Human Factors Engineering (HFE) program is applied from the early stage of the design process for Nuclear Power Plant (NPP) in Korea. A Task Analysis (TA) is an important part of the HFE program for the Main Control Room(MCR) design. Various nuclear regulatory documents require that the information and control requirements should be identified and evaluated before implementing the MCR design in order to support safe operation of NPP. These documents state that TA can be the basis for determining information and control requirements. Compared with TA for Optimized Pressurized Reactor 1000(OPR1000), a new methodology and wider scope were developed for TA of OPR1000+. During TA of OPR1000+, the requirements of information, decision making, task support and work load analysis which are required by NUREG-0711 were evaluated by the task decomposition method through Emergency Operation Procedure(EOP) walkthroughs. Furthermore, the review of MCR design including alarm window arrangement, alarm sound setting, new component evaluation and review of alarm display and Safety Parameter Display and Evaluation System(SPADES) display through screen simulation were performed to improve the operability. This paper explains TA methodology for OPR1000+ and their result to ensure that OPR1000+ design meets the requirement of accepted HFE principle.
