Office of New Reactors; Proposed Standard Review Plan, Branch 
Technical Position 7-19 on Guidance for Evaluation of Diversity and 
Defense-in-Depth in Digital Computer-Based Instrumentation and Control 

AGENCY: Nuclear Regulatory Commission (NRC).

ACTION: Solicitation of public comment.


SUMMARY: The NRC staff is soliciting public comment on its Proposed 
NUREG-0800, ``Standard Review Plan for the Review of Safety Analysis 
Reports for Nuclear Power Plants,'' Branch Technical Position (BTP) 7-
19, on Guidance for Evaluation of Diversity and Defense-in-Depth in 
Digital Computer-Based Instrumentation and Control Systems (Agencywide 
Documents Access and Management System (ADAMS) Accession No. 
ML093490771). This BTP is to be cited as the acceptance criteria for 
Diversity and Defense-in-Depth (D3) in Digital Computer-Based 
Instrumentation and Control Systems in the Standard Review Plan (SRP), 
Chapter 7, for those standard reactor designs that have not been 
certified prior to the date of this BTP.
    The NRC staff issues SRPs and BTPs to facilitate timely 
implementation of current staff guidance and to facilitate activities 
associated with the review of applications for design certification 
(DC) and combined licenses (COL) by the Office of New Reactors (NRO). 
Additionally, the SRPs and BTPs are used by the Office of Nuclear 
Reactor Regulation (NRR) staff in the review of applications for 
license amendments in currently operating nuclear power plants (NPPs). 
The NRC staff will also incorporate the revised SRP section and BTP 7-
19 into the next revision of Regulatory Guide 1.206 and any related 
guidance documents.

DATES: Comments must be filed no later than 60 days from the date of 
publication of this notice in the Federal Register. Comments received 
after this date will be considered, if it is practical to do so, but 
the Commission is able to ensure consideration only for comments 
received on or before this date.

ADDRESSES: You may submit comments by any one of the following methods. 
Please include Docket ID NRC-2010-0138 in the subject line of your 
comments. Comments submitted in writing, or in electronic form, will be 
posted on the NRC Web site and on the Federal rulemaking Web site 
http://www.regulations.gov. Your comments will not be edited to remove 
any identifying or contact information, the NRC cautions you against 
including any information in your submission that you do not want to be 
publicly disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those 
persons that the NRC will not edit their comments to remove any 
identifying or contact information, and therefore, they should not 
include any information in their comments that they do not want 
publicly disclosed.

SUPPLEMENTARY INFORMATION: This SRP, NUREG-0800, has been prepared to 
establish criteria that the NRO staff use to evaluate if DC and COL 
applications meet the NRC's regulations. NRR staff also will use these 
criteria to evaluate whether licensee applications for license 
amendments for currently operating NPPs conform to NRC regulations. The 
SRP is not a substitute for the NRC's regulations, and compliance with 
it is not required. However, applicants are required to identify 
differences between design features, analytical techniques, and 
procedural measures proposed for a facility and corresponding SRP 
acceptance criteria, and evaluate how the proposed alternatives to the 
acceptance criteria provide an acceptable method of complying with the 
NRC's regulations.
    The agency posts its issued staff guidance in the agency external 
Web page (http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr0800).
    The NRC staff is issuing this notice to solicit public comments on 
proposed BTP 7-19, which is being issued for the first time. After the 
NRC staff considers any public comments, it will make a determination 
regarding proposed BTP 7-19.

    Dated at Rockville, Maryland, this 19th day of March 2010.

    For the Nuclear Regulatory Commission,
George M. Tartal,
Acting Branch Chief, Rulemaking and Guidance Development Branch, 
Division of New Reactor Licensing, Office of New Reactors.
