NUCLEAR REGULATORY COMMISSION
[Docket 72-1026]
Westinghouse Electric Company Issuance of Environmental
Assessment and Finding of No Significant Impact Regarding the Proposed
Exemption From Requirements of 10 CFR Part 72
By letter dated October 5, 1998, Westinghouse Electric Company
(Westinghouse or applicant) requested an exemption, pursuant to 10 CFR
72.7, from the requirements of 10 CFR 72.234(c). Westinghouse, located
in San Jose, California, is seeking Nuclear Regulatory Commission (NRC
or the Commission) approval to procure materials for and fabricate
seven W21 canisters, seven W74 canisters, and one W100 transfer cask
prior to receipt of a Certificate of Compliance (CoC) for the Wesflex
Spent Fuel Management System (Wesflex System). The Wesflex canisters
and the W100 transfer cask are basic components of the Wesflex System,
a cask system designed for the dry storage and transportation of spent
fuel. The Wesflex System is intended for use under the general license
provisions of Subpart K of 10 CFR Part 72 by Consumers Energy at the
Palisades Nuclear Plant, located in Covert, Michigan, and at the Big
Rock Point Nuclear Plant, located in Charlevoix, Michigan. The
application for the CoC was submitted by Westinghouse to the Commission
on February 3, 1998, as supplemented.
Environmental Assessment (EA)
Identification of Proposed Action
Westinghouse is seeking Commission approval to procure materials
for and fabricate seven W21 canisters, seven
[[Page 10333]]
W74 canisters, and one W100 transfer cask prior to receipt of the CoC.
The applicant is requesting an exemption from the requirements of 10
CFR 72.234(c), which states that ``Fabrication of casks under the
Certificate of Compliance must not start prior to receipt of the
Certificate of Compliance for the cask model.'' The proposed action
before the Commission is whether to grant this exemption under 10 CFR
72.7.
Need for the Proposed Action
Westinghouse requested the exemption to 10 CFR 72.234(c) to ensure
the availability of storage casks so that Consumers Energy can maintain
full core offload capability at the Palisades Nuclear Plant. Palisades
will lose full core offload capability after its planned April 2001
refueling outage. Currently, the Ventilated Storage Cask-24 (VSC-24),
fabricated by Sierra Nuclear Corporation, is used at Palisades for the
dry storage of spent fuel. However, the licensee requires another cask
option because the storage capability of the VSC-24 is limited by its
burnup and enrichment requirements. Beyond April 2001, a significant
portion of the remaining and future spent fuel inventory at Palisades
will not meet the VSC-24 burnup and enrichment limits. Already, there
are nearly 250 spent fuel assemblies at Palisades that do not qualify
for storage in the VSC-24. Further, the licensee sees the need to
replace the VSC-24 because it is not a transportable cask design.
Westinghouse is also requesting the exemption to ensure the
availability of dry storage casks at Big Rock Point to support its
decommissioning schedule. The Big Rock Point decommissioning schedule
requires that all fuel be loaded into dry storage casks by 2002.
To maintain full core offload at Palisades and to meet Big Rock
Point's decommissioning schedule, Consumers Energy anticipates that
fuel loading of Wesflex Systems would need to begin in 2001 at both
sites. Thus, at both Palisades and Big Rock Point, the availability of
the Wesflex System is needed in May 2000 to support training and dry
runs in anticipation of loading fuel in the following year. To meet
this schedule, procurement of the W100 transfer cask materials must
begin promptly and fabrication must begin by mid-1999. Further,
procurement of the W21 and W74 canister materials must begin by August
1999 and fabrication must begin by November 1999.
The Wesflex System CoC application is under consideration by the
Commission. It is anticipated that, if approved, the CoC would be
issued in late 2000.
The proposed procurement and fabrication exemption will not
authorize use of the Wesflex System to store spent fuel. That will
occur only when, and if, a CoC is issued. NRC approval of the
procurement and fabrication exemption request should not be construed
as an NRC commitment to favorably consider Westinghouse's application
for a CoC. Westinghouse will bear the risk of all activities conducted
under the exemption, including the risk that the 14 canisters and 1
transfer cask that Westinghouse plans to construct may not be usable
because they may not meet specifications or conditions placed in a CoC
that NRC may ultimately approve.
Environmental Impacts of the Proposed Action
The Environmental Assessment for the final rule, ``Storage of Spent
Nuclear Fuel in NRC-Approved Storage Casks at Nuclear Power Reactor
Sites'' (55 FR 29181 (1990)), considered the potential environmental
impacts of casks which are used to store spent fuel under a CoC and
concluded that there would be no significant environmental impacts. The
proposed action now under consideration would not permit use of the
Wesflex System, but only procurement and fabrication. There are no
radiological environmental impacts from procurement or fabrication
since the canister and transfer cask material procurement and
fabrications do not involve radioactive materials. The major non-
radiological environmental impacts involve use of natural resources due
to fabrication. Each W21 or W74 canister weighs approximately 22 tons
and is made of steel. Each W100 transfer cask weighs approximately 60
tons and is mainly made of steel. The amount of steel required for
these canisters and transfer cask is expected to have very little
impact on the steel industry. Fabrication would be at a metal
fabrication facility, not at the reactor site. Fabrication of the
canisters and transfer cask is insignificant compared to the amount of
metal fabrication performed annually in the United States. If the
canisters and transfer cask are not usable, they could be disposed of
or recycled. The amount of material disposed of is insignificant
compared to the amount of steel that is disposed of annually in the
United States. Based upon this information, the procurement of
materials and fabrication of the canisters and transfer cask will have
no significant impact on the environment since no radioactive materials
are involved, and the amount of natural resources used is minimal.
Alternative to the Proposed Action
Since there is no significant environmental impact associated with
the proposed action, any alternatives with equal or greater
environmental impact are not evaluated. The alternative to the proposed
action would be to deny approval of the exemption and, therefore, not
allow procurement of materials and fabrication of the canisters and
transfer cask until a CoC is issued. This alternative would have the
same, or greater, environmental impact.
Given that there are no significant differences in environmental
impacts between the proposed action and the alternative considered and
that the applicant has a legitimate need to procure materials and
fabricate prior to certification and is willing to assume the risk that
any material procured or any canister or transfer cask fabricated may
not be approved or may require modification, the Commission concludes
that the preferred alternative is to approve the procurement and
fabrication request and grant the exemption from the prohibition on
fabrication prior to receipt of a CoC.
Agencies and Persons Consulted
An official from the Michigan Department of Environmental Quality
was contacted about the EA for 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 an exemption from 10 CFR 72.234(c) so that Westinghouse may
procure materials for and fabricate seven W21 canisters, seven W74
canisters, and one W100 transfer cask prior to issuance of a CoC for
the Wesflex System will not significantly impact the quality of the
human environment. Accordingly, the Commission has determined not to
prepare an environmental impact statement for the proposed exemption.
The request for the exemption to 10 CFR 72.234(c) was filed by
Westinghouse on October 5, 1998, and supplemented by Consumers Energy
on November 18, 1998. For further details with respect to this action,
see the application for a CoC for the Wesflex System, dated February 3,
1998, as supplemented March 4, March 18, August 21, August 27,
September 2, and September 3, 1998. The exemption request and CoC
application are
