The Committee operates under proce-dur
13、esaccreditedbytheAmericanNationalStandardsInstituteasmeetingthecriteriaofconsensusprocedures for American National Standards.Due to the additional time required to consolidate the OM Code and OM-S/G documents, the2009 edition encompasses all material that would have been included in the 2007 edition
14、, 2008addenda, and 2009 addenda.The 2012 edition of Operation and Maintenance of Nuclear Power Plants includes revisions tovarious sections of Division 1, along with the addition of Mandatory Appendix V. Approvedcode cases and interpretations have also been added.The OM Committee develops, revises,
15、and maintains Codes, Standards, and Guides applicableto the safe and reliable operation and maintenance of nuclear power plants.This publication, the 2012 edition of Operation and Maintenance of Nuclear Power Plants, wasapproved by the ASME Board on Nuclear Codes and Standards.

17、pment business. This includes consideration of written requests forinterpretations, Code Cases, and revisions to Operation and Maintenance Code and developmentof new requirements as dictated by technological development. This supplement provides guid-ancetoCodeusersforsubmittingtechnicalinquiriestot
