Approach for Risk Informed Circuit Analysis in Fire Hazard Analysis

In the fire hazard analysis for nuclear power plant, post-fire safe shutdown analysis is essential part to ensure that radioactive releases to the environment in the event of a fire will be minimized. Electrical circuit analysis for both safe shutdown circuit and associated circuits should be performed in safe shutdown analysis. The associated circuit is as important as safe shutdown circuit in safe shutdown analysis. An approach for risk informed circuit analysis is described in this paper
