Spent Fuel Heat Generation in an Independent Spent Fuel Storage 
Installation

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment draft regulatory guide (DG), DG-3050, ``Spent Fuel Heat 
Generation in an Independent Spent Fuel Storage Installation.'' This 
proposed revision (Revision 2) to RG 3.54 provides methods acceptable 
to the Nuclear Regulatory Commission (NRC) staff for calculating spent 
nuclear fuel heat generation rates for use for an independent spent 
fuel storage installation (ISFSI).

DATES: Submit comments by February 21, 2017. Comments received after 
this date will be considered if it is practical to do so, but the NRC 
is able to ensure consideration only for comments received on or before 
this date. Although a time limit is given,

B. Submitting Comments

    Please include Docket ID NRC-2016-0268 in your comment submission. 
The NRC cautions you not to include identifying or contact information 
that you do not want to be publicly disclosed in your comment 
submission. The NRC posts all comment submissions at http://www.regulations.gov as well as entering the comment submissions into 
ADAMS. The NRC does not routinely edit comment submissions to remove 
identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment submissions into ADAMS.

II. Additional Information

    The NRC is issuing for public comment a DG 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 
NRC's regulations, techniques that the staff uses in evaluating 
specific issues or postulated events, and data that the staff needs in 
its review of applications for permits and licenses.
    The DG, entitled, ``Spent Fuel Heat Generation in an Independent 
Spent Fuel Storage Installation,'' is temporarily identified by its 
task number, DG-3050. Draft Guide-3050 is proposed Revision 2 to 
Regulatory Guide (RG) 3.54, dated January 1999.
    This revision (Revision 2) presents an up-to-date methodology for 
determining heat generation rates for both PWR and BWR fuel and 
provides greater flexibility (less restrictions) than the previous 
revision. It allows loading of higher burnup fuel by using more 
accurate methods for decay heat calculations by covering a wider range 
of fuel characteristics, including operating history.

III. Backfitting and Issue Finality

    This draft regulatory guide, if finalized, would provide guidance 
to general and specific NRC part 72 licensees with respect to 
determining heat generation rates for spent fuel. Issuance of this 
draft regulatory guide, if finalized, would not constitute backfitting 
as defined in in section 72.62(a) of title 10 of the Code of Federal 
Regulations (10 CFR), which is applicable to ISFSIs. Issuance of the 
draft regulatory guide, if finalized, would also not constitute 
backfitting under 10 CFR 50.109, or otherwise be inconsistent with the 
issue finality provisions in 10 CFR part 52. The staff's position is 
based upon the following considerations.
    1. The draft regulatory guide positions, if finalized, describe a 
methodology acceptable to the NRC staff, and expressly states that 
current licensees may continue to use guidance the NRC found acceptable 
for complying with the identified regulations as long as the licensee 
does not initiate, as a voluntary matter, a change to its current 
licensing basis. Therefore, the guidance, if finalized, would not 
constitute backfitting as defined in 10 CFR 72.62(a).
    2. The NRC has no intention of imposing the positions in the draft 
regulatory guide on existing ISFSI or nuclear power plant licenses 
either now or in the future (absent a voluntary request for change from 
the licensee).
    3. The matters addressed in the regulatory guide apply equally to 
both specific licensees under part 72 as well as general licensees 
under who hold ISFSI licensees by virtue of their status as holders of 
part 50 operating licenses or as holders of part 52 combined licenses.
    4. Backfitting and issue finality do not--with limited exceptions 
not applicable here--protect current or future applicants. Applicants 
and potential applicants are not, with certain exceptions, protected by 
the backfitting provisions in 10 CFR 72.62. This is because the 
backfitting provisions in Part 72 were not intended to apply to every 
NRC action which substantially changes the expectations of current and 
future applicants.

    Dated at Rockville, Maryland, this 19th day of December, 2016.
