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.
