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 filedby 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
