01-21935. List of Approved Spent Fuel Storage Casks: NAC-MPC Revision

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Proposed rule.

SUMMARY:

The Nuclear Regulatory Commission (NRC) is proposing to amend its regulations revising the NAC International, Inc., NAC-MPC cask system listing within the “List of Approved Spent Fuel Storage Casks” to include Amendment No. 1 to the Certificate of Compliance. Amendment No. 1 would modify the present cask system design to permit a licensee to use an alternate fuel basket design with enlarged fuel tubes in corner locations; increase the operational time limits provided in the Technical Specifications (TS) for canister loading, closure, and transfer when canister heat loads are lower than design basis heat loads; revise the canister surface contamination limits in TS to maintain worker dose as low as is reasonably achievable (ALARA); and revise some drawings to reflect changes identified during cask and component fabrication under a general license.

DATES:

Comments on the proposed rule must be received on or before October 1, 2001.

ADDRESSES:

Submit comments to: Secretary, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, Attn: Rulemakings and Adjudications Staff.

SUPPLEMENTARY INFORMATION:

For additional information see the direct final rule published in the final rules section of this Federal Register.

Procedural Background

This rule is limited to the changes contained in Amendment 1 to Certificate of Compliance Number (CoC No.) 1025 and does not include other aspects of the NAC-MPC cask system design. The NRC is using the “direct final rule procedure” to issue this amendment because it represents a limited and routine change to an existing CoC that is expected to be noncontroversial. Adequate protection of public health and safety continues to be ensured.

Because NRC considers this action noncontroversial and routine, the proposed rule is being published concurrently with a direct final rule. The direct final rule will become effective on November 15, 2001. However, if the NRC receives significant adverse comments on the direct final rule by October 1, 2001, then the NRC will publish a document to withdraw the direct final rule. A significant adverse comment is a comment where the commenter explains why the rule would be inappropriate, including challenges to the rule's underlying premise or approach, or would be ineffective or unacceptable without a change. A comment is adverse and significant if:

(1) The comment opposes the rule and provides a reason sufficient to require a substantive response in a notice-and-comment process. For example, in a substantive response:

(a) The comment causes the staff to reevaluate (or reconsider) its position or conduct additional analysis;

(b) The comment raises an issue serious enough to warrant a substantive response to clarify or complete the record; or

(c) The comment raises a relevant issue that was not previously addressed or considered by the staff.

(2) The comment proposes a change or an addition to the rule, and it is apparent that the rule would be ineffective or unacceptable without incorporation of the change or addition.

(3) The comment causes the staff to make a change to the CoC or TS.

If the direct final rule is withdrawn, the NRC will address the comments received in response to the proposed revisions in a subsequent final rule. Absent significant modifications to the proposed revisions requiring republication, the NRC will not initiate a second comment period for this action if the direct final rule is withdrawn.
