NUCLEAR REGULATORY COMMISSION

[Docket No. 50-483]


Union Electric Co., Callaway Plant; 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. NPF-30, issued to Union Electric Company, (the licensee), for the 
Callaway Plant, located in Callaway County, Missouri.

Environmental Assessment

Identification of Proposed Action

    The proposed action would grant an exemption from a requirement of 
Section III.D.1.(a) of Appendix J to 10 CFR Part 50, which requires a 
set of three Type A tests (Containment Integrated Leakage Rate Test or 
CILRT) be performed, at approximately equal intervals during each 10-
year service period. This licensee request for an exemption would defer 
the next scheduled containment integrated leak rate test for one 
outage, from Refuel 7 to Refuel 8.
    The proposed action is in accordance with the licensee's request 
for exemption dated December 9, 1994, as supplemented by letter dated 
January 27, 1995.

The Need for the Proposed Action

    The proposed action is needed because the licensee's current 
schedule would require the third CILRT to be performed during Refuel 7 
(March 1995). Minimal safety benefit would be realized by performing 
the scheduled CILRT, since the majority of primary containment leakage 
has previously been identified through the biennial performance of the 
Local Leak Rate Test (LLRT). Without this exemption, the licensee would 
incur additional personnel radiation exposure during system 
reconfigurations, and instrumentation setup and restoration.

Environmental Impacts of the Proposed Action

    The Commission has completed its evaluation of the proposed action 
and concludes that the exemption would not significantly increase the 
probability or amount of expected containment leakage, and that 
containment integrity would thus be maintained.
    The change will not increase the probability or consequences of 
accidents, no changes are being made in the types 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 does involve 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.

Alternative to the Proposed Action

    Since the Commission has concluded there is no measurable 
environmental impacts 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 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 related to 
the operation of Callaway Plant, Unit No. 1,'' dated January 1982.

Agencies and Persons Consulted

    In accordance with its stated policy, the staff consulted with the 
Missouri State official 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 this proposed action, see the 
licensee's letters dated December 9, 1994, and January 27, 1995, which 
are 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 [[Page 15612]] Callaway 
County Public Library, 710 Court Street, Fulton, Missouri 65251.

    Dated at Rockville, Maryland, this 17th day of March, 1995.

    For the Nuclear Regulatory Commission.

Project Manager, Project Directorate III-3, Division of Reactor 
Projects--III/IV, Office of Nuclear Reactor Regulation.
