WebAs a contribution in this direction, the initiating events (IEs) of the most critical accident sequences in the EU DEMO magnet system (with special reference to the toroidal field magnets) are identified here, adopting first a functional analysis and then a failure mode, effects, and criticality analysis. WebThe Postulated Initiating Event (PIE) is the point in the fault sequence at which normal operation and planned control of the safety function is lost. If nothing was done to rectify the situation the fault sequence would escalate, leading to radiation exposure of individuals.

WebPurpose of defining the initiating events An IE is a postulated event that could occur in a nuclear power plant. It is an occurrence that creates a disturbance in a plant and has the potential to lead to core damage, depending on the successful operation or failure of the various mitigating systems in the plant. rugby league world cup 2021 ticket prices
