Senior Vice President, Nuclear Operations Public Service Company of Colorado Post Office Box 840 Denver, Colorado 80201-0840

SUBJECT:

RESOLUTION OF PROPOSALS TO CHANGE COMMITMENTS CONCERNIllG FORT ST. VRAIN (TAC NO 72063)

This letter is in response to your letter dated January 20, 1989, concerning proposed and planned changes to comitments made by Public Service Company of Colorado (PSC) with regard to the Fort St. Vrain f cclear Generatin9 Station (FSV). The staff has reviewed your proposals and provided comments in the enclosure to this letter which correspond to your proposals. However, this letter does not at this time provide specific relief from your comitments which have been confirmed by Order. Relief from those commitments must be formally requested in a separate letter which specifically refers to the Order involved. '

In order to have a firm basis for granting relief from your comitments, it is the staff's view that your comitment to terminate FSV operations on or before June 30, 1990, must be included in the current license. Therefore, the staff requests that you submit an amendment to facility Operating License No. DPR-34 specifically amending Section 2.0 of the license to include:

(4) Early Shutdown The licensee is not authorized to operate the reactor (above 5 percent of full power) for electric power production after June 30, 1990.

The staff will grant relief after the revised license amendment is issued. The staff may also confirm specific ether comitments that the staff believes are important to safety at FSV, even with power operations eliminated.

. Enclosure DETA! LED COMMENTS-ON CHANGES TO COMMITMENTS.BY PUBLIC. SERVICE COMPANY OF COLORADO NRC CONFIRMATORY ORDER AND OTHER VRITTEN COMMITMENTS I.A. Fire Protection Modifications The staff will accept PSC's recommendations as submitted. PSC should provide a written comitment to the proposed schedule. It is the staff's intention to i confirm by Order selected items, including the completion of Emergency Lighting and Fire Detection.

I.B. Upgrade Emergency Operating Procedures The staff will accept PSC's recommendations as submitted. PSC should provide a written request to modify the August 2,1985 Confirmatory Order to indicate that the upgraded E0P's will be implemented by September 30, 1989. TAC No.

44504 is closed.

I.C. Submit Annual Reports on the Control of Moisture Ingress The staff will accept PSC's recommendations as submitted. PSC should provide a written request to modify the September 15, 1988 listing of comitments to reflect this change.

I.D. Evaluate Control of Moisture in CRDM Purge System The staff will accept DSC's recommendations as submitted. PSC should provice a written request to mod.fy the September 15, 1988 listing of comitments to reflect this change.

I.E. Technical Specification Upgrade Program The staff will accept PSC's recommendations as submitted. PSC should provide a written request to modify the September 15, 1988 listing of comitments to reflect this change. However, the staff notes that at the proposed time for submittal, all technical issues related to defueling may not be resolved. In that case, the staff notes that supplementary submittals may be required.

I.F. PCRV Tendon Surveillance Pending acceptable results from the current (1989) surveillance program, the staff will accept PSC's recommendations as submitted. FSC should provide a written request to modify the September 15, 1988 listing of comitments to reflect this change.

t '. j I.G. Regulatory Guide 1.97 Post Accident Monitoring The staff will accept PSC's recommendation of no further upgrades except as allowed without a plant outage. PSC must provice the staff a complete status report of all the RG 1.97 instrumentation, clearly indicating its current

! status. PSC should request that the August 2,1985 Confirmatory Order be modified to read: " Complete as per the status report submitted on ....".

II.A. Safety Parameter Display System l

The scaff will accept PSC's recommendations as submitted. PSC should provide a written request to modify the August 2,1985 Confirmatory Order to indicate that the SPDS will not be implemented. All currently operable computer systems used by the operators should be maintained for the balance of plant life'~ I II.B ACM Backfeed Enhancements The staff will accept PSC's recommendations as submitted. PSC should provide a written request to modify the September 15, 1988 listing of comitments to reflect this change. However, the staff will reconsider the vulnerabilities of the plant to sta 1on blackout during the defueling period and may consider retention of the ACM in that evaluation.

II.C. Control Rod Drive Orifice and Assembly The staff will accept PSC's recommendations as submitted. PSC should provide a written request to modify the September 15, 1988 listing of comitments to reflect this change.

II.D. Fuel Surveillance Program The staff notes that certain aspects of the fuel surveillance program potentially could support the licensing of an Independent Spent fuel Storage Installation (ISFSI). (The Surry ISFSI had certain limits placed on the condition of the fuel that the ISFSI could accept.) The staff is still evaluating the proposal to cancel this program and may issue further correspondence on this topic.

NRC TECHNICAL ASSIGNMENT CONTROL LIST COMMITMENTS 1.A. Safeguards - Miscellaneous Amendments PSC's comitment is acceptable.

I.B. Fire Protection Program Plan Approval & Deletion of Fire Protection Technical Specifications PSC's comitment is acceptable.

I.C. EQ Temperature Profiles PSC's comitment is acceptable.

s II.A. Operator Requalification Program PSC must continue to meet the requirements for licensed operators as per 10 CFR Part 55 and the Technical Specifications until all fuel is removed frcm the reactcr. A conference call was held on March 3, 1989 with the PSC staff (M. Holmes and T. Borst) to discuss this issue.

II.B. Control Room Habitability PSC should clarify the status of continued use of chlorine gas at the site fol-lowing the shutdown of the reactor. If chlorine gas use is continued, it is the staff's position that the proposed May 31, 1989 submittal could be considered an interim neeasure. The staff intends to reevaluate the need for PSC to fully comply with the requirements of GL 83-36 and 83-37 concerning control room habitability.

II.C. 10CFR50.62OperatingReactorReviews(ATWS)

The staff accepts PSC's proposals. However, PSC should complete all actions for which it has made previous written commitments, including its responses to GL 83-28.

II.D. Station Blackout Analysis The staff 6CCEpts PSC's proposals. However, PSC should not take any action for final disablement or removal of the ACM system until this is finalized in the shutdown Technical Specifications.

III.A. Control Room Design Review (CRDR) Modifications ,

The staff accepts PSC's proposals. Hcwever, PSC should prepare and retain en site documentation sumarizing the changes made and the items identified as Human Engineering Deficiencies, but left unresolved. Improvements made to the control roum should be maintained for the balance of plant life. TAC No. 56125 is closed.

III.B. Control Rod Drive Orifice and Assembly (CRD0A)

The staff accepts PSC's proposals. TAC Nos. 61601 and 62198 are closed.

III.C. Indivioual Plant Examination for Severe Accident Vulnerabilities The staff accepts PSC's proposals.

I. III.F. Inservice Inspection and Testing Program The staff notes that PSC has stated it will continue to use specific facilities that were to be addressed by future upgrades to the Technical Specifications as

.part of the ongoing ISIT efforts. Specific areas to be addressed included:

- Fuel Storage Facility Surveillance

- Category III Systems - Fuel Storage Facility Auxiliary System, and

- Category IV Systents - Fuel Storage Well HVAC.

Other systems noted in the staff's safety evaluation for Amendment No. 51 dated March 9, 1987 which PSC intends to utilize following the final reactor shutdown and cooldown should also be addressed by the ISIT prograni.

Additionally, the fuel handling machine will see exter.sive service during the proposed defueling operation. The fuel handling machine is a Class I system as per the FSAR and should be covered by an appropriate ISIT program. PSC should

. rapidly develop and submit for staff review an ISIT program to cover these sys-tems. This could be either as part of the Technical Specifications or as a separate, but NRC approved program plan. PSC's response to this letter should contain a specific schedule and commitnent to an appropriate ISIT program upgrade. The balance of PSC's proposal is acceptable.

III.G . Seismic Qualification Utility Group (SQUG) Walkdown The staff accepts PSC's proposals. TAC No. 69448 is closed.
