Understanding ageing and degradation of safety system equipment
containing power electronics is of great interest to nuclear power plants.
The ageing status might impact or be the reason for sudden failure when
components are hit by a transient.
This project addressed the ageing and robustness of nuclear power plant auxiliary power DC systems and UPS devices containing power electronic components. By increasing the understanding one can find better ways to monitor and predict when equipment should be replaced based on time and experienced abnormal stress.
