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 20, section 20.1003 for Facility Operating License No. DPR-40, issued to Omaha Public Power District (OPPD/the licensee), for operation of the Fort Calhoun Station, Unit No. 1 (FCS), located in Washington County, Nebraska. Therefore, as required by 10 CFR 51.21, the NRC is issuing this environmental assessment and finding of no significant impact.
Identification of the Proposed Action
The proposed action would provide an exemption from the 10 CFR 20.1003 definition of total effective dose equivalent (TEDE), which is the sum of the deep-dose equivalent (for external exposures) and the committed effective dose equivalent (for internal exposures). The proposed exemption would change the definition of TEDE to mean the sum of the effective dose equivalent or the deep-dose equivalent (for external exposures) and the committed effective dose equivalent (for internal exposures). The staff has determined that the new method for calculating TEDE, under certain conditions, is a more accurate means of estimating worker radiation exposure.
The proposed action is in accordance with the licensee's application dated January 8, 2003.
The Need for the Proposed Action
The proposed action is needed because the current method of calculating TEDE, under certain conditions, can significantly overestimate the dose received.
Environmental Impacts of the Proposed Action
The NRC has completed its evaluation of the proposed action and concludes that revising the methodology for calculating the dose received by individuals will not have any significant environmental impacts.
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 a potential to affect any historic sites. It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, there are no significant 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 (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 FCS dated August 1972.
Agencies and Persons Consulted
On August 8, 2003, the staff consulted with the Nebraska State official, Julia Schmitt of the Nebraska Consumer Health Services Agency, 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.
