Draft regulatory guide; request for comment.
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 anticipated operational occurrences. This guide applies to all types of nuclear power plants that use water as the primary means of cooling.
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).
