NUCLEAR REGULATORY COMMISSION

[NRC-2011-0296]


Design, Inspection, and Testing Criteria for Air Filtration and 
Adsorption Units

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
is issuing for public comment draft regulatory guide (DG), DG-1274, 
``Design, Inspection, and Testing Criteria for Air Filtration and 
Adsorption Units of Postaccident Engineered-Safety-Feature Atmosphere 
Cleanup Systems in Light-Water-Cooled Nuclear Power Plants.'' This 
guide applies to the design, inspection, and testing of air filtration 
and iodine adsorption units of engineered-safety-feature (ESF) 
atmosphere cleanup systems in light-water-cooled nuclear power plants.

DATES: Submit comments by February 25, 2012. 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, comments and suggestions in 
connection with items for inclusion in guides currently being developed 
or improvements in all published guides are encouraged at any time.

ADDRESSES: Please include Docket ID NRC-2011-0296 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. 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. You may submit comments by any one of the following 
methods:
     Federal Rulemaking Web Site: Go to http://www.regulations.gov and search for documents filed under Docket ID NRC-
2011-0296. Address questions about NRC dockets to Carol Gallagher, 
telephone: (301) 492-3668; email: [email protected].

    You can access publicly available documents related to this 
regulatory guide using the following methods:

and have copied, for a fee, publicly available documents at the NRC's 
PDR, O1-F21, One White Flint North, 11555 Rockville Pike, Rockville, 
Maryland 20852.
     NRC's Agencywide Documents Access and Management System 
(ADAMS): Publicly available documents created or received at the NRC 
are available online in the NRC Library at http://www.nrc.gov/reading-rm/adams.html. From this page, the public can gain entry into ADAMS, 
which provides text and image files of the NRC's public documents. If 
you do not have access to ADAMS or if there are problems in accessing 
the documents located in ADAMS, contact the NRC's PDR reference staff 
at 1 (800) 397-4209, (301) 415-4737, or by email to 
[email protected]. DG-1278 is available electronically under ADAMS 
Accession Number ML11244A045. The regulatory analysis is available 
under ADAMS Accession Number ML11244A050.
     NRC's Public Web Site: Electronic copies of DG-1274 are 
also available through the NRC's public Web site under Draft Regulatory 
Guides in the ``Regulatory Guides'' collection of the NRC's Library at 
http://www.nrc.gov/reading-rm/doc-collections/.
     Federal Rulemaking Web Site: Public comments and 
supporting materials related to this regulatory guide can be found at

SUPPLEMENTARY INFORMATION: The NRC is issuing for public comment a 
draft guide in the NRC's ``Regulatory Guide'' series. This series was 
developed to describe and make available to the public such information 
as 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 problems or postulated accidents, and data that 
the staff needs in its review of applications for permits and licenses.
    The draft regulatory guide, entitled, ``Design, Inspection, and 
Testing Criteria for Air Filtration and Adsorption Units of 
Postaccident Engineered-Safety-Feature Atmosphere Cleanup Systems in 
Light-Water-Cooled Nuclear Power Plants,'' is temporarily identified by 
its task number, DG-1274. The DG-1274 is proposed revision 4 of 
Regulatory Guide 1.52, dated June 2001.
    This guide provides a method that the NRC considers acceptable to 
implement Title 10, of the Code of Federal Regulations, part 50, 
``Domestic Licensing of Production and Utilization Facilities,'' 
Appendix A, ``General Design Criteria for Nuclear Power Plants,'' as it 
applies to the design, inspection, and testing of air filtration and 
iodine adsorption units of engineered-safety-feature (ESF) atmosphere 
cleanup systems in light-water-cooled nuclear power plants. For the 
purposes of this guide, ESF atmosphere cleanup systems are those 
systems that are credited in the licensee's current design-basis 
accident (DBA) analysis, as described in the safety analysis report 
(SAR), or those systems that the licensee has described in the SAR as 
ESF atmosphere cleanup systems. This guide addresses ESF atmosphere 
cleanup systems, including the various components and ductwork, in the 
postulated DBA environment.

    For the Nuclear Regulatory Commission.

    Dated at Rockville, Maryland this 21st day of December, 2011.
Harriet Karagiannis,
Acting Chief, Regulatory Guide Development Branch, Division of 
Engineering, Office of Nuclear Regulatory Research.
