7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION INDIANA AND MICHIGAN POWER COMPANY DOCKET NO. 50-316 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 DPR-74, issued to Indiana and Michigan Power Company (the licensee),
for the Donald C.
Cook Nuclear Plant, Unit 2, located in Berrien County, Michigan.
ENVIRONMENTAL ASSESSMENT Identification of pro osed Action:
The amendment would revise the provisions
'in the Technical Specifications to extend 18-month surveillances from December 31 1987 to the refueling outage currently scheduled to begin in early 1988 for response-time testing for reactor trip and engineering safety features (ESF) instrumentation; response testing of equipment to ESF signals; reactor vessel level indication calibration; auxiliary feedwater system testing, including channel functional testing of loss of main feedwater pump signal; and diesel generator testing, including relief valve testing and essential service water valve testing.
The licensee's application for amendment was dated October 28, 1987.
~ The Need for the Pro osed Action:
The proposed amendment is needed to allow certain survei llances and tests to be delayed starting from December 31, 1987 and until the refueling outage currently scheduled to begin in ear ly 1988.
If the extension is not granted, the D.
C.
Cook Unit 2 must be shut down or placed in a condition where an unwarranted reactor trip would be increasingly possible.

The extension will allow the plant to continue operation during a period of increased demand.
Environmental Im acts of the Pro osed Action:
The proposed amendment will extend the period of certain surveillances by approximately 6 months beyond the technical specification requirement of 18 months.
The 0.
C.
Cook Unit 2 has been operating at reduced power (80K of full power) to further limit the steam generator tube degradation.
This reduced power has extended the fuel cycle and has made it necessary to conduct the surveillances either at power and increase the likelihood of inadvertent reactor trip or at an early shutdown during an increased power demand period.
The instrumentation involved has been shown in the past to be reliable and any problems that develop during the extension period will be dealt with in accordance with Technical Specification requirements.
Extending the surveillance period will not significant affect operations nor create accidents (or unwarranted transients).
Therefore, the Commission concludes that there a> e no significant radiological environmental impacts associated with the proposed amendment.
The proposed amendment does not affect nonradiological plant effluents and has no other environmental impact.
Therefore, the Commission concludes that there are no significant nonradiological environmental impacts associated with the proposed amendment.
N ternatives to the pro osed Action:
Since t.he Commi~sio>>
has concluded aha<
'here are no significant environmental effects that. would result from the proposed action, any alternatives with equal or greater environmental impacts need not be evaluated.
The bounding alternative,
- however, would be to require an early shutdown with subsequent restart to finish the fuel cycle.
This action=would create environmental impacts from the additional radioactive

wastes (reactor coolant system cleanup) generated as the result of a shutdown and would also result in increased costs for replacement power, etc., without a clear benefit from performing the surveillance tests as scheduled.
Requiring the surveillances to be performed at power could result in an inadvertent reactor trip which would have the same effect plus increasing the probability of an accident by challenging safety systems.
Alternative Use of Resources:
These actions involve no use of resources not previously considered in the Final Environmental Statement related to opera-tion of the D.
C.
Cook Nuclear Plant.
A encies and Persons Consulted:
The Commission's staff reviewed the licensee's request and did not consult other agencies or persons.
FINDING OF NO SIGNIFICANT IMPACT The Commission has determined not to prepare and environmental impact statement for the proposed amendment.
Based upon the foregoing environmental assessment, we conclude 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 October 28, 1987 which is available for public inspection at the Commission's Public Document
- Room, 17I7 H Street, N. W., Washington, D. C.,
and at the Maude Preston Palenske Memorial Library, 500 Market Street, St.

Dated at Bethesda, Maryland this 17th day of December 1987.
