B. Submitting Comments

    Please include Docket ID NRC-2012-0280 in the subject line of your 
comment submission, in order to ensure that the NRC is able to make 
your comment submission available to the public in this docket.
    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 will post all comment submissions at http://www.regulations.gov as well as enter 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 they 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.

Background

    TSTF-535, Revision 0, is applicable to all boiling water reactor 
(BWR) power plants. The proposed change revises the Standard Technical 
Specification (STS), NUREG-1433, ``Standard Technical Specifications 
General Electric Plants BWR/4,'' and NUREG-1434, ``Standard Technical 
Specifications General Electric Plants, BWR/6.'' Specifically, the 
proposed change revises the STS definition of shutdown margin (SDM) to 
require calculation of SDM at the reactor moderator temperature 
corresponding to the most reactive state throughout the operating cycle 
(68[emsp14][deg]F or higher). The purpose is to address newer BWR fuel 
designs, which may be more reactive at shutdown temperatures above 
68[emsp14][deg]F. This STS improvement is part of the consolidated line 
item improvement process (CLIIP).

Additional Details

    This notice provides an opportunity for the public to comment on 
proposed changes to the STS after a preliminary assessment and finding 
by the NRC staff that the agency will likely offer the changes for 
adoption by licensees. This notice solicits comment on proposed changes 
to the STS, which if implemented by a licensee will modify the plant-
specific TS. The NRC staff will evaluate any comments received for the

[[Page 69508]]

proposed changes and reconsider the changes or announce the 
availability of the changes for adoption by licensees as part of the 
CLIIP. Licensees opting to apply for this TS change are responsible for 
reviewing the NRC staff's SE, and the applicable technical 
justifications, providing any necessary plant-specific information, and 
assessing the completeness and accuracy of their license amendment 
request (LAR). The NRC will process each amendment application 
responding to the notice of availability according to applicable NRC 
rules and procedures.
    The proposed change does not prevent licensees from requesting an 
alternate approach or proposing changes other than those proposed in 
TSTF-535, Revision 0. However, significant deviations from the approach 
recommended in this notice or the inclusion of additional changes to 
the license require additional NRC staff review. This may increase the 
time and resources needed for the review or result in NRC staff 
rejection of the LAR. Licensees desiring significant deviations or 
additional changes should instead submit an LAR that does not claim to 
adopt TSTF-535, Revision 0.

    Dated at Rockville, Maryland, this 2nd day of November 2012.

    For the Nuclear Regulatory Commission.

Sheldon D. Stuchell,
Acting Chief, Licensing Processes Branch, Division of Policy and 
Rulemaking, Office of Nuclear Reactor Regulation.
