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.

Publisher: Institute of Electrical and Electronics Engineers, Inc. (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.
prototype equipment: production equipment representing the first model/type or original design/pattern. Proto- type equipment may be used for qualification testing; when selected for qualification testing, the equipment may also be called candidate equipment. qualification: thegenerationand maintenance ofevidence to ensure/demonstrate that the equipment can meet its specified service conditions in accordance with the qual- ification specification. qualification criteria: criteria developed from those spe- cific service conditions for which the equipment is to be qualified. qualification life: the period of time, prior to the start of a design basis event, for which the active mechanical equipment was demonstrated to meet the design requirements for the specified service conditions. (Note that at the end of the qualified life, the active mechanical equipment shall be capable of performing the function required for the postulated design basis and postdesign basis events.) qualification program: the overall cumulative process of specifying, conducting, and documenting the results of those activities required to qualify active mechanical equipment to perform its function in accordance with the qualification specification. Qualification Report: documentation of tests, analyses, operating experience, or any combination of these per- formed inaccordance withthis Standard orthe qualifica- tion specification that demonstrates functionality of the active mechanical equipment. Qualification Specification: the specification or portion of the Design Specification that describes the qualification requirements to be met in the qualification of the active mechanical equipment. qualified candidate equipment: equipment that has been qualified primarily by methods described in the candi- date equipment definition above met in the qualification of the active mechanical equipment.
