ABSTRACT:
A reactor comprising a reacting vessel31that contains a fluid including high temperature and high pressure water under target reaction temperature and reaction pressure condition and performs a reaction treatment to a reactant by the fluid, a first pipe25connected to the reacting vessel31to supply the reactant to the reacting vessel31, and a first partition means50for partitioning between first pipe25and the reacting vessel31so as to prevent a leakage of any one of the fluid, the reactant, and a reaction product from the reacting vessel31side to the first pipe25side. The first partition means50is comprised of for example a valve51, a shaft52, a weight53, a supporting member54, and a pipe55, and normally, due to the weight53, the valve51closes an opening of a bottom end of the pipe55. That is, it isolates the pipe55and the inside of the reacting vessel31. At this time, although the valve51does not completely seal up the inside of the reacting vessel31, it has the ability to prevent a large amount of hot water HW in the reacting vessel31from leaking into the pipe25due to a convection current thereof.
