Abstract
Impact of component and module-level replacement on electromagnetic compatibility (EMC) qualification in nuclear power plants is studied in this paper. Recently component or module of instrument and control (I&C) devices is replace for many reason such as unavailability of the existing component and upgrading from analog to digital. Nevertheless, it is difficult to find testing practice and acceptance criteria for the situation but there is an impractical aspect to test the whole system as the initial EMC verification. Technical reports and industrial standards for the practical EMC qualification of component or module-level replacement are investigated. The prototype digital I&C cabinet in Korea nuclear power plant is analyzed to evaluate the EMC characteristic and especially the modeling and EM simulation of POSAFE-Q programmable logic controller with card type module configuration change is performed.
