HFE V and V Results of Computerized Procedure System for APR+

Since the CPS (computerized procedure system) has applied to SKN3 and 4 units at first, operators suggested many design change items and operating experience derived from user experience. Though the logic composition of CPS was very good to use, there were opinions that the esthetic design of CPS MMI display was insufficient. So many operators proposed an improvement of CPS MMI display such as the frame of display and the shape of button etc. In this paper, the major design changes and HFE V and V results of CPS for APR+ were introduced to increase the practical use of CPS. The design changes of CPS for APR+ were performed to improve the operator usability based on the proven APR1400 design. In addition to the design changes of CPS described above, the followings should be investigated closely for APR+ to get into the global nuclear industry.
