-SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION-RELATED TO AMENDMENT NO. 96 TO FACILITY OPERATING LICENSE NO. DPR-6 CONSUMERS POWER COMPANY BIG ROCK POINT PLANT

)

DOCKET NO. 50-155

1.0 INTRODUCTION

By letter dated December 19, 1988, Consumers Power Company (the licensee) requested amendment to the Big Rock Point Plant Facility Operating License- 1 (FOL)No.DPR-6. The proposed amendment would allow for an increase in the amount of by-product material the plant may possess and use from 10.5 curies l

of Cesium-137 to 45 curies of Cesium-137 as sealed sources.

2.0 EVALUATION The licensee proposes to use a new calibration source of greater strength which could provide the capability to functionally check and calibrate por.able radiation detection instruments on all ranges with greater accuracy. The new sealed calibration source and the associated housing would be J. L. Shepherd Model 89 design. This sealed source has been registered (CA598D108U) by the California Department of Health Services for Cesium-137 with a maximum activity of 440 curies. Big Rock Point preposes to change their FOL by increasing the by-product material it may possess from 10.5 curies of Cesium-137 to 45 curies of Cesium-137 which is within the registered maximum activity for this sealed source.

The licensee will be leak testing the calibrator semiannually, in accordance with Technical Specification Section 10, Subsection 6.16, to detect the presence of 0.005 microcuries or more of removable contamination.. The use of the calibrator will be procedurally controlled and operated by only qualified personnel.

The Technical Specification requirements for the sealed source are unchanged 'i and, therefore, the change in the FOL to increase the sealed source limit to 45 curies of Cesium-137 by-product material is acceptable.  ;

3.0 ENVIRONMENTAL CONSIDERATION

This amendment involves a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and a change in a surveillance requirement. We have determined that the amendnent involves no significant increase in the amounts, and no significant change in the types,.of any effluents that may be released offsite, and that there is no significant increase in individual 3r cumulative. occupational radiatio'n exposure. The Commission has previou' sly issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement .

or environmental assessment need be prepared in connection with the issuance

' of this amendment.

4.0 CONCLUSION

We have concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
