Passive nuclear safety is a design approach for safety features, implemented in a , that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency (usually overheating resulting from a or loss of coolant flow). Such design features tend to rely on the engineering of components such that their predicted behavio.
