(3) can be maintained operationally over its specified life
redundancy: a method of design where a duplicate structure, system, or component is provided such that if one fails, the redundant structure, system, or component will operate in its place to the extent that plant performance is not affected. Diversity is a similar design concept that achieves the same outcome by using alternative technical means.
reliability: the probability alan item to perform a required function under stated conditions for a specified period of time, or the ability of an Item to perform a required function under given conditions for a given time interval.
requirements: specific, quantifiable characteristics that define the success of a project. These shall define plant function, plant life, plant output, and plant performance. e.g., plant efficiency, plant staffing, plant availability, plant reliability, plant maintainability, plant financials, and other characteristics that are important to the owner. This Standard requires the owner to provide specific plant requirements that will identify the success of the project
risk: the probability of a negative event occurring.
risk assessment: the method of assessing risk and quantifying the impact to public safety and/or plant performance. A risk assessment is done with the goal of reducing the risk such that the plant can safely achieve the performance required by the owner. (See also risk.)
system: a group of structures, components, instruments, and controls that together perform a specific function(s) within a plant A system shall be capable of being defined by specific boundaries without overlap to establish clear ownership. System definitions improve the manageability of a RAM program. A system may be open or closed regarding the fluids that It contains (e.g., air, steam, water, oil, or gas such as H2). Examples include condensate system, leedwater system, service air system, boiler system, turbine system(s), control system, high-voltage system. The system definition can be either broad or very detailed, as best serves the plant and RAM program. Systems will often be defined by piping and Instrumentation drawings (P&lD). Systems must be defined for this Standard. Systems are typically identified by the plant’s designer as a part of the design process.
total ownership cost (TOC): an attempt to capture the true cost of design, development, ownership, and support of a power plant. At the individual program level, TOC is synonymous with the life-cycle cost of the system.
