NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20666-0001

. . . . . ,o SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING THE ORDER TERMINATING FACILITY LICENSE NO. R-81 CINTICHEM. INC. RESEARCH REACTOR DOCKET NO. 50-54

1.0 INTRODUCTION

By application dated October 19,1990, as supplemented January 11,14,28, February 19, March 8, April 24, May 21, June 25, July 17, August 6, and October 2,1991, the licensee requested authorization to dismantle the 5 Megawatt Research Reactor, dispose of the component parts in accordance with the proposed decommissioning plan, and terminate Facility License No. R-81. An " Order Authorizing Dismantling of Facility and Disposition of Component Parts," dated November 21,1991, was published in the Federal Reaister on November 27,1991, (56 FR 60124). In addition, the staff of the Nuclear Regulatory Commission (NRC) required Cintichem to develop residual soil contamination criteria for use as unrestricted release criteria for the facility. These were submitted on October 22,1992, and approved on August 26,1993. On February 1,1994, Cintichem requested approval of residual contamination criteria for five additional radionuclides that were not included in the original submittal. The staff approved the criteris for the five additional radionuclides on October 17,1994. Unrestricted release criteria for surfaces were those described in NRC Regulatory Guide 1.86. These criteria were modified in October 1994 to increase the limits for tritium (H 3) and iron-55 (Fe-55) in accordance with NRC guidance. Cintichem was also required to demonstrate that the dose to a critical member of the public from all residual radioactive material on site did not exceed 10 millirem per year. In addition, the dose via the water pathway alone could not exceed 4 millirem per year.

2.0 EVALUATION Due to the large geographical size of the site and the considerable number of radiation survey data points recorded, the final radiation surveys were divided into five sequential phases. For each phase, Cintichem conducted radiation surveys using techniques recommended in NUREG/CR-5849, " Manual for Conducting Radiological Surveys in Support of License Termination", to show that unconditional release criteria were satisfiad. The i licensee completed the dismantlement and submitted final survey reports and addenda for

! the five phases dated January 26,1995, March 3,1995, March 26, April 19 and June 7, 1996, June 6 and 27,1997, July 3 and 30,1997, and September 22,1997.

Representatives of the Oak Ridge institute for Science and Education (ORISE), under contract to NRC, conducted five surveys of the Cintichem facility during the period April 1995 inrough August 1997. The surveys are documented in the following ORISE reports.

1. Confirmation Survey of the Exterior Areas of Buildings 1 and 2, May 1995
2. Confirmation Survey of the Phase 2 Areas of the Reactor Building, September 1996
3. Confirmation Survey of the Unaffected Land Areas, September 1996
4. Confirmation Survey of the Phase 4 Areas, May 1997
5. Confirmation Survey of the Phase 5 Areas, April 1998  ;

In addition, an Addendurn to the Phase 5 Confirmatory Survey Report, " Bedrock Dose Assessment Report," was submitted to the NRC on June 2,1998.

The staff finds that the ORISE reports support the data developed in the licensee's final survey report, and that all measurements indicate the remaining facilities are suitable for unconditional release.

On May 27,1998, Cintichem affirmed that all radioactive material stored on site had been removed from the facility. This was confirmed by inspection of the site by NRC and the State of New York on June 15,1998.

The results of Cintichem's surveys and the ORISE confirmatory surveys demonstrate that the facility meets the criteria for unrestricted use prescribed in the approved decommissioning plan as supplemented. The staff finds that since these criteria have been met there is no significant impact on the environment and the facility can be released for unrestricted use.

3.0 ENVIRONMENTAL CONSIDERATION

The Commission has prepared an Environmental Assessment (EA), which was published in the FEDERAL REGISTER on August 19,1998 (63 FR 44476). On the basis of the EA and the above Safety Evaluation, the Commission has determined that no environmentalimpact statement is required and that issuance of this Order terminating the license will have no significant adverse effect on the quality of the human environment.

4.0 CONCLUSION

Based on the foregoing considerations, the staff concludes that Facility License No R-81 can be terminated without undue risk to the health and safety of the public or workers, and without any significant impact on the public or environment.
