ASME QME-1-2007 pdf download.Qualification of Active Mechanical Equipment Used in Nuclear Power Plants.
QR-1000 SCOPE This Standard provides the requirements and guide- lines for the qualification of active mechanical equip- ment whose function is required to ensure the safe operation or safe shutdown of a nuclear power plant. In addition to requirements and guidelines put forth in this Standard, the active mechanical equipment shall comply with the requirements of the applicable design and construction codes and standards. This Standard does not apply to electric components suchas motors, electricvalve actuators, instrumentation, and controls, which are qualified by conformance with appropriate IEEE standards. QR-2000 PURPOSE The purpose of this Standard is to provide the require- ments and recommended practices to qualify active mechanical equipment to meet specified functional requirements during operation and during or after any postulated abnormal or accident conditions. QR-3000 REFERENCES This Section lists reference documents from which guidance, concepts, principles, practices, criteria, and parameters have been carried forward into this Standard.

(IEEE), 445 Hoes Lane, Piscataway, NJ 08854-1331 QR-4000 DEFINITIONS active mechanical equipment: mechanical equipment con- taining moving parts, which, in order to accomplish its required function as defined in the Qualification Specifi- cation, must undergo or prevent mechanical movement. This includesanyinternalcomponents orappurtenances whose failure degrades the required function of the equipment. aging: the cumulativeeffects ofoperational,environmen- tal, and systemconditions on equipmentduring a period of time up to, but not including, design basis events or the process of simulating these effects. Application Report: documentation for a specific applica- tion showing that the required pressure ratings, qualifi- cation loading levels, and operating condition capabilities are equaled or exceeded by the correspond- ing pressure ratings, qualification loadings, and operating conditioncapabilities shown inthe Functional Qualification Report. candidate equipment: active mechanical equipment to be qualified in accordance with the rules of this Standard. Class 1E: the safety classification of the electric equip- mentand systems thatare essential to emergency reactor shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal, or are other- wise essential in preventing significant release of radio- active material to the environment. component supports: structural elements that transmit loads between the components and building structure but does not include intervening elements in the compo- nentsupportload path, suchas electric motors and valve operators. demonstration: the provision of evidence to support the conclusion derived from assumed premises.
design basis event (DBE): postulated events (specified by the safety analysis of the plant) used in the design to establish the acceptable performance requirements of the structures and systems. design life: the time during which satisfactory perform- ance can be expected for a specific set of service condi- tions (the time may be specified in real time, number of operating cycles, or other performance intervals, as appropriate). Design Specification: a document prepared by the Owner or the Owner’s designee that provides a basis for the design of a system or component. essential-to-function parts/components: those parts or com- ponents of the assembly that are essential to cause, per- mit, or enable the assembly to perform the specified accident-condition function or whose failure could pre- vent the performance of this function. functionality: ability of an active component to perform the mechanical motion required to fulfill its specified function when subjected to the prescribed service condi- tions.
