50-328 SEQUOYAH NUCLEAR PLANT - FIRE FROTECTION IMPROVEMEN1 P1AN A working meeting between TVA and NRC was held on August 19, 1991, at Sequoyah to discuss the problems TVA had identified relstive to Sequoyah's fire protection program. As TVA committed during this meeting, Enclosure 1 provides the fire protection improvement plan desigaed to effect complete program recovery. contains the commitments speciried in the improvement plant these commitments supersede previously submitted individual commitments.. Quarterly status reports will also be submitted as committed in the working meeting.
If you have any questions concerning this submittal, please telephone M. A. Cooper at (615) 843-8422.

1%Cl.0 SURF: 1 SS1 910930 801 FIRE PROTECTION IMPROVEMENT PLAN SEQUOYAH NUCLEAR PLANT This plan contains the major work activities required to correct utility identificd weaknosses in the firo protection program at Sequoyah Nuclear Plant (5 011).
The plan is divided up into four phason with targoted completio.: datos.
Although exact duration of soma activitics can only be estimated at this timo due to undefined scope it is anticipated the activition can be finalized within the timo framo of their ar kned phase.
'It in the mission of thin improvement plan and the desires of TVA Management to ensure that all weaknesson in tho SON firo protection program be adequatoly identified and corrected.
The phase dates are intended to supersede any previously mado schedules in that all commitments and identified weaknesses will now be prioritized and impicmo' tod by the Firo protection Improvement Plan Task Forco.
Status reports on 7mprovement plan progress will be provided per Attachment A.
