The Main Control Room(MCR) of Korean Next Generation Reactor(KNGR) has faced entirely new operation environment. The Computerized Procedure System(CPS) is completely different from existed Paper-based Procedure(PBP). The CPS which is improved by evaluation in this study is ready to be applied to the ergonomic foundations. In this study, we redesigned displays of the CPS as a Man-Machine Interface System(MMIS) to maximize human performance and to minimize human error and proposed an alternative display designs of the CPS applying principles related with MMIS.
