1. INTRODUCTION

. Fort St. Vrain (FSV) is a high-temperature, gas-cooled reactor owned and operated by Public' Service Company (PSC) of Colorado. FSV is located approximately 35 miles north of Denver and 5.6 km (3.5 miles) northwest of the town of Platteville in Weld County, Colorado. FSV had a capacity of 330 HWe. The PSC-owned site consists of approximately 11,320 me (2798 acres).

FSV was shutdown on August 18, 1989, because'of control-rod drive failures. The shutdown was made permanent because of a subsequent discovery of degradation of steam generator ring headers. About one-third of the spent fuel was initially removed from the core (the maximum capacity of the spent fuel storage wells). 1 PSC completed the construction of an independent spent fuel storage installation i (ISFSI) in August 1991 and received U.S. Nuclear Regulatory Commission approval (10 CFR Part 72 license) to store spent fuel in November 1991. PSC has trans-ferred all 247 elements of FSV fuel to the ISFSI.

The staff issued, on November 23, 1992, an Order Approving the Decommissioning Plan (PD) and Authorizing Decommissioning. The licensee _ selected the dismantlement / decontamination option as the decommissioning alternative, and l decommissioning is complete. PSC estimates that the FSV license will be terminated in 1997, and FSV released for unrestricted use.

The major dismantlement and decontamination activities performed during decommissioning were divided into three primary work areas: (1) decontamination and dismantlement of the prestressed concrete reactor vessel (PCRV); (2) decontamination and dismantlement of the contaminated balance-of-plant (B0P) systems; and (3) final site radiation survey. To support the FSV decommissioning activities, NRC conducted 24 inspections at FSV. The most recent inspections (inspections conducted from February 1996 through October 1996) focused on supporting the final radiation survey review, i

' The licensee conducted termination surveys to assess residual radioactive '

contamination levels at the facility. The termination surveys were conducted in a phased approach. The licensee completed 7.e final radiological survey in

! October 1996. The final survey report documented the level of residual i radioactivity remaining at the facility and affirmed that the residual

. radioactivity met unrestricted use criteria established by the NRC, and that the site was suitable for release for unrestricted use.

2. EVALUATION The proposed changes to the FSV Possession-Only License No. DPR-34 is administrative in nature and redesignates the approved DP, the approved

" Supplement to Applicant's Environmental Report - Post-0perating License Stage -

Decommissioning" and the approved Final Radiation Survey Plan as the License Termination Plan.

In summary, because of the procedural nature of the change, the amendment request does not create a new or different accident than previously analyzed in the DP.

All the accident scenarios previously analyzed in either the decommissioning technical specifications or the DP, and the offsite doses resulting from these accidents, were insignificant. The staff is approving the amendment based on the procedural nature of the changes and because the previously analyzed accidents in the DP were not changed.

3. ENVIRONMENTAL CONSIDERATIONS The amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10). Pursuant to 10 CFR 51.22(b), no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of this amendment.

4. AGENCIES AND PERSONS CONSULTED In accordance with the Commission's regulations, the Director of Radiation l Control, Colorado Department of Public Health and Environment was notified of the proposed issuance of the amendment. The State had no comments on the proposed I amendment.

! 5. CONCLUSIONS The Commission has concluded, bas'.d on the considerations above, that:

(1) because the license amendment Joes not involve an increase in the probability nor consequences of accidents previously evaluated, nor create the possibility of a new or different kind of accident from any accident previously evaluated, and does not result in a reduction in a margin of safety, the amendment does not involve a significant hazard consideration; (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; (3) such activities will be conducted in cotopliance with the

Commission's regulations; and (4) the issuance of the amendment will not be .
