A RAM program is a structured methodology to identify and meet the reliability, availability, and maintainability (RAM) requirements of a power plant in the most cost- effective manner. This Standard provides requirements to govern the master planning process for a power plant RAM program. It is intended to guide the development and implementation of a comprehensive availability assurance program throughout the design, construction, and operation phases of the RAM proec1 This Standard is applicable to both new and existing Iaciliiies.
2 SCOPE
This Standard identifies the elements and responsibilities required to establish a RAM program for any power- generation facility. The program process includes
(a) establishment of RAM goals
(b) development of requirements for design, construction and commissioning, and operations
3 PURPOSE
The purpose of this Standard is to meet the owner’s power plant RAM performance goals. This Standard requires the owner to determine those goals and the criteria to achieve them. To this end, it Identifies program requirements that support effective reliability processes in design, construction and commissioning, and operations. It requires a risk-based approach to design and provides requirements to optimize performance effectively throughout the life cycle of the power plant.
4 DEFINITIONS
availability: a measure of the degree to which an item is in an operable state and can be committed at the start of a mission when the mission is called for at an unknown (random) point in time; or the ability of an item to be in a state to perform a required function under given conditions, at a given instant of time or during a given time interval, assuming that the required external resources are provided. Availability is measured by the user and is a function of how often failures occur and corrective maintenance is required, how often preventive maintenance is performed.
(m) a measurement plan to validate effectiveness
6.2.6 RAM Program Budget. A budget shall be developed to identify the cost of the RAM program as specified in the RAM program manual.
6.3 Program ImpLementation (See Figure 6.3-1)
The operator shall be responsible for implementing the RAM program including the following:
(a) initial equipment condition (baseline)
(b) procurement and installation of the software and tools
(c) populating software program(s)
(d) procurement of services, equipment, and/or tools
(e) translating operations monitoring procedures into rounds
fl development of procedures for response to out-of- specification situations
(g) metrics to monitor and gauge the plant performance against the established objectives and goals
(h) metrics to assess effectiveness of the RAM plan
(I) training of operators/maintenance
(1) execution of casks to fulfill the RAM plan
(k) new equipment (e.g., breakers, automatic valves, motors) that can self-identify critical equipment failures and alert operators remotely to failure modes via distributed digital control systems (DCS)
(I) evaluation of component system monitoring for reliability, longevity, and indirect failure risk where integrated with DCS
(m) execution of monitoring, testing, inspection, maintenance, and measurement plans
6.4 Program Revision (See Figure 6.4-1)
The owner shall periodically review and adjust the program performance. The owner shall perform additional reviews when the plant fails to meet performance expectations, the plant mission changes, or the equipment fails unacceptably. Program revision should include the following:
(a) Develop comparative performance reports based on program objectives and goals.
(b) Develop exception reports for action.
(c) Identify and evaluate high-Impact exceptions. This should include a review of plant outages or loss of production. Root cause analysis should also be considered.
(d) Review critical equipment failure trends.
(e) Compare actual to projected budget.
(f) Review, assess, and adjust the plan according to performance, and make changes in the program. (This step may be performed by the owner and/or the operator.)
