The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an exemption from Title 10 of the Code of Federal Regulations (10 CFR) part 140, Section 140.11(a)(4) for Facility Operating License No. DPR-2, issued to Exelon Generation Company (EGC, the licensee), for operation of the Dresden Nuclear Power Station (DNPS), Unit 1, located approximately 50 miles southwest of Chicago, in Grundy County, Illinois. Therefore, as required by 10 CFR 51.21, the NRC is issuing the environmental assessment and finding of no significant impact.

Environmental Assessment

Identification of Proposed Action

The proposed action would grant an exemption from the requirement of 10 CFR 140.11(a)(4) regarding one of the two financial protection requirements.

The proposed action is in accordance with the licensee's application dated December 18, 2001, as supplement by letter dated February 13, 2002.

The Need for the Proposed Action

DNPS, Unit 1 was shut down in October 1978. On July 23, 1986, USNRC issued Amendment No. 36 to License DRP-2 for DNPS, Unit 1 changing the license to possess-but-not-operate status. The licensee at that time, Commonwealth Edison, informed the NRC that it had decided to permanently cease operations at DNPS, Unit 1, and that all fuel had been permanently removed from the reactor. In accordance with 10 CFR 50.82, upon docketing of the certifications in August 31, 1984, the facility operating license no longer authorizes the licensee to operate the reactor and to load fuel into the reactor vessel. In this permanently shutdown condition, the facility poses a reduced risk to public health and safety compared to when it was operating.

The proposed exemption is needed because the licensee's required insurance coverage exceeds the costs of potential accidents considered for a permanently defueled reactor with all spent fuel removed from the spent fuel pool. A letter received on February 13, 2002, notified the NRC that as of January 15, 2002, the DNPS, Unit 1 fuel storage pool no longer contains spent fuel assemblies. Because DNPS, Unit 1 no longer presents as great a risk as does an operating reactor plant, this reduction in risk should be reflected in the indemnification requirements to which the licensee is subject. Approval of the proposed exemption would allow a more equitable allocation of financial risk commensurate with the risks to the public.

Environmental Impacts of the Proposed Action

The NRC has completed its evaluation of the proposed action and concludes that the exemption only involves changes to indemnity insurance. The exemption would allow EGC to withdraw from participation in the secondary insurance pool based on the permanently defueled status of DNPS, Unit 1.

The proposed action will not significantly increase the probability or consequences of accidents, no changes are being made in the types of effluents that may be released off site, and there is no significant increase in occupational or public radiation exposure. Therefore, there are no significant radiological environmental impacts associated with the proposed action.

With regard to potential nonradiological impacts, the proposed action does not have the potential to affect any historic sites. It does not affect nonradiological environmental impacts associated with the proposed action.

Accordingly, the NRC concludes that there are no significant environmental impacts associated with the proposed action.

Environmental Impacts of the Alternatives to the Proposed Action

As an alternative to the proposed action, the staff considered denial of the proposed action and to require EGC to maintain the insurance coverage required of an operating plant (i.e., the “no-action” alternative). 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

The action does not involve the use of any different resource than those previously considered in the Final Environmental Statement for the Dresden Nuclear Power Station, Unit 1, dated November 1973.

Agencies and Persons Consulted

On May 9, 2002, the staff consulted with the Illinois State official, Frank Niziolek, of the Illinois Department of Nuclear Safety, regarding the environmental impact of the proposed action. The State official had no comments.

Finding of No Significant Impact

On the basis of the environmental assessment, the NRC concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the NRC has determined not to prepare an environmental impact statement for the proposed action.
