NUCLEAR REGULATORY COMMISSION
[Docket 72-31]
Yankee Atomic Electric Company, Independent Spent Fuel Storage
Installation; Issuance of Environmental Assessment and Finding of No
Significant Impact for a Proposed Exemption
The U.S. Nuclear Regulatory Commission (NRC or Commission) is
considering issuance of an exemption to Yankee Atomic Electric Company
(YAEC or licensee), pursuant to 10 CFR 72.7, from specific provisions
of 10 CFR 72.212(a)(2), 72.212(b)(2)(i)(A), and 10 CFR 72.214. The
licensee is planning to use the NAC-MPC storage system to store spent
nuclear fuel from the decommissioning reactor. The requested exemption
would allow YAEC to deviate from the approved contents specified in the
NAC-MPC Certificate of Compliance No. 1025 (CoC or Certificate) to
store: (1) Fuel with assembly weights up to 950 pounds; (2) fuel
assemblies with unique design features; (3) non-intact fuel in damaged
fuel cans; and (4) specific re-caged fuel assemblies in the NAC-MPC dry
spent fuel storage systems at the Yankee Nuclear Power Station.
In a letter dated May 15, 2002, the designer of the NAC-MPC system,
NAC International, requested an amendment to CoC No. 1025 to
incorporate the additional fuel assembly configurations as approved
contents for the storage system. That request was supplemented on
October 3, 2002. The information provided in the amendment request, as
supplemented, corresponds with the YAEC exemption request and provides
the safety basis for storing these additional fuel assembly
configurations.
Environmental Assessment (EA)
Identification of Proposed Action
By letter dated October 10, 2002, YAEC requested an exemption from
the requirements of 10 CFR 72.212(a)(2), 72.212(b)(2)(i)(A), and 10 CFR
72.214 to deviate from the approved contents specified in CoC No. 1025
for the NAC-MPC storage system. YAEC has informed the NRC of its plans
to store spent nuclear fuel under the general licensing provisions of
10 CFR Part 72. The licensee has begun loading spent fuel into the NAC-
MPC system at an Independent Spent Fuel Storage Installation located at
the Yankee Nuclear Power Station near Rowe, Massachusetts.
By exempting YAEC from 10 CFR 72.212(a)(2), 72.212(b)(2)(i)(A), and
10 CFR 72.214, YAEC will be authorized to store additional specific
fuel assembly configurations.
The proposed action before the Commission is whether to grant this
exemption under 10 CFR 72.7. The NRC staff has reviewed the exemption
request and determined that storage of the additional fuel assembly
configurations are consistent with the safety analyses previously
reviewed for the NAC-MPC system, and would have no impact on the design
basis and would not be inimical to public health and safety.
Need for the Proposed Action
YAEC completed loading the first NAC-MPC at the Yankee Nuclear
Power Station on June 26, 2002. The licensee is proceeding with
unloading of fuel assemblies from the spent fuel pool and loading of
the assemblies into additional NAC-MPC systems. The spent fuel pool
uses a two tier rack system for fuel storage. The licensee has
completed removal of all of the fuel from the upper rack, which has
enabled a detailed inspection of the fuel stored in the lower rack. The
licensee identified some fuel assembly types and configurations that
were not addressed in the NAC-MPC storage system Final Safety Analysis
Report. This prompted the NAC-MPC designer to submit an amendment
application to NRC for the NAC-MPC CoC to incorporate the additional
fuel configurations identified in the lower pool rack.
YAEC requested this exemption to store the additional fuel assembly
configurations in an effort to continue the removal of spent fuel from
the spent fuel pool into the NAC-MPC storage systems using the same
experienced and trained individuals involved in loading the previous
NAC-MPC systems. The exemption would likely minimize personnel exposure
by continuing to use the same individuals and by implementing lessons
learned from the previous loading activities.
Environmental Impacts of the Proposed Action
YAEC requested the exemption to store additional fuel assembly
configurations to enable transfer of all spent fuel from the spent fuel
pool to the NAC-MPC dry spent fuel storage system. The staff performed
a safety evaluation of the proposed exemption. NRC staff reviewed the
analysis provided in the NAC-MPC amendment application addressing
storage of additional specific fuel assembly configurations. The safety
evaluation performed by the staff concludes that the NRC has reasonable
assurance that storage of the additional fuel configurations has
minimal impact on off-site doses, results in a dose savings to workers,
and meets the requirements of 10 CFR 72.104, 10 CFR 72.106 and 10 CFR
20.1301, and is therefore acceptable.
Therefore, the environmental impact of storing the additional
specific fuel assemblies is no greater than the environmental impact
already assessed in the initial rulemaking for the NAC-MPC storage
system (65 FR 12444, dated March 9, 2000).
The proposed action will not significantly increase the probability
or consequences of the analyzed accidents, no changes are being made to
the types of effluents that may be released offsite, and there is no
significant increase in occupational or public radiation
[[Page 69052]]
exposure. Therefore, there are no significant radiological
environmental impacts associated with the proposed action. Therefore,
the staff has determined that there is no reduction in the ability of
the system to perform its safety function, nor significant
environmental impacts, as a result of storing the additional fuel
assembly configurations.
Alternative to the Proposed Action
Since there is no significant environment impact associated with
the proposed action, alternatives with equal or greater environmental
impact are not evaluated. The alternative to the proposed action would
be to deny approval of the exemption. Denial of the exemption request
will have the same environmental impact, but would result in a
potential dose increase to workers involved in cask loading activities.
Agencies and Persons Consulted
On November 4, 2002, Mr. Jim Muckerheide, Nuclear Engineer, Nuclear
Safety of the Massachusetts Emergency Management Agency was contacted
about the proposed action and had no comments.
Finding of No Significant Impact
The environmental impacts of the proposed action have been reviewed
in accordance with the requirements set forth in 10 CFR part 51. Based
upon the foregoing EA, the Commission finds that the proposed action of
granting the exemption from 10 CFR 72.212(a)(2), 72.212(b)(2)(i)(A),
and 10 CFR 72.214 and allowing YAEC to store additional specific fuel
assembly configurations in the NAC-MPC storage system will not
significantly impact the quality of the human environment. Accordingly,
the Commission has determined that an environmental impact statement
for the proposed exemption is not warranted.
The request for exemption was docketed under 10 CFR Part 72, Docket
72-31. For further details with respect to this action, see the
exemption request dated October 10, 2002. The NRC maintains an
Agencywide Documents Access and Management System (ADAMS), which
provides text and image files of NRC's public documents. These
documents may be accessed through the NRC's Public Electronic Reading
Room on the Internet at http://www.nrc.gov/NRC/ADAMS/index.html. If you
