NUCLEAR REGULATORY COMMISSION a

DETROIT EDISON COMPANY WOLVERINE POWER SUPPLY COOPERATIVE. INC.

DOCKET NO. 50-341 FERMI-2 ENVIRONMENTAL ASSESSMENT AND FINDING 0F NO SIGNIFICANT IMPACT

. The U.S. huclear Regulatory Comission (the Commission);is considering.

issuance c^.an amendment to facility Operating License No. NPF-43, issued to

, the Detroit Edison Company (DECO) and the Wolverine Power Supply Cooperative,

' Incorporated (the. licensees) for the operation of. Fermi-2 located in Monroe County, Michigan.

ENVIRONMENTAL ASSESSMENT Identification ef' Proposed Action:

The proposed amendment.would revise the Technical Specifications (TS) for Isolation Actuation. Instrumentation. The table entries previously listed in a section entitled Containment Isolation" are separated into two sections; one for Primary Containment and one for Secondary Containment' isolation functions.

' Revisions to table entries, table notations and nomenclature are made to either

.more clearly reflect the plant configuration, remove duplication or ambiguity, or reflect the new sections of the table. -Provisions have been included to allow routine testing of the Reactor Water Cleanup system without necessitating

removal of the system from service.

In addition, the definition of Channel Calibration ~is revised to better reflect standard industry practice.

The proposed action is in accordance with the licensees' application for amendment dated December 22, 1988.

2 The Need for the Proposed Action:

The proposed changes to the TS are required in order to provide clearer, more usable TS requirements which more clearly reflect the plant configuration.

Environmental Impacts of the Proposed Action:

The Commission has completed its evaluation of the proposed revision to the TS. The proposed revision would separate the requirements currently grouped together under Table Sections entitled " Containment Isolation" into two sections; one for Primary Containment and one for Secondary Containment isolation functions.. Table entries, table notations and nomenclature are revised.to more clearly reflect the plant configuration, remove duplication or ambiguity or reflect the new table sections. These above changes are proposed to. improve the ability of the plant operators to effectively use the TS and do not modify the intended isolation actuation instrumentation requirements.

New provisions have been proposed to allow routine testing of the Reactor Water Cleanup System (RWCS) without necessitating removal of the RWCS from service provided other means of accomplishing the function under test is provided during the test period. This will reduce the probability of RWCS f ailure and subsequent potential radiological release due to cyclic fatigue from frequent RWCS shutdowns for testing.

In addition, the definition of Channel Calibration is revised solely to better reflect standard industry practice by including specific provisions for channels with Resistance Temperature Detector or Thermocouple sensors. Therefore, the proposed changes do not increase the probability or consequences of any accidents, no changes I

are being made in the types of any effluents that may be released offsite, and 1

there is no significant increase in the allowable individual or cumulative occupational radiation exposure. Accordingly, the Connission concludes that this proposed action would result in no significant radiological impact and could result in the reduction of the radiological impacts.

lw _-

ye With regard to potential nonradiological impacts, the proposed changes to the TS involve systems located within the restricted area as defined in They do not affect nonradiological plant effluents and have 10 CFR Part 20.

no other environmental impact. Therefore, the Commission concludes that there are no significant nonradiologica) environmental impacts associated with the proposed amendrent.

The Notice of Consideration of Issuance of Amendment and Opportunity for Hearing in connection with this action was published'in the FEDERAL REGISTER on June 26, 1989 (54 FR 29118). No request for hearing or petition for leave to intervene was filed following this notice.

Alternative to the Proposed Action:

Because the Commission has concluded that there is no significant environmental impsct associated with the proposed amendment, any alternative would have either_no cr greater environmental impact. The principal alternative would be to deny the requested amendment. This would not provide the safety benefits of clearer, more usable T5 requirements or eliminate the potential cyclic fatigue of frequent RWCS shutdowns for testing..

Alternative Use of Resources:

This action involves no use of resources not previously considered in connection with the " Final Environmental Statement Related to Operation of Fermi-2," dated AJgust 1981.

Agencies and Persons Consulted The Commission's staff reviewed the licensees' request and did not consult other agencies or persons.

FINDING OF NO SIGNIFICANT IMPACT The Commission has determined not to prepare an environmental impact state-ment for the proposed license amendment.

, i*

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.
