SUBJECT:

FORT ST. VRAIN SCHEDULE C0HilTMENT ITEMS - REVISION 6 (TAC NO. 54373)

Reference:

1.PSCletterdatedJanuary4,10P8(P-88012);Proposedschedule rniston for the concitnent items associated with the CRDOA EACK-EMF testing program.

?. PSC letter dated January 15,19PP (P "0MO); Submittal of cur rent construction status for Aprv.Jix R rnodifications.

3. PSC letter dated January 18, 19PP (P-88031); Perforr.ance er.hancerent progran update.

4. NPC letter dated Septen.ber 29, 1987; Implementation schedule fer 10 CFR 50.48 and Apperdix R fire protection acdifications-Fort St. Vrain Nuclear Generating Station.

The staff has reviewed your submittals, F.eferences 1 thru 3. concerning changes you have requested to corrritr,ents for the Fort St. Vrain Nuslear Generating Station (FSV). We have individually exar.iined each char.ge and our discussion follows:

Irproved Control Roc Drive Mechanism CPDM Surveillarce Procram - You ha ve pWe's'eY W FeTeFehiE Tt'o'TuFth,e(F 'ei)tFnTths'tTmE'tF 'pFo'vTde improved CRCM surveillar.ce program.

The prir.ary cause for the further delay is the FSV's limited operating tire at higher reactor power levels.

The staff agrees that a lack of operating data at higher power levels is e valid reason for delay.

In your letter (Reference 1) you proposed an extended schedule, with the improved CRCP surveillance program being submitted approximately 150 days after the startup of the fourth refueling outage or approximately July 1989.

The staff finds this proposal acceptable.

Please note that the staff's intention is to review your revised CPCM surveillance program. Supporting 8903040266 800226 PDR ADOCK 05000267 P

R. O. Williams material such as the proposed testing nethods and parameters may be sutinitted for coment.

However, the staff's preference would be to review the entire program after it is developed.

Appendix R Modifications - Emergeney Ligh_ ting, System - In your letter, _

c Reference 2, you requested ~aWitional time to coEplete the installation of the emergency lighting system.

This additional delay of approximately 6 weeks is to allow for replacenent of storage batteries damaged due to inadequate storage conditions.

The staff finds this delay is acceptable.

Perfomance Enhancement Program (PEP) Review - In your letter, Reference T~yFu request th~a't'~the~ interval for the neetings on the PEP be extended to one year. The staff notes that the significant improvements in your perforrance, both during plant operation and outages, are evident. This improvenent is docunented in the reports of the Systematic Assessment of Licensee Performance (SALP).- Therefore, the staff concurs that the PEP program review should occur once per year.

The staff's preference is to combine this neeting with your response to the annual SALP report.

A revised sumary of your ccernittents is enclosed.

Sincerely,

\\1 Kenneth L. Heitner, Pro.iect Manager Project ~ Directorate - IV Division of Reactor Project - III, IV, Y and Special Projects Office of Nuclear Reactor Regulation

4 R. O. Williams material such as the proposed testing methods and parameters may be submitted for connent. However, the staff's preference would be to review the entire program af ter it is developed.

PCRV Tendon Surveillance Program - In your letter Reference 2. you note that in an earlier submittal dated July 20. 1987 (P-87234) an alternative PCRV Tendon Surveillance Program was proposed. The key features of this alternative program are that the surveillance intervals are extended from 6 to 12 months. The cycle for new tendons selected for liftoff testing is extended from 18 to 24 months.

In considering this extension. the staff notes that over 80% of the tendons have been examined. so the data sample is f airly complete.

Repeated testing of the control group tendons by liftoff shows no obvious degradation over three years. The five worst case tendons are stable, and still acceptable by the end of life criteria in the FSAR.

Based on the above considerations. the staff finds your revised PCRV tendon surveil-

-lance program is acceptable.

Appendix R Hodifications - Emergency Lightino System - In your letter.

Reference 3. you requested additional time to complete the installation of the emergency lighting system. This additional delay of approximately 6 weeks is to allow for replacement of storage batteries damaged due to inadequate storage conditions. The staff tinds this delay is acceptable.

Performance Enhancenent Program (PEP) Review - In your letter. Reference

4. you request that the interval for the meetings on the PEP be extended to one year. The statt notes that the significant improvements in your performance, both during plant operation and outages. are evident. This improvement is documented in the reports of the Systematic Assessment of Licensee Performance (SALP). Therefore, the staff concurs that the PEP program review should cccur once per year. The staff's preference is to combine this meeting hith your response to the annual SALP report.

A revised sumary of your commitments is enclosed.

Sincerely.
