NUCLEAR REGULATORY COMMISSION
[Docket No. 50-263]
Nuclear Management Company, LLC; Monticello Nuclear Generating
Plant; Environmental Assessment and Finding of No Significant Impact
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, appendix R, section III.G.2.b. for
Facility Operating License No. DPR-22, issued to Nuclear Management
Company, LLC (NMC), for operation of the Monticello Nuclear Generating
Plant (Monticello), located in Wright County, Minnesota. Therefore, as
required by 10 CFR 51.21, the NRC is issuing this environmental
assessment and finding of no significant impact.
Environmental Assessment
Identification of the Proposed Action
The proposed action would authorize an exemption from the automatic
fire suppression system requirements of 10 CFR part 50, appendix R,
section III.G.2.b. as it applies to Fire Area IV/Fire Zone 1F. Fire
Area IV/Fire Zone 1F corresponds to the Monticello torus compartment,
located at elevation 896 feet, 3 inches of the reactor building. The
proposed action is in accordance with NMC's exemption request of
September 15, 2003, as supplemented February 24, 2004.
The Need for the Proposed Action
NMC requested this exemption as a result of internal assessments of
the Monticello's Fire Protection Program. NMC determined that the
existing exemption from 10 CFR part 50 appendix R, section III.G.2.b
(granted in 1983) for the torus compartment did not bound the existing
plant configuration and the current Monticello Appendix R safe shutdown
analysis. Accordingly, the NMC resubmitted its request for a permanent
exemption for this area.
[[Page 46188]]
Environmental Impacts of the Proposed Action
The NRC staff reviewed NMC's exemption request and will issue a
safety evaluation documenting its review. The review found that the
Division 1 and Division 2 components of the core spray, residual heat
removal (RHR) cooling, suppression pool level transmitter, and
suppression pool temperature monitoring systems (SPOTMOS) are separated
in Fire Area IV/Fire Zone 1F by at least 75 feet. The NRC staff
concluded that the area wide automatic fire suppression is not
necessary to achieve the underlying purpose of appendix R, section
III.G.2.b, for the suppression pool torus area at Monticello
considering the following:
The minimal amount of fixed and transient combustibles
present;
The separation between redundant trains of core spray
valves, RHR cooling valves, and suppression pool level transmitters;
Smoke and temperature detector provisions;
The ability of SPOTMOS to continue to operate with at
least one RTD on one train in the operable-but-degraded mode for any
fire in fire zone 1F that involved both conduit trains.
The details of the NRC staff's safety evaluation will be provided
as part of the letter to NMC transmitting the NRC staff's decision on
the exemption request.
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 non-radiological impacts, the proposed
action does not have a potential to affect 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 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
Monticello dated November 1972.
Agencies and Persons Consulted
On July 22, 2004, the NRC staff consulted with the Minnesota State
official, Nancy Campbell of the Department of Commerce, 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 NMC's
exemption request of September 15, 2003, as supplemented February 24,
2004. 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,

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
