[Federal Register Volume 60, Number 119 (Wednesday, June 21, 1995)] [Notices] [Pages 32354-32355] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 95-15142] ----------------------------------------------------------------------- NUCLEAR REGULATORY COMMISSION [Docket No. 50-315] Indiana Michigan Power Company; Donald C. Cook Nuclear Plant, Unit No. 1; Environmental Assessment and Finding of No Significant Impact The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption from Facility Operating License No. DPR-58, issued to Indiana Michigan Power Company, (the licensee), for operation of the D.C. Cook Nuclear Plant, Unit 1, located in Berrien County, Michigan. Environmental Assessment Identification of the Proposed Action This Environmental Assessment has been prepared to address potential environmental issues related to the licensee's application of March 17, 1995. The proposed action would exempt the licensee from the requirements of 10 CFR part 50, Appendix J, Paragraph III.D.1.(a), to the extent that a one-time interval extension for the Type A test (containment integrated leak rate test) by approximately 18 months from the September 1995 refueling outage to the 1997 refueling outage would be granted. The Need for the Proposed Action The proposed action is needed to permit the licensee to defer the Type A test from the September 1995 refueling outage to the 1997 refueling outage, thereby saving the cost of performing the test and eliminating test period from the critical path time of the outage. [[Page 32355]] Environmental Impacts of the Proposed Action The Commission has completed its evaluation of the proposed action and concludes that the proposed one-time exemption would not increase the probability or consequences of accidents previously analyzed and the proposed one-time exemption would not affect facility radiation levels or facility radiological effluents. The licensee has analyzed the results of previous Type A tests performed at the D.C. Cook Nuclear Plant to show adequate containment performance and will continue to be required to conduct the Type B and C local leak rate tests which historically have been shown to be the principal means of detecting containment leakage paths with the Type A tests confirming the Type B and C test results. It is also noted that the licensee would perform the visual containment inspection although it is only required by Appendix J to be conducted in conjunction with Type A tests. The NRC staff considers that these inspections, though limited in scope, provide an important added level of confidence in the continued integrity of the containment boundary. The change will not increase the probability or consequences of accidents, no changes are being made in the types or amounts of any effluents that may be released offsite, and there is no significant increase in the allowable individual or cumulative occupational radiation exposure. Accordingly, the Commission concludes that there are no significant radiological environmental impacts associated with the proposed action. With regard to potential nonradiological impacts, the proposed action involves features located entirely within the restricted area as defined in 10 CFR part 20. It does not affect nonradiological plant effluents and has no other environmental impact. Accordingly, the Commission concludes that there are no significant nonradiological environmental impacts associated with the proposed action. Alternatives to the Proposed Action Since the Commission has concluded there is no measurable environmental impact associated with the proposed action, any alternatives with equal or greater environmental impact need not be evaluated. As an alternative to the proposed action, the NRC staff considered denial of the proposed action. Denial of the application would result in no change in current environmental impacts. The environmental impacts of the proposed action and the alternative action are similar. Alternative Use of Resources This action does not involve the use of any resources not previously considered in the Final Environmental Statement for D.C. Cook, Units 1 and 2, dated August 1973. Agencies and Persons Consulted In accordance with its stated policy, on May 31, 1995, the NRC staff consulted with the Michigan State official, Dennis Hahn, of the Michigan Department of Public Health, Nuclear Facilities and Environmental Monitoring, regarding the environmental impact of the proposed action. The State official had no comments. Finding of No Significant Impact Based upon the environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the Commission has determined not to prepare an environmental impact statement for the proposed action. For further details with respect to the proposed action, see the licensee's letter dated March 17, 1995, which is available for public inspection at the Commission's Public Document Room, The Gelman Building, 2120 L Street, NW., Washington, DC, and at the local public document room located at the Maud Preston Palenske Memorial Library, 500 Market Street, St. Joseph, Michigan 49085. Dated at Rockville, Maryland, this 14th day of June. For the Nuclear Regulatory Commission. John B. Hickman, Project Manager, Project Directorate III-1, Division of Reactor Projects--III/IV, Office of Nuclear Reactor Regulation. [FR Doc. 95-15142 Filed 6-20-95; 8:45 am] BILLING CODE 7590-01-M
