NUCLEAR REGULATORY COMMISSION
[Docket No. 50-382]
Entergy Operations Inc.; Waterford Steam Electric Station, Unit
3; Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of exemptions from Title 10 of the Code of Federal Regulations
(10 CFR) Part 50, Section 50.46 and Appendix K, for Facility Operating
License No. NPF-38, issued to Entergy Operations Inc. (the licensee),
for operation of the Waterford Steam Electric Station, Unit 3
(Waterford 3), located in St. Charles Parish, Louisiana. 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 exempt Waterford 3 from the requirements
of 10 CFR Part 50, Section 50.46 and Appendix K, to allow the use of up
to four Lead Test Assemblies (LTAs) fabricated with Optimized
ZIRLOTM, a cladding material that contains a nominally lower
tin content than previously approved cladding materials.
The proposed action is in accordance with the licensee's
application dated April 30, 2004.
The Need for the Proposed Action
As the nuclear industry pursues longer operating cycles with
increased fuel discharge burnup and more aggressive fuel management,
the corrosion performance requirements for the nuclear fuel cladding
become more demanding. Available industry data from the American
Nuclear Society, the International Atomic Energy Agency, the Electric
Power Research Institute, and Westinghouse Electric Corporation
(Westinghouse) indicate that corrosion resistance improves for cladding
with a lower tin content. The optimum tin level provides a reduced
corrosion rate while maintaining the benefits of mechanical
strengthening and resistance to accelerated corrosion from abnormal
chemistry conditions. In addition, fuel rod internal pressures
(resulting from the increased fuel duty, use of integral fuel burnable
absorbers and corrosion/temperature feedback effects) have become more
limiting with respect to fuel rod design criteria. Reducing the
associated corrosion buildup, and thus, minimizing temperature feedback
effects, provides additional margin to fuel rod internal pressure
design criteria.
To meet these needs, Westinghouse developed a LTA program in
cooperation with Entergy Operations Inc., which includes a fuel
cladding with a tin content lower than the currently licensed range for
ZIRLOTM. The NRC's regulations in 10 CFR 50.46 and Appendix
K, make no provision for use of fuel rods clad in a material other than
Zircalloy or ZIRLOTM. The licensee has requested the use of
up to four LTAs with a tin composition that is less than that specified
in the licensing basis for ZIRLOTM, as defined in
Westinghouse design specifications. Therefore, use of the LTAs calls
for exemptions from 10 CFR 50.46 and Appendix K.
Environmental Impacts of the Proposed Action
The NRC staff has completed its evaluation of the proposed action
and concludes that the proposed exemptions would not increase the
probability or consequences of accidents previously analyzed and would
not affect facility radiation levels or facility radiological
effluents.
[[Page 31849]]
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 offsite, 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 staff 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 resources than
those previously considered in the Final Environmental Statement for
Waterford 3, dated September 1981.
Agencies and Persons Consulted
On May 11, 2004, the staff consulted with the Louisiana State
official, Mr. Prosanta Chowdhury, of the Louisiana Department of
Environmental Protection, 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 April 30, 2004 (ADAMS Accession Number
ML041250184). 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)
