The OM Committee develops, revises,and maintains
13、codes, standards, and guides applicable to the safe and reliable operation andmaintenance of nuclear power plants. The Committee operates under procedures accredited bythe American National Standards Institute as meeting the criteria of consensus procedures forAmerican National Standards.This public
14、ation, the 2017 edition of Operation and Maintenance of Nuclear Power Plants, wasapproved by the ASME Board on Nuclear Codes and Standards. ASME OM-2017 was approvedby the American National Standards Institute on May 4, 2017.ivPREPARATION OF TECHNICAL INQUIRIESTO THE COMMITTEE ON OPERATIONAND MAINTE
15、NANCE OF NUCLEAR POWER PLANTSINTRODUCTIONThe ASME Committee on Operation and Maintenance 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 Co
16、de and develop-ment of new requirements as dictated by technological development. 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 r
17、equests for Code interpretations.Code Cases may be issued by the Committee when the need is urgent. Code Cases clarify theintent of existing Code requirements or provide alternative requirements. Code Cases are writtenas a question and a reply, and are usually intended to be incorporated into the Co
18、de at a laterdate. Code interpretations provide the meaning or the intent of existing requirements in the Codeand are also presented as a question and reply. Both Code Cases and Code interpretations arepublished by the Committee.The Code requirements, Code Cases, and Code interpretations established
19、 by the Committeeare not to be considered as approving, recommending, certifying, or endorsing any proprietaryor specific design or as limiting in any way the freedom of manufacturers or constructors tochoose any method of design or any form of construction that conforms to the Code requirements.Mor
20、eover, ASME does not act as a consultant on specific engineering problems or on thegeneral application or understanding of the Code requirements. If, based on the inquiry informa-tion submitted, it is the opinion of the Committee that the inquirer should seek assistance, theinquiry will be returned
21、with the recommendation that such assistance be obtained.As an alternate to the requirements of this supplement, members of the Committee and itssubcommittees, subgroups, and working groups may introduce requests for Code revisions oradditions, Code Cases, and Code interpretations at their respectiv
22、e Committee meetings or maysubmit such requests to the secretary of a subcommittee, subgroup, or working group.AllinquiriesthatdonotprovidetheinformationneededfortheCommitteesfullunderstandingwill be returned.INQUIRY FORMATSubmittals to the Committee shall include:(a) Purpose.

Huang K. ZhengP. Lio Z. ZhouPREFACEGENERALIn 2008, the OM Committee directed that the two separately publ
48、ished OM Code and theOM Standards and Guides (OM-S/G) publications be combined into one document. This wasdone to ensure all of our standards and guides documents were readily available to users of theOM Code products. Some of the standards and guides were originally developed as part of thecurrent
49、operating nuclear power plants preoperational testing program conducted during the1970s and 1980s. These standards and guides will be useful for power uprate projects and fornew reactor design plant construction. Combining the OM Code and OM-S/G into one documentmakes the publication schedules for the Committee more efficient and easier to track.ORGANIZATIONThe consolidated code, standards, and guides for nuclear power plants, titled Operation andMaintenance of Nuclear Power Plants, are arranged into three distinct divisions. The titles ofsome of the sections were shortened to sim
