Description / Abstract:

This Standard establishes the requirements for functional qualification of power operated active valve assemblies for nuclear power plants. It is not intended that this Standard be applied to power operated relief valves and self-operated valves such as check and pressure relief valves. It is the responsibility of the plant owner or his designee to identify those active valves which require qualification under this Standard and to identify the functional qualification requirements, as associated with Annexes A through H, which shall be met.

Functional qualification of a parent valve assembly consists of testing as specified herein to demonstrate that a valve assembly can perform its required function under test conditions. Annex J is a guide to provide functional qualification of a candidate valve assembly by analyses that demonstrate design similarity to a parent valve assembly. Any use of Annex J for qualification of a candidate valve for a specific application in a nuclear power plant shall be the responsibility of the plant owner or his designee.

Qualification testing, inspecting, and reporting as specified herein shall be performance in accordance with the applicable requirements of ANWASME NQA-1 or its equivalent.

A Functional Qualification Reports(s) is required to document compliance with this Standard. An Application Report(s) is required to document qualification of a valv assembly for a specific nuclear plant application.
