Emergency operating guidelines provide technical guidance for the development of plant specific emergency operating procedures. These guidelines provide the actions necessary for mitigation of plant events that necessitate a reactor trip and initiated in Mode 3 or 4.
We know that EOG is closely related to safety of plant through Fukushima accident. We are performing researches for enhancing the plant safety by upgrading EOG. Innovative nuclear plant is under development in Korea. Thus well-matched EOG must be developed in consideration of new passive safety equipment use. We are developing a new EOG for hybrid safety injection tanks and passive emergency core cooling systems.
