21、 described in ASME RAM-1. This Standard describes one way to imple-ment a RAM program in an existing power plant.The concept of RAM is based on the fundamental principle that power plant availability is a necessary goal.

Risk calculations, expert opinion, andfailure experience identify risks inherent with the design, which are then used

24、to develop an effective scheduled main-tenance and monitoring program.TraditionaltermsaddressingRAM-relatedworkincludepreventivemaintenance,scheduledmaintenance,operationsmonitoring, and rounds. This Standard assists those responsible for programs that manage equipment assets byproviding directly ac

It can also support the development of efficient, reliable maintenance for new designs.This Standard assumes plant practices follow manuals, industry standards, and related

26、 asset management guidance.The RAM program is intended to control practices that influence results, following established industry practices. ThisRAM Standard does not cover human performance.ASME RAM-22016 was approved by the RAM Standards Committee, under the jurisdiction of the Board onStandardiz

44、RODUCTIONA reliability, availability, and maintainability (RAM)program is a structured way to identify and deliver theRAMrequirementsofapowerplantinthemostcost-effec-tive manner. This Standard provides guidance for theprogram implementation portion of the RAM processdescribed in ASME RAM-1. It is in

45、tended to implementa comprehensive availability assurance program. ThisStandard is intended for existing facilities.2 SCOPEThis Standard amplifies and clarifies the requirementsof ASME RAM-1 for implementing a RAM program for apower-generation facility. This Standard assists in devel-oping program g

46、oals, identifying a master equipment list(MEL) to load into the enterprise asset managementsystem (EAMS), and populating scheduling systemswith finished content as complete work orders that arereadytoperformwork.ARAMprogramincludeshierarch-ical breakdown of the facility, tagging of equipment (i.e.,c

47、omponents), risk categorization of systems and equip-menttags,developmentofcommonstandardsforcompo-nents, and customization for similar context locations inthe plant. This Standard finalizes work organization astask lists in work orders, routes, and rounds. It providesa process to implement ASME RAM

48、-1 based on termi-nology and methodology used in power plants.This Standard addresses the following:(a) equipment assessment for risk(b) asset tagging(c) template selection and application(d) equipment asset management software(e) development and organization of work (e.g., devel-opment of operating

49、 procedures, rounds, and workorders)(f) RAM program plans(g) training required to implement the program3 PURPOSEThe purpose of this Standard is to provide informationto enable plant personnel to develop an effective RAMprocess in accordance with ASME RAM-1. An effectiveRAM program ensures that critical plant equipmentperforms cost-effectively as intended by design. ThisStandard provides an all-encompassing RAM supportprocess that develops simple, clearly worded RAManalysis in accordance with ASME RAM-1.4 DEFINITIONSThefollowingisalistoftermsrelatingtotheimplemen-tation and use of RAM
