equipment dynamic restraint (snubber): device that provides restraint to a component or system during the sudden application of forces, but allows essentially free motion during thermal movement.
examination: observing, visual monitoring, or measuring to determine conformance to Owner-specified requirements.
exercising: demonstration based on direct visual or mdi- red positive indications that the moving parts of a component function.
inserc’ice test: test to assess the operational readiness of a system, structure, or component after first electrical generation by nuclear heat.
instrument loop: two or more instruments or components working together to provide a single output.
instrument loop accuracy: accuracy of an instrument loop based on the square root of the sum of the squares of the inaccuracies of each instrument or component in the loop when considered separately. Alternatively, the allowable inaccuracy of the instrument loop may be based on the output for a known input into the instrument loop.
maintenance: replacement of parts, adjustments, and similar actions that do not change the design (configuration and material) of an item.
,nodifkahion: alteration in the design of a system, structure, or component.
monitoring: continuous or periodic observation or measurement to ascertain the perfonnance or obtain characteristics of a system, structure, or component.
noninfrusive testing: testing performed on a component without disassembly or disturbing the boundary of the component.
obturator: valve closure member (disk, gate, plug, etc.). operational readiness: the ability of a component to perform its specified functions.
wt’rpressure proh’ct ion: the means by which components are protected from overpressure by the use of pressure- relieving devices or other design provisions as required by the BI’V Code, Section Ill, or other applicable construct ion codes.
performance testing: a test to determine whether a system or component meets specified acceptance criteria.
plant operation: the conditions of startup, operation at power, hot standby, and reactor cooldown, as defined by plant technical specifications.
prescn’ice test: test performed after completion of construction activities related to the component and before first electrical generation by nuclear heat, or in an operating plant, before the component is initially placed in service.
pn’’n’ice lest period: the period of time following completion of construction activities related to the component and before first electrical generation by nuclear heat, in which component and system testing takes place, or in an operating plant prior to the component being initially placed in service.
pump: a mechanical device used to move fluid.
qualitatite testing: testing performed to establish parameters without determining the specific measure of the parameter.
1uantitaliz’ testing: testing performed to establish the specific measure or limit of a parameter, such as that required to establish that a parameter is within a specified range.
reference point: a point of operation at which reference values are established and inservice test parameters are measured for comparison with applicable acceptance criteria.
reference val:ws: one or more values of parameters as measured or determined when the equipment is known to be operating acceptably.
repair: the process of restoring a degraded item to its original design requirements.
routine serviciJig: performance of planned, preventive maintenance.ASME OMA CODE pdf download.
