NUCLEAR REGULATORY COMMISSION
[Docket No. 50-482]
Wolf Creek Nuclear Operating Corporation; Wolf Creek Generating
Station Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an exemption to Facility Operating License No.
NPF-42, issued to Wolf Creek Nuclear Operating Corporation (WCNOC), for
operation of the Wolf Creek Generating Station, located in Coffey
County, Kansas.
Environmental Assessment
Identification of the Proposed Action
The proposed action would exempt WCNOC from certain requirements of
10 CFR 50.60 and 10 CFR Part 50, Appendix G. The proposed exemption
would allow WCNOC to apply American Society for Mechanical Engineers
(ASME) Code Case N-514 for determining Wolf Creek Generating Station's
cold overpressurization mitigation system (COMS) pressure setpoint.
The proposed action is in accordance with the licensee's
application for exemption dated December 29, 1998.
The Need for the Proposed Action
The proposed exemption is needed to support an amendment to the
Wolf Creek Technical Specifications which will revise the heatup,
cooldown and COMS curves. The use of ASME Code Case N-514 would allow
an increased operating band for system makeup and pressure control to
allow operational flexibility.
Environmental Impacts of the Proposed Action
The Commission has completed its evaluation of the proposed action
and concludes that application of Code Case N-514 represents a special
circumstance in accordance with 10 CFR 50.12(a)(2)(ii) on specific
exemptions, such that the specific requirements of 10 CFR 50.60 and
Appendix G are ``* * * not necessary to achieve the underlying purpose
of the rule,'' which in this case is to protect the reactor vessel from
brittle fracture.
The proposed action will not increase the probability or
consequences of accidents, no changes are being made in the types of
any 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 non-radiological impacts, the proposed
action does not involve any historic sites. It does not affect non-
radiological plant effluents and has no other environmental impact.
Therefore, there are no significant non-radiological environmental
impacts associated with the proposed action.
Accordingly, the Commission concludes that there are no significant
environmental impacts associated with the proposed action.
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
This action does not involve the use of any resources not
previously considered in the Final Environmental Statement for the Wolf
Creek Generating Station dated June 1982.
Agencies and Persons Consulted
In accordance with its stated policy, on March 5, 1999, the staff
consulted with the Kansas State official, Mr. Vick Cooper, of the
Kansas Department of Health and Environment, 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 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 December 29, 1998, 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 Emporia State University, William Allen
White Library, 1200 Commercial Street, Emporia, Kansas 66801 and
Washburn University School of Law Library, Topeka, Kansas 66621.
Dated at Rockville, Maryland, this 22nd day of April 1999.
For the Nuclear Regulatory Commission.

Project Manager, Section 2, Project Directorate IV & Decommissioning,

Regulation.
