U.S. NUCLEAR REGULATORY COMMISSION.
DETROIT EDISON COMPANY WOLVERINE POWER SUPPLY COOPERATIVE, INC.
DOCKET NO. 50-341 FERMI-2 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating License No. NPF-43, issued to the Det'oit Edison Company (DECO) and the Wolverine Power Supply Cooperative, r
Incorporated (the licensees) for the operation of Fermi-2 located in Monroe County,. Michigan.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
i l
.The proposed amendment would revise the Technical Specifications (TS) for Primary Containment Isolation Valves by removing the Traversing Incore Probe (TIP) Purge System Primary Containment Isolation Valve from the TS.
1 1
The proposed action is in accordance with the licensees' application for l
amendment dated March 10, 1989.
The Need for the Proposed Action:
The proposed changes to the TS are required in order to reflect the elimination of the TIP Purge System Primary Containment Isolation Valves from the plant design.
The purge system is being modified to achieve compliance with General Design Criterion 56 of Appendix A of 10 CFR 50.
Environmental Impacts of the Proposed Action:
The Commission has completed its evaluation of the proposed revision to the TS.
The proposed revision would reflect the elimination of the TIP Purge r9eresD39 g9o g U

\\
System Primary Containment Isolation Valves and the sealing of the associated penetration with a evalified welded cap which will be leak tested per 10 CFR Part 50, Appendix J.
This will reduce the probability of leakage during an accident from this potential leakage path.
In addition, a reduction in occupational radiation exposure can be expected because of lower maintenance, inspection and testing requirements of the new design. Therefore, the proposed changes do not increase the probability or consequences of any accidents, no changes are being made in the types of any effluents that may be released offsite, and there is no significant increase in the allowable individual or cumulative cccupational radiation exposure. Accordingly, the Comission i
concludes that this proposed action would result in no significant radiological impact and could result in the reduction of the radiological impacts.
l With regard to potential nonradiological impacts, the proposed changes to the TS involve systems located within the restricted area as defined in 10 CFR Part 20.
They do not affect nonradiological plant effluents and have no other environmental impact. Therefore, the Comission concludes that there are no significant nonradiological environmental impects associated with the proposed amendment.
The Notice of Consideration of Issuance of Amendment and Opportunity for Hearing in connection with this action was published in the FEDERAL REGISTER on August 1, 1989 (54 FR 31750). No request for hearing or petition for leave to intervene was filed following this notice.
Alternative to the Proposed Action:
Because the Comission has concluded that there is no significant environmental impact associated with the proposed amendment, any alternative would have either no or greater environmental 1mpact.
The principal
g l
.. r alternative would be to deny the requested amendment.
This would prevent the i
design modifications and thus prevent compliance with General Design Criterion 56, i
l' Alternative Use of Resources:
This action involves no use of resources not previously considered in f.
connection with the " Final Environmental Statement Related to Operation of f
Fermi-2," dated August 1981.
g Agencies and Persons Consulted The Commission's staff reviewed the licensees' request and did not consult other agencies or persons, j
FINDING OF NO SIGNIFICANT IMPACT The_ Commission has determined not to prepare an environmental impact state-ment for the proposed license amendment.
Based upon the foregoing environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action, see the application for amendment dated March 10, 1989, which is available for public inspection at the Commission's Public Document Room, 2120 L Street, N.W., Washington, D.C., and at the Monroe County Library System, 3700 South Custer Road, Monroe, Michigan 48161.
Dated at Rockville, Maryland, this 24th of August 1989.
