Description

The experience from the last 40 years has shown that severe accidents can subject electrical and instrumentation and control (I C) equipment to environmental conditions exceeding the equipment s original design basis assumptions. Severe accident conditions can then cause rapid degradation or damage to various degrees up to complete failure of such equipment. This publication provides the technical basis to consider when assessing the capability of electrical and I C equipment to perform reliably during a severe accident. It provides examples of calculation tools to determine the environmental parameters as well as examples and methods that Member States can apply to assess equipment reliability.
