원자력발전소의 중대사고 상황 관리를 지원하기 위한 생태학적 정보디스플레이 설계를 위한 정보요건의 도출

Abstract

Objective: This study aims to identify and organize information requirements for designing ecological displays supporting responsive actions under severe accident situations of nuclear power plants (NPPs).BRBRBackground: One of the requisites for supporting human operators in handling severe accident situations in complex systems such NPPs is to design information displays that satisfy information needs of human operators. Ecological Interface Design (EID) has been regarded as a viable approach for developing user-centered information displays. This study follows the design process and principles of the EID framework.BRBRMethod: We firstly identified functional knowledge structure of a work domain related to severe accident situations of NPPs through work domain analysis (WDA) using abstraction hierarchy (AH). After validating the WDA model through expert review, we finally specified information requirements for ecological displays.BRBRResults: This study identified and organized information requirements for designing information displays that can be effectively used for supporting human operators in severe accident situations in NPPs.BRBRConclusion: A set of information requirements obtained from this study would be useful in designing information displays supporting human operators in coping with severe accident situations in NPPs.BRBRApplication: This study can contribute towards enhancing the safety of NPPs by providing a set of meaningful information requirements that should be offered to human operators in severe accident situations where their tasks could be very cognitively challenging.
