국내 원자력발전은 전체 전력공급의 40%이상을 차지하고 있으면서도 그 특성상 기저부하용으로만 사용되고 있다. 그러나 전기에너지의 효율적인 이용과 다양한 전력수요에 능동적으로 대처할 수 있도록 원전의 부하추종운전 능력이 더욱 중요하게 인식되고 있는 상황이다. G7과제의 하나인 차세대원자로(Korean Next Generation Reactor, KNGR)는 기본적인 요건으로 부하추종운전 능력을 갖도록 개발되고 있다. 여기에서는 기존에 개발된 부하추종운전 제어논리를 변경된 부하추종운전 기본요건에 맞도록 하고, 구동 제어군 특성의 극대화 및 온도불감대 출력분포 제어논리 등을 개선시킴으로써 주기초 및 주기중 뿐만아니라 90% 주기말에서도 ASI(Axial Shape Index)가 만족스럽게 제어됨을 확인하였다.

Leak-before-break(LBB) approach has been shown to be both cost and risk effective by reducing maintenance cost and occupational exposure when applied to high energy piping in nuclear power plants. For Korean Next Generation Reactor(KNGR) development, LBB is considered for the Main Steam Line(MSL) piping inside containment. Unlike the reactor coolant piping leakages which can be detected by particulate and gaseous radiation monitoring, main steam line leak detection systems must be based on principles that do not involve radioactivity. Ceramics are widely used as humidity sensor materials which can be further developed for nuclear applications. In this paper, we describe the progress in the development of ceramic humidity sensors for use with the main steam lines of KNGR.

Most of Instrumentation and control system in Nuclear Power Plant using analog equipment has a limitations in system designing and operation. So the network based PLC application to Nuclear Power Plant has been studied so far. This paper defines the configuration and method with Prototype which are to be applied to NPCS(NSSS Process Control System) of KNGR (Korea Next Generation Reactor). It is expected that Test result of NPCS Pototype will satisfy the essential requirements in designing KNGR.

Situation awareness is defined as a person's perception of the elements of the environment within a volume of time and space, the comprehension of their meaning and the projection of their status in the near future. Situation awareness is important in attempting to evaluate human behavior in operating complex systems such as aircraft, air traffic control, and nuclear power plant systems. From the literatures this study reviews the relationship between situation awareness and numerous individual, system and environmental factors, and also reviews the methodologies for the empirical measurement of situation awareness applicable to Korea Next Generation Reactor (KNGR) design project. Attention, working memory, workload, stress, system complexity, and automation are presented as critical factors limiting operator's situation awareness. Mental models and goal-directed behavior are hypothesized as important mechanisms overcoming these limits. This study summarized hypothesized guidelines for interface design to improve situation awareness of reactor operators. Some of the guidelines should be tested in the KNGR evaluation experiments in the future.
