HYBRID CONTROL ROD COMBINED WITH HEAT PIPE AND NEUTRON-ABSORBING MATERIALS AND, HEAT REMOVAL SYSTEM OF NUCLEAR REACTOR

摘要

The present invention relates to a heat pipe for removing the heat of a reactor core during an emergency situation. The technical aspect of the present invention relates to a heat pipe which quickly and easily removes the heat generated in a core when power supply is stopped in an emergency situation of the reactor. The heat pipe is a passive cooling device which has high heat transfer performance and does not require an additional energy source. The heat pipe has excellent usability due to various sizes and shapes of heat pipes. In particular, the heat of the heating unit (evaporator) can be effectively transmitted to a cooler (condenser) through the phase change of working fluid. A conventional problem of the degradation of an internal structure due to bubble generation can be significantly ameliorated. In addition, the pipe can function as a control rod for controlling the nuclear reaction of fuel by controlling a neutron.
