PRESSURIZATION LIGHT WATER STYLE ATOMIC REACTOR OUTER WALL CRITICAL LINE INSIDE PREVENTION SYSTEM

摘要

PURPOSE: By forming the radiating unit having a plurality of cooling fins on the outer circumference of the pressure vessel of the nuclear reactor the exterior wall critical heat flux preventing apparatus for the pressurized light water reactor is rapidly processing the radiant heat process in the pressure vessel outer circumference corresponding to the metal layer. CONSTITUTION: A radiating unit(110) is formed into the ring fixed to the outer circumference of the pressure vessel(12). A plurality of cooling fins is regularly formed in the outer circumference of the radiating unit into the columnar direction. The radiating unit rapidly emits the heat heat-released from the metal layer D". The storage comprises the alumina melt of the nano particle saved in the space part(13) formed between the pressure vessel and out of furnace cooling gad.
