AUTOMATIC BREAK FLOW STOPPAGE DEVICE AND NUCLEAR POWER PLANT HAVING THE SAME

摘要

Provided is an automatic break flow stoppage device includes a body of forming a flow path to allow a cooling material to pass, a connection pipe which is connected to the upper part of the body to allow the cooling material in the body to flow, and a driving part which reciprocates in the flow path to block the leakage of the cooling material and is lowered by a load and an applied pressure, moves from a first state of allowing the flow of the cooling material to a second state of sealing the upper part of the body according to the change of a pressure generated due to the breakage of the connection pipe.
