NUCLEAR REGULATORY COMMISSION t WASHINGTON, D.C. 2066H001 e o SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.151 TO POSSESSION ONLY LICENSE NO. DPR-3 l

YANKEE ATOMIC ELECTRIC COMPANY YANKEE NUCLEAR POWER STATION (ROWE)

DOCKET NO.50-029 l

1.0 INTRODUCTION

By letter dated October 15,1998, the Yankee Atomic Electric Company (YAEC or licensee) proposed to amend the Possession Only License No. DPR-3 for the Yankee Nuclear Power Station (YNPS or plant) by changing the submittal interval for the Radioactive Effluent Reports from semiannual to annual.

2.0 BACKGROUND

The reactor was first made critical in 1960, began commercial operation in 1961, and operated until permanent shutdown on October 1,1991. The nuclear steam supply system was a four- l loop pressurized-water reactor designed by the Westinghouse Electric Corporation. A l Possession Only License was issued on August 5,1992. On December 20,1993, YAEC l submitted a Decommissioning Plan (Plan) and requested NRC approval of the Plan. In an NRC Order dated February 14,1995, and subsequently by letter dated October 28,1996, the Plan was approved. The Plan permitted YAEC to decontaminate and dismantle the structures and components at the site. Decommissioning activities have been proceeding under the approved Plan. As of late in 1998, most systems not required to support the storage of spent fuel have been dismantled and removed. The Spent Fuel Pool and other support systems associated with fuel storage have been electrically and mechanically isolated from all other  ;

remaining plant systems so that spent fuel will not be adversely impacted by future site activities.

3.0 EVALUATION As revised in 1992,10 CFR 50.36a, " Technical specifications on effluents from nuclear power reactors," in section (a)(2) states in part, "Each licensee shall submit a report to the Commission annually that specifies the quantity of each of the principal radionuclides released to unrestricted areas in liquid and in gaseous effluents during the previous 12 months, including any other information as may be required by the Commission to estimate maximum potential l annual radiation doses to the public resulting from effluent releases . .," Prior to its submission of this license amendment application, YAEC had been voluntarily submitting these reports semiannually, based on an earlier version of this regulation. Based on the requirements of the current regulation, as quoted above, the staff concludes that annual submission of the Effluent Release Report is appropriate and, therefore, acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Commonwealth of Massachusetts state liaison official was notified of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment makes an administrative change to the TS, related to recordkeeping, reporting,'or administrative procedures or requirements, and has no effect on requirements with respect to instaihtion or use of facility components located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment 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 or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (63 FR 64128). Accordingly, 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 or environmental assessment need be prepared in

- connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there ,

is reasonable assurance that the health and ,afety of the public will not be endangered by j operation in the proposed manner, (2) such activities will be conducted in compliance with the l Commission's regulations, and (3) the issuance of the amendment will not be inimical to the l common defense and security or to the health and safety of the public.
