ABSTRACT

             A proposal discussed in this paper is method of increasing the safety of nuclear plant by using the potential energy of water. A reactor is built in the low place than a source of cooling water level. A water gate is installed between the source of cooling water and the place where reactor is built. A water gate becomes safety devices. In addition, this paper proposes the handling method of nuclear reactor which caused an accident or finished a duty. And this paper shows the dream for the next generation. It is a safe nuclear plant than now.
