll NUCLEAR PLANT (SQN) - FIRE PROTECTION IMPROVEMENT PLAN PERIODIC STATUS REPORT A working meeting between WA and NRC was held at SQN on August 19, 1991, to discuss the self-identified problems in SQN's fire protection program and the improvement plan efforts initiated by TVA. As a result of this meeting, WA agreed to submit periodic status reports to inform NRC on the progress of efforts made in conjunction with the improvement plan.
The most recent status report identifying progress achieved and areas needing further action is included as Enclosure 1.
Changes to the improvement plan are identified in Enclosure 2.
The scheduled completion date for Phase III is October 1, 1993, with the majority of the items expected to be finished near the end of the period. The status reporting period af ter this report will be changed to semiannual in conjunction with the currently scheduled completion dates.
If you have any questions concerning this submittal, please telephone M. A. Cooper at (615) 843-8924.
