NUCLEAR REGULATORY COMMISSION
[NRC-2021-0065]
Fresh and Spent Fuel Pool Criticality Analyses
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing a new
Regulatory Guide (RG) 1.240, ``Fresh and Spent Fuel Pool Criticality
Analyses.'' This regulatory guide (RG) describes an approach that the
staff of the U.S. Nuclear Regulatory Commission (NRC) considers
acceptable to demonstrate that NRC regulatory requirements are met for
subcriticality of fuel assemblies stored in fresh fuel vaults and spent
fuel pools at light-water reactor (LWR) power plants. It endorses, with
clarifications and exceptions, the Nuclear Energy Institute (NEI)
guidance document NEI 12 16, ``Guidance for Performing Criticality
Analyses of Fuel Storage at Light Water Reactor Power Plants,''
Revision 4.
DATES: RG 1.240 is available on March 10, 2021.

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC is issuing a new guide in the NRC's ``Regulatory Guide''
series. This series was developed to describe and make available to the
public information regarding methods that are acceptable to the NRC
staff for implementing specific parts of the agency's regulations,
techniques that the NRC staff uses in evaluating specific issues or
postulated events, and data that the NRC staff needs in its review of
applications for permits and licenses.
II. Additional Information
RG 1.240 was issued with a temporary identification of Draft
Regulatory Guide, (DG)-1373.The NRC published a notice of the
availability of DG-1373 in the Federal Register on September 8, 2020
(85 FR 55522) for a 45-day public comment period. The public comment
period closed on October 23, 2020. Public comments on DG-1373 and the
staff responses to the public comments are available under ADAMS under
Accession No. ML20356A123.
III. Congressional Review Act
This RG is a rule as defined in the Congressional Review Act (5
U.S.C. 801-808). However, the Office of Management and Budget has not
found it to be a major rule as defined in the Congressional Review Act.
IV. Backfitting, Forward Fitting and Issue Finality
New Regulatory Guide (RG) 1.240 does not constitute backfitting as
defined in 10 CFR 50.109, ``Backfitting,'' and as described in NRC
Management Directive (MD) 8.4, ``Management of Backfitting, Forward
Fitting, Issue Finality, and Information Requests''; constitute forward
fitting as that term is defined and described in MD 8.4; or affect the
issue finality of any approval issued under 10 CFR part 52. As
explained in new RG 1.240, applicants and licensees would not be
required to comply with the positions set forth in the RG.
