7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION GENERAL PUBLIC UTILITIES NUCLEAR CORPORATION THREE MILE ISLAND NUCLEAR STATION. UNIT 2 DOCKET NO. 50-320 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an exemption to License No. DPR-73, issued to GPU Nuclear Corporation (GPUN or the licensee), for the Three Mile Island Nuclear Plant, Unit 2 (THI-2) located in Londenderry Township, Dauphin County, Pennsylvania, on an island in the Susquehanna River. The licensee holds a Possession Only License that allows GPUN to possess but not operate THI-2.
ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action:
The NRC, on its own motion, is considering granting an exemption from the training program establishment, implementation, and maintenance requirements of 10 CFR 50.120. The licensee, in its letter of July 29, 1993, provided supplemental information supporting this action.
The Need for the Proposed Action:
The TMI-2 is currently in the final stages of readying the facility for long term storage, termed Post Defueling Monitored Storage. The licensee has completed a multi-year fuel removal and decontamination program that began I
just after the March 28, 1979 accident. The reactor fuel has been shipped offsite and the facility is currently in a safe stable condition conducive to long term storage. There is no longer any requirement to have licensed operators at the facility and the Technical Specifications _for TMI-2 do not 9312010121 931117 PDR.ADOCK 05000320 P
. require manning the control room. On September 14, 1993, GPUN was granted a Possession Only License which prohibits operation. The proposed exemption would relieve the licensee from the requirements of 10 CFR 50.120. However, it would not relieve the licensee from previous requirements or commitments to train and qualify facility personnel.
Environmental Impacts of the Proposed Action:
The proposed action does not have any effect on accident risk and the possibility or environmental impact is extremely remote. The THI-2 reactor vessel has been defueled and the fuel shipped offsite.
Remaining residual fuel is of insufficient quantity and configuration to result in an inadvertent criticality. Many of the functional programs (i.e. training, site security, emergency preparedness and radcon) that were once required as facility specific to THI-2 have been assumed by the Three Mile Island Nuclear Station, Unit 1 (TMI-1) organization. TMI-1 is required to comply with 10 CFR 50.120.
The existing training programs for the few remaining TM1-2 personnel are deemed acceptable, given the low level of activity at the facility and the shutdown and defueled status of the plant.
Based on the staff review of the July 29, 1993 submittal, the staff concludes that the environmental and safety consequences of &ccidents which may potentially result in a radiological release are greatly decreased given the permanently shutdown and defueled status THI-2.
Therefore, the proposed action does not increase the probability or consequences of any accidents, no changes are being made in the types of any j
effluents that may be released offsite, and there is no significant increase j
in the allowable individual or cumulative occupational radiation exposure onsite.
J
.. Accordingly, the NRC staff concludes that the proposed action would result in no significant radiological environment impact. With regard to potential nonradiological impacts, the proposed action does not affect nonradiological plant effluents and has no other environmental impact.
Therefore, the NRC staff concludes that there are no significant nonradiological environmental impacts associated with the proposed action.
Alternative to the Proposed Action:
Since the Commission concluded that there are no significant environmental effects that would result from the proposed action, any alternative with equal or greater environmental impacts need not be evaluated.
The principal alternative would be to deny the action. This would not reduce environmental impacts of plant activities and would not enhance the protection of the environment nor public health and safety.
Alternative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Programmatic Environmental Statement for THI-2, dated March 1981, as supplemented.
Aaencies and Persons Consulted:
The NRC staff consulted with representatives of the State of Pennsylvania regarding the environmental impact of the proposed action.
FINDING 0F NO SIGNIFICANT IMPACT:
Based upon the foregoing environmental assessment, the NRC staff concludes that-the proposed action will not have a significant effect on the quality of the human environment.
Accordingly, the NRC staff has determined, pursuant to 10 CFR 51.31, not to prepare an environmental impact statement for the proposed action.
For further details with respect to this action, see the licensee letter dated July 29, 1993, which is available for public inspection at the Commission Public Document Room, the Gelman Building, 2120 L Street, i
NW., Washington, DC 20555, and at the local public document room for TMI-2 at the Government Publications Section, State Library of Pennsylvania, Walnut Street and Commonwealth Avenue, Box 1601 Harrisburg, Pennsylvania 17105.
Dated at Rockville, Maryland, this 10th day of Novtober 1993.
