The RAM program owner shall document the key program elements j(a) through (j)J and their contributions to the RAM program. Where program elements to implement the RAM program are not complete, the RAM program owners and staff shall develop them to support necessary work.
7.1 Scoping of Equipment
Systems that provide critical plant functions determine the scope of the RAM program, and thus the work specified by the RAM program is critical. RAM programs address, at a minimum, all critical systems, equipment, and parts. Equipment scope review starts with the plant’s MEL (or registry) — a comprehensive list of installed equipment. The RAM program shall review all MEL equipment for scope inclusion. The order of review should be by system, component (including type), and group, or any logical combination of these that leads to a complete RAM program. In the end, all equipment reviewed is either in or out of the RAM scope, classified by criticality. “In scope” equipment is equipment that shall be considered for scheduled maintenance or predictive maintenance tasks based on risk; “out of scope” equipment is excluded from specific direct, scheduled maintenance, or predictive maintenance tasks in a RAM support system.
7.2 Systems Risk Categorization
Risk categorization helps rank (classil,) critical equipment by contexi This ranking brings focus to the equipment by level of risk. Classifying risk differentiates the levels of work on the same order, improving decision- making when budget limits force work-order tasks to compete. The RAM program shall identify each safety, production, and cost impact category based on consequence, and shall base categorization of critical” on criticality of the function provided, using direct failure (DF) criteria.
The RAM program shall develop a criteria scheme and apply hierarchy levels, using OF criteria. The following table provides example relative values for the purposes of risk caterorization. The RAM program may use any risk subcategories or criteria scheme (qualitative values) as long as it ranks risk in the relative priority shown in the table. Of the risk categories shown in the table, safety, production, and cost are required (in that order).
