Knowledge and Experience Sharing Workshops

Equipment Qualification of Nuclear Power Plant Components Important to Safety

Read disclaimer

This workshop deals with the qualification of electrical, electronic, electromechanical and mechanical equipment for postulated service conditions (‘harsh’ accident environments, normal and abnormal ‘mild’ environments, and seismic conditions). Piping, structures and other passive NPP components are not within the scope of this report because their qualification (safety status) is achieved directly by design, construction, inspection and testing according to applicable codes.

In addition, after completion of the workshop each participant should be familiar with IAEA guidance on equipment that is documented in Safety Reports Series No. 3 “Equipment Qualification in Operational Nuclear Power Plants: Upgrading, Preserving and Reviewing”, IAEA, Vienna (1998).
