Office of New Reactors; Interim Staff Guidance on the Review of 
Nuclear Power Plant Designs Using a Gas Turbine Driven Standby 
Emergency Alternating Current Power System

AGENCY: Nuclear Regulatory Commission (NRC).

ACTION: Solicitation of public comment.


SUMMARY: The NRC staff is soliciting public comment on its proposed 
Interim Staff Guidance (ISG) DC/COL-ISG-021 titled ``Interim Staff 
Guidance on the Review of Nuclear Power Plant Designs Using a Gas 
Turbine Driven Standby Emergency Alternating Current Power System,'' 
(Agencywide Documents Access and Management System (ADAMS) Accession 
No. ML092640035). This ISG provides new guidance information for 
applicants submitting a combined license (COL) or design certification 
(DC) for construction and operation of new reactors submitted under 
Title 10 of the Code of Federal Regulations, Part 52. In addition, it 
supplements the guidance provided to the NRC staff in other sections of 
NUREG-0800, ``Standard Review Plan for the Review of Safety Analysis 
Reports for Nuclear Power Plants,'' March 2007, Standard Review Plan 
(SRP), Section 8.3.1 and Sections 9.5.4 through 9.5.8. The NRC staff 
issues DC/COL-ISGs to facilitate timely implementation of current staff 
guidance and to facilitate activities associated with review of 
applications for DCs and COLs by the Office of New Reactors (NRO). The 
NRC staff intends to incorporate the final approved DC/COL-ISG-021 into 
the next revision of SRP Section 8.3.1 and Sections 9.5.4 through 9.5.8 
and Regulatory Guide 1.206, ``Combined License Applications for Nuclear 
Power Plants (LWR Edition),'' June 2007.
    Background: Emergency diesel generators are widely used as the 
standby emergency power sources for the onsite alternating current (AC) 
power system. It is anticipated that new reactor designs will 
incorporate gas turbines to supply the standby emergency alternating 
current power system. This ISG document provides guidance on the 
implementation of emergency gas turbine generators (EGTGs) used as AC 
power sources to supply power to safety-related equipment or equipment 
important to safety for all operational events and during accident 
conditions. Only EGTG systems that are air cooled and diesel oil fueled 
are considered in this interim guidance.

DATES: Comments must be filed no later than 30 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-2010-0033 in the subject line of your 
comments. Comments submitted in writing or in electronic form will be 
posted on the NRC website and on the Federal rulemaking Web site 
Regulations.gov. Because 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.
