NUCLEAR REGULATORY COMMISSION
[NRC-2012-0152]
Design, Inspection, and Testing Criteria for Air Filtration and
Adsorption Units of Normal Atmosphere Cleanup Systems in Light-Water-
Cooled Nuclear Power Plants
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-1280,
``Design, Inspection, and Testing Criteria for Air Filtration and
Adsorption Units of Normal Atmosphere Cleanup Systems in Light-Water-
Cooled Nuclear Power Plants.'' This guide describes a method for
design, inspection, and testing of normal atmosphere cleanup systems
for controlling releases of airborne radioactive materials to the
environment during normal operations, including
[[Page 38858]]
anticipated operational occurrences. This guide applies to all types of
nuclear power plants that use water as the primary means of cooling.
DATES: Submit comments by August 27, 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.

B. Submitting Comments
Please include Docket ID NRC-2012-0152 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 in comment submissions that you do not want to be publicly
disclosed. The NRC posts all comment submissions at http://www.regulations.gov as well as enters the comment submissions into
ADAMS. The NRC does not 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 in their comment submissions
that they do not want to be publicly disclosed. Your request should
state that the NRC will not edit comment submissions to remove such
information before making the comment submissions available to the
public or entering the comment submissions into ADAMS.
II. Further 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 Normal
Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power
Plants,'' is temporarily identified by its task number, DG-1280. The
DG-1280 is proposed revision 3 of Regulatory Guide 1.140, dated June
2001. Since the last revision of RG 1.140, The American Society of
Mechanical Engineers (ASME) Committee on Nuclear Air and Gas Treatment
(CONAGT) has revised and expanded the scope of equipment covered by
ASME-AG-1, ``Code on Nuclear Air and Gas Treatment,'' which the staff
previously endorsed RG 1.140. The revision to ASME-AG-1b consolidated
some requirements from ASME-N509, ``Nuclear Power Plant Air Cleaning
Units and Components''; ASME-N510, ``Testing of Nuclear Air-Treatment
Systems''; and other documents previously endorsed by the staff in RG
1.140. In addition, CONAGT has developed and published a new standard,
ASME N511-2007, ``Inservice Testing of Nuclear Air Treatment, Heating
Ventilation and Air Conditioning Systems.'' This new standard provides
comprehensive test and inspection requirements and is written to
complement the expanded ASME-AG-1b. This revision of the regulatory
guide reflects the referenced industry standards.
III. Backfitting and Issue Finality
Because this regulatory guide reflects current regulatory practice,
it does not require a backfit analysis as described in 10 CFR
50.109(c).
Dated at Rockville, Maryland, this 21st day of June, 2012.
For the Nuclear Regulatory Commission.

Chief, Regulatory Guide Development Branch, Division of Engineering,
