ABSTRACT:
In an accident involving the uncontrolled escape of coolant, a condensate film forms on the power station components. Due to deposited dirt it is conductive, and if the insulation has aged it can cause electrical function defects. That situation is simulated by spraying a test liquid, having a wetting power (surface tension) and a conductivity which correspond to the coolant condensate, onto the electrical power station components. The testing can be carried out on a routine basis at normal pressure and normal temperature during ongoing reactor operation.
