ABSTRACT
Thus, the MMIS environment of the advanced MCR developed to improve the convenience of operation demands the operators to conduct more tasks on security of the exactness and convenience. Accordingly, though the work of operators has been changed a great deal, due to a lack of appropriate guidelines on the role allocation or communication method of operators, the problem of an unbalanced workload for each operator has been raised. Thus, it is necessary to enhance the operation capability by developing the guidelines on the role definition and communication of operators in an advanced MCR of NPPs. In order to resolve this problem, however, a method of measuring the workload according to the work execution of the operators is necessary, but the applicable method is not available at this time. In other words, due to the operational activities of operators characterized by the digital MMI environment of the advanced MCR, it is necessary to develop a framework
1 INTRODUCTION
In a conventional Main Control Room (MCR) of a nuclear power plant, to operate the system facilities, the operators of each system operate various devices of the power plants by actuating the control switches on the board classified into each section. In an advanced main control room, however, the system operation is possible since the power plant facilities are controlled using the soft control embodied into the computerized procedures and distributed computers completely equipped with digital functions. Thus, for the operation of power plant facilities, while the operators of a conventional MCR can complete the work with the primary operation of the facilities, the operators under the environment of an advanced MCR need to additionally conduct such secondary operations as a GUI screen operation, which is not observed in a conventional MCR.
