The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status.

The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Nuclear Regulatory Commission.
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is proposing to amend its spent fuel storage cask regulations by revising the Transnuclear, Inc. (TN) NUHOMS® HD System listing within the “List of Approved Spent Fuel Storage Casks” to include Amendment No. 1 to Certificate of Compliance (CoC) Number 1030. Amendment No. 1 would revise the definitions for Damaged Fuel Assembly and Transfer Operations; add definitions for Fuel Class and Reconstituted Fuel Assembly; add Combustion Engineering 16x16 class fuel assemblies as authorized contents; reduce the minimum off-normal ambient temperature from −20 °F to −21 °F; expand the authorized contents of the NUHOMS® HD System to include pressurized water reactor fuel assemblies with control components; reduce the minimum initial enrichment of fuel assemblies from 1.5 weight percent uranium-235 to 0.2 weight percent uranium-235; clarify the requirements of reconstituted fuel assemblies; add requirements to qualify metal matrix composite neutron absorbers with integral aluminum cladding; clarify the requirements for neutron absorber tests; delete use of nitrogen for draining the water from the dry shielded canister (DSC), and allow only helium as a cover gas during DSC cavity water removal operations; and make corresponding changes to the technical specifications (TS).
Comments on the proposed rule must be received on or before February 14, 2011.

For additional information, see the Direct Final Rule published in the Rules and Regulations section of this Federal Register.
On May 6 and 7, 2010, respectively, a direct final rule (75 FR 24786) and companion proposed rule (75 FR 25120) were published in the Federal Register to revise the cask system listing for the TN NUHOMS® HD System by adding Amendment No. 1 to the list of approved spent fuel storage casks in Title 10 of the Code of Federal Regulations (10 CFR) 72.214. After the rules were published, the applicant identified that a certain TS for Boral characterization (TS 4.3.1, “Neutron Absorber Tests”) was not written precisely and in a manner that could be readily and demonstrably implemented. On July 16, 2010, the NRC withdrew the direct final rule (75 FR 41369) and the companion proposed rule (75 FR 41404).The applicant submitted revised language for TS 4.3.1 (and Final Safety Analysis Report (FSAR) sections incorporated into the TS by reference) on July 26 and August 24, 2010, which NRC staff reviewed and found to be acceptable. This proposed rule includes the original Amendment No. 1 changes and the revised TS 4.3.1 and FSAR sections incorporated into the TS by reference.
This rule is limited to the changes contained in Amendment No. 1 to CoC No. 1030 and does not include other aspects of the NUHOMS® HD System design. Because NRC considers this action noncontroversial and routine, the NRC is publishing this proposed rule concurrently as a direct final rule in the Rules and Regulations section of this Federal Register. Adequate protection of public health and safety continues to be ensured. The direct final rule will become effective on March 29, 2011. However, if the NRC receives significant adverse comments on the direct final rule by February 14, 2011, then the NRC will publish a document that withdraws the direct final rule. 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 on this action in the event the direct final rule is withdrawn.
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, a substantive response is required when:
(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 rule, CoC, or TS.
