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 50, section 50.60(a) for Facility Operating License No. DPR-64, issued to Entergy Nuclear Operations, Inc. (the licensee), for operation of the Indian Point Nuclear Generating Unit No. 3 (IP3), located in Westchester County, New York. 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 requirements of Start Printed Page 6749110 CFR 50.60(a) to permit the use of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), Section XI, Code Case N-640, “Alternative Requirement Fracture Toughness for Development of P-T [Pressure and Temperature] Limit Curves for ASME Section XI Division I,” in lieu of 10 CFR part 50, appendix G, paragraph I.
The proposed action is in accordance with the licensee's application dated May 28, 2003.
The Need for the Proposed Action
The proposed action provides relief from the restriction of the P-T operating window defined by the P-T operating and test curves developed in accordance with ASME Code, Section XI, Appendix G procedure. ASME Code, Section XI, Appendix G procedure was conservatively developed based on the level of knowledge existing in 1974 concerning reactor pressure vessel materials and the estimated effects of operation. Since 1974, the level of knowledge about these topics has been greatly expanded. This increased knowledge permits relaxation of the ASME Code, Section XI, Appendix G, requirements via application of ASME Code Case N-640 while maintaining the underlying purpose of the ASME Code, Section XI, Appendix G procedure. The restriction of the P-T operating and test curves developed in accordance with ASME Code, Section XI, Appendix G procedure would challenge the operations staff when operating at low temperatures.
Environmental Impacts of the Proposed Action
The NRC has completed its evaluation of the proposed action and concludes as set forth below, there are no significant environmental impacts associated with the use of the alternative analysis methods to support the revision of the P-T curves.
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 IP3, dated September 1972.
Agencies and Persons Consulted
On November 20, 2003, the staff consulted with the New York State official, Mr. John Spath of the New York State Research and Development Authority, 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.
For further details with respect to the proposed action, see the licensee's letter dated May 28, 2003. Documents may be examined, and/or copied for a fee, at the NRC's Public Document Room (PDR), located at One White Flint North, Public File Area O1 F21, 11555 Rockville Pike (first floor), Rockville, Maryland. Publicly available records will be accessible electronically from the Agencywide Documents Access and Management System (ADAMS) Public Electronic Reading Room on the Internet at the NRC Web site, http://www.nrc.gov/reading-rm/adams.html. Persons who do not have access to ADAMS or who encounter problems in accessing the documents located in ADAMS, should contact the NRC PDR Reference staff by telephone at 1-800-397-4209 or 301-415-4737, or by e-mail to firstname.lastname@example.org.Start Signature
