ABSTRACT
STUDY OF SEVERE ACCIDENT MANAGEMENT STRATEGY FOR PWR TYPE REACTOR. Accident management is establishment of all the actions which aim to anticipate accidents and mitigate the consequences due to the accidents in nuclear power plants such as PWR type reactors. There are two categories of accidents, that are; the accidents in the DBA (design basis accident) category and the accidents in the beyond DBA category, namely severe accident. Accident management comprises the prevention measure to maintain the core cool ability and containment integrity for design basis accident events using safety-related and inside the design limits. There are two phases of severe accident management. One is the countermeasure to prevent severe damage to the reactor core that is called "phase-1 accident management". The other is the countermeasure to mitigate the consequences of severe accident that is called "phase-2 accident management", this countermeasure particularly to keep the containment vessel integrity in order to mitigate the material radioactive release to the environment. This paper describes a concept of some countermeasure according to the severe accident management such as to maintain core cooling, containment integrity and some support system to the safety function.
