13、mittee) of Nuclear Power Plants. The Committee operates under proce-dures accredited by the American National Standards Institute as meeting the criteria of consensusprocedures for American National Standards.Due to the additional time required to consolidate the OM Code and OM-S/G documents, the200
14、9 edition encompassed all material that would have been included in the 2007 edition, 2008addenda, and 2009 addenda.The 2012 edition of Operation and Maintenance of Nuclear Power Plants included revisionsto various sections of Division 1, along with the addition of Mandatory Appendix V. Approvedcode
15、 cases and interpretations were also added.The OM Committee develops, revises, and maintains codes, standards, and guides applicableto the safe and reliable operation and maintenance of nuclear power plants.This publication, the 2015 edition of Operation and Maintenance of Nuclear Power Plants, wasa
16、pproved by the ASME Board on Nuclear Codes and Standards. ASME OM-2015 was approvedby the American National Standards Institute on January 8, 2015.ivPREPARATION OF TECHNICAL INQUIRIESTO THE COMMITTEE ON OPERATIONAND MAINTENANCE OF NUCLEAR POWER PLANTSINTRODUCTIONThe ASME Committee on Operation and M
17、aintenance of Nuclear Power Plants meets regularlyto conduct standards development business. This includes consideration of written requests forinterpretations, Code Cases, and revisions to the Operation and Maintenance Code and develop-ment of new requirements as dictated by technological developme
18、nt. This supplement providesguidance to Code users for submitting technical inquiries to the Committee. Technical inquiriesinclude requests for revisions or additions to the Code requirements, requests for Code Cases,and requests for Code interpretations.Code Cases may be issued by the Committee whe
19、n the need is urgent. Code Cases clarify theintent of existing Code requirements or provide alternative requirements.
