Qualification of Class 1E Connection Assemblies for Nuclear Power Generating Stations and Other Nuclear Facilities
|Publication Date:||8 February 2019|
This standard provides basic requirements, direction, and methods for qualifying Class lE connection assemblies for service in nuclear power generating stations and other nuclear facilities. These include connectors, terminations, and environmental seals in combination with related cables or wires as assemblies. Qualification of cable with connectors to this standard does not replace qualification to IEEE Std 383™-2015.2 This standard does not apply to containment electric penetrations, fire stops, in-line splices, components for service within the reactor vessel, or fiber optic connectors (refer to IEEE Std 1682™-2011 [B9]).3 The qualification requirements in this standard, when met, demonstrate and document the ability of the equipment to perform safety function(s) under applicable service conditions (including design basis events) reducing the risks of common cause equipment failures. This standard does not provide environmental stress levels and performance requirements.
NOTE-Other IEEE standards that present qualification methods for specific equipment, specific environments, or specific parts of qualification program may be used to supplement this standard, as applicable. The bibliography of IEC/IEEE 60780-323-2016 lists other standards related to equipment qualification.4
The purpose of this standard is to provide specific direction for the implementation of IEC/IEEE 60780-323-2016 for qualification as it pertains to qualification of connectors, terminations, and environmental seals (related to cables as assemblies).
