SUPPLEMENTARY INFORMATION:

Background

Section 218(a) of the Nuclear Waste Policy Act of 1982, as amended (NWPA), requires that “[t]he Secretary [of the Department of Energy (DOE)] shall establish a demonstration program, in cooperation with the private sector, for the dry storage of spent nuclear fuel at civilian nuclear power reactor sites, with the objective of establishing one or more technologies that the [Nuclear Regulatory] Commission may, by rule, approve for use at the sites of civilian nuclear power reactors without, to the maximum extent practicable, the need for additional site-specific approvals by the Commission.” Section 133 of the NWPA states, in part, that “[t]he Commission shall, by rule, establish procedures for the licensing of any technology approved by the Commission under Section 218(a) for use at the site of any civilian nuclear power reactor.”

To implement this mandate, the NRC approved dry storage of spent nuclear fuel in NRC-approved casks under a general license by publishing a final rule in 10 CFR part 72 entitled, “General License for Storage of Spent Fuel at Power Reactor Sites” (55 FR 29181; July 18, 1990). This rule also established a new subpart L within 10 CFR part 72, entitled “Approval of Spent Fuel Storage Casks” containing procedures and criteria for obtaining NRC approval of spent fuel storage cask designs. The NRC subsequently issued a final rule on December 22, 1994 (59 FR 65898), that approved the Standardized NUHOMS® System (NUHOMS®-24P and -52B) cask designs and added them to the list of NRC-approved cask designs in § 72.214 as CoC No. 1004. Amendments 3, 5, and 6, respectively, added the -61BT, -32PT, and -24PHB designs to the Standardized NUHOMS® System.

Discussion

On September 19, 2003, and as supplemented on January 22, April 21, May 28, July 6, August 16, September 17, September 23, October 8, October 11, October 26, November 29, 2004, and January 14, March 15, June 10, and July 20, 2005, the certificate holder, Transnuclear, Inc. (TN), submitted an application to the NRC to amend CoC No. 1004 to add a new spent fuel storage and transfer system, designated the NUHOMS®-24PTH System, and to modify the NUHOMS®-32PT and -24PHB dry shielded canister (DSC) designs. The NUHOMS®-24PTH System consists of new or modified components: (1) The -24PTH DSC; (2) a new -24PTH DSC basket design; (3) a modified horizontal storage module (HSM), designated the HSM-H; and (4) a modified transfer cask (TC), designated the OS 197FC TC. The NUHOMS®-24PTH System is designed to store fuel with maximum average burnup of up to 62 gigawatts-day/metric ton of uranium (GWd/MTU); maximum average initial enrichment of 5.0 weight percent; minimum cooling time of 3.0 years; and maximum heat load of 40.8 kilowatts (kW) per DSC. TS 1.2.18 and Table 1-1l are augmented to restrict the -24PTH DSC basket heat loading patterns to those analyzed in the Safety Analysis Report (SAR), and TS 1.2.17c is revised to delete the use of air for blowdown of the -24PTH DSC before drying operations. The changes to the -32PT and -24PHB systems include: (1) Revising the -32PT DSC Fuel Specification and Fuel Qualification Tables to include low enrichment and reconstituted fuel; (2) revising the -32PT DSC Fuel Specification Tables to show minimum boron loading concentration; (3) expanding the authorized contents for the -24PHB DSC; (4) revising the TC/DSC handling and lifting height specifications in TS 1.2.10 and 1.2.13; and (5) clarifying DSC surface contamination actions in TS 1.2.12. No other changes to the Standardized NUHOMS® System cask design were requested in this application. The NRC staff performed a detailed safety evaluation of the proposed CoC amendment request and found that an acceptable safety margin is maintained. In addition, the NRC staff has determined that there continues to be reasonable assurance that public health and safety and the environment will be adequately protected.

This direct final rule revises the Standardized NUHOMS® System cask design listing in § 72.214 by adding Amendment No. 8 to CoC No. 1004. The amendment consists of changes to the TS as described above. The particular TS which are changed are identified in the NRC staff's SER for Amendment No. 8.

The amended Standardized NUHOMS® System, when used in accordance with the conditions specified in the CoC, the TS, and NRC regulations, will meet the requirements of part 72; thus, adequate protection of public health and safety will continue to be ensured.

Discussion of Amendments by Section

Section 72.214 List of Approved Spent Fuel Storage Casks

Certificate No. 1004 is revised by adding the effective date of Amendment Number 8.

Procedural Background

On May 25, 2005, a direct final rule (70 FR 29931) and companion proposed rule (70 FR 30015) were published in the Federal Register, to revise the cask system listing for the TN Standardized NUHOMS® System, by adding Amendment No. 8 to the list of approved spent fuel storage casks in 10 CFR 72.214. After the rules were published, staff became aware of needed changes in the TS associated with the CoC, and on July 15, 2005, the NRC withdrew the direct final rule (70 FR 40879) and the proposed rule (70 FR 40924). This direct final rule includes the original Amendment No. 8 changes, the revised TS 1.2.17c and 1.2.18, Table 1-1l, and additional changes, as discussed above. These additional changes were originally to be addressed as a subsequent amendment. However, the withdrawal of the May 25, 2005, package allowed the staff to combine this information into Amendment No. 8. This results in a more effective and efficient use of resources.

This rule is limited to the changes contained in Amendment No. 8 to CoC No. 1004 and does not include other aspects of the Standardized NUHOMS® 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. The amendment to the rule will become effective on December 5, 2005. However, if the NRC receives significant adverse comments by October 20, 2005, then the NRC will publish a document that withdraws this action and will address the comments received in response to the proposed amendments published elsewhere in this issue of the Federal Register. 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 NRC 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 NRC 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 NRC staff to make a change (other than editorial) to the CoC or TS.

These comments will be addressed in a subsequent final rule. The NRC will not initiate a second comment period on this action.

Voluntary Consensus Standards

The National Technology Transfer Act of 1995 (Pub. L. 104-113) requires that Federal agencies use technical standards that are developed or adopted by voluntary consensus standards bodies unless the use of such a standard is inconsistent with applicable law or otherwise impractical. In this direct final rule, the NRC revises the Standardized NUHOMS® System cask design listed in § 72.214 (List of NRC-approved spent fuel storage cask designs). This action does not constitute the establishment of a standard that establishes generally applicable requirements.

Agreement State Compatibility

Under the “Policy Statement on Adequacy and Compatibility of Agreement State Programs” approved by the Commission on June 30, 1997, and published in the Federal Register on September 3, 1997 (62 FR 46517), this rule is classified as Compatibility Category “NRC.” Compatibility is not required for Category “NRC” regulations. The NRC program elements in this category are those that relate directly to areas of regulation reserved to the NRC by the Atomic Energy Act of 1954, as amended (AEA), or the provisions of Title 10 of the Code of Federal Regulations. Although an Agreement State may not adopt program elements reserved to NRC, it may wish to inform its licensees of certain requirements via a mechanism that is consistent with the particular State's administrative procedure laws but does not confer regulatory authority on the State.

Plain Language

The Presidential Memorandum dated June 1, 1998, entitled “Plain Language in Government Writing,” directed that the Government's writing be in plain language. The NRC requests comments on this direct final rule specifically with respect to the clarity and effectiveness of the language used. Comments should be sent to the address listed under the heading ADDRESSES above.

Finding of No Significant Environmental Impact: Availability

Under the National Environmental Policy Act of 1969, as amended, and the NRC regulations in subpart A of 10 CFR part 51, the NRC has determined that this rule is not a major Federal action significantly affecting the quality of the human environment and, therefore, an environmental impact statement is not required. The rule amends the CoC for the Standardized NUHOMS® System within the list of approved spent fuel storage casks that power reactor licensees can use to store spent fuel at reactor sites under a general license. The amendment adds a new spent fuel storage and transfer system, designated the NUHOMS®-24PTH System, and modifies the NUHOMS®-32PT and -24PHB DSC designs. The NUHOMS®-24PTH System consists of new or modified components: (1) The -24PTH DSC; (2) a new -24PTH DSC basket design; (3) a modified horizontal storage module, designated the HSM-H; and (4) a modified transfer cask, designated the OS 197FC TC. The NUHOMS®-24PTH System is designed to store fuel with maximum average burnup of up to 62 GWd/MTU; maximum average initial enrichment of 5.0 weight percent; minimum cooling time of 3.0 years; and maximum heat load of 40.8 kW per DSC. TS 1.2.18 and Table 1-1l are augmented to restrict the -24PTH DSC basket heat loading patterns to those analyzed in the SAR, and TS 1.2.17c is revised to delete the use of air for blowdown of the -24PTH DSC before drying operations. The changes to the -32PT and -24PHB systems include: (1) Revising the -32PT DSC Fuel Specification and Fuel Qualification Tables to include low enrichment and reconstituted fuel; (2) revising the -32PT DSC Fuel Specification Tables to show minimum boron loading concentration; (3) expanding the authorized contents for the -24PHB DSC; (4) revising the TC/DSC handling and lifting height specifications in TS 1.2.10 and 1.2.13; and (5) clarifying DSC surface contamination actions in TS 1.2.12. The EA and finding of no significant impact on which this determination is based are available for inspection at the NRC Public Document Room, 11555 Rockville Pike, Rockville, MD. Single copies of the EA and finding of no significant impact are available from Jayne M. McCausland, Office of Nuclear Material Safety and Safeguards, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, telephone [phone], e-mail [e-mail].

Paperwork Reduction Act Statement

This direct final rule does not contain a new or amended information collection requirement subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing requirements were approved by the Office of Management and Budget, Approval Number 3150-0132.

Public Protection Notification

The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid OMB control number.

Regulatory Analysis

On July 18, 1990 (55 FR 29181), the NRC issued an amendment to 10 CFR part 72 to provide for the storage of spent nuclear fuel under a general license in cask designs approved by the NRC. Any nuclear power reactor licensee can use NRC-approved cask designs to store spent nuclear fuel if it notifies the NRC in advance, spent fuel is stored under the conditions specified in the cask's CoC, and the conditions of the general license are met. A list of NRC-approved cask designs is contained in § 72.214. On December 22, 1994 (59 FR 65898), the NRC issued an amendment to part 72 that approved the Standardized NUHOMS® System (NUHOMS®-24P and -52B) by adding it to the list of NRC-approved cask designs in § 72.214. Amendments 3, 5, and 6, respectively, added the -61BT, -32PT, and -24PHB designs to the Standardized NUHOMS® System. On September 19, 2003, and as supplemented on January 22, April 21, May 28, July 6, August 16, September 17, September 23, October 8, October 11, October 26, November 29, 2004, and January 14, March 15, June 10, and July 20, 2005, the certificate holder, TN, submitted an application to the NRC to amend CoC No. 1004 to add a new spent fuel storage and transfer system, designated the NUHOMS®-24PTH System, and to modify the NUHOMS®-32PT and -24PHB DSC designs. The NUHOMS®-24PTH System consists of new or modified components: (1) The -24PTH DSC; (2) a new -24PTH DSC basket design; (3) a modified horizontal storage module, designated the HSM-H; and (4) a modified transfer cask, designated the OS 197FC TC. The NUHOMS®-24PTH System is designed to store fuel with maximum average burnup of up to 62 GWd/MTU; maximum average initial enrichment of 5.0 weight percent; minimum cooling time of 3.0 years; and maximum heat load of 40.8 kW per DSC. TS 1.2.18 and Table 1-1l are augmented to restrict the -24PTH DSC basket heat loading patterns to those analyzed in the SAR, and TS 1.2.17c is revised to delete the use of air for blowdown of the -24PTH DSC prior to drying operations. The changes to the -32PT and -24PHB systems include: (1) Revising the -32PT DSC Fuel Specification and Fuel Qualification Tables to include low enrichment and reconstituted fuel; (2) revising the -32PT DSC Fuel Specification Tables to show minimum boron loading concentration; (3) expanding the authorized contents for the -24PHB DSC; (4) revising the TC/DSC handling and lifting height specifications in TS 1.2.10 and 1.2.13; and (5) clarifying DSC surface contamination actions in TS 1.2.12.

The alternative to this action is to withhold approval of this amended cask system design and issue an exemption to each general license. This alternative would cost both the NRC and the utilities more time and money because each utility would have to pursue an exemption.

Approval of the direct final rule will eliminate this problem and is consistent with previous NRC actions. Further, the direct final rule will have no adverse effect on public health and safety. This direct final rule has no significant identifiable impact or benefit on other Government agencies. Based on this discussion of the benefits and impacts of the alternatives, the NRC concludes that the requirements of the direct final rule are commensurate with the NRC's responsibilities for public health and safety and the common defense and security. No other available alternative is believed to be as satisfactory, and thus, this action is recommended.

Regulatory Flexibility Certification

In accordance with the Regulatory Flexibility Act of 1980 (5 U.S.C. 605(b)), the NRC certifies that this rule will not, if issued, have a significant economic impact on a substantial number of small entities. This direct final rule affects only the licensing and operation of nuclear power plants, independent spent fuel storage facilities, and TN. The companies that own these plants do not fall within the scope of the definition of “small entities” set forth in the Regulatory Flexibility Act or the Small Business Size Standards set out in regulations issued by the Small Business Administration at 13 CFR part 121.

Backfit Analysis

The NRC has determined that the backfit rule (10 CFR 50.109 or 10 CFR 72.62) does not apply to this direct final rule because this amendment does not involve any provisions that would impose backfits as defined. Therefore, a backfit analysis is not required.

Congressional Review Act

In accordance with the Congressional Review Act of 1996, the NRC has determined that this action is not a major rule and has verified this determination with the Office of Information and Regulatory Affairs, Office of Management and Budget.
