REACTOR VESSEL FOR MINIMIZING ECC BYPASS

摘要

PURPOSE: A reactor vessel with an ECC(emergency core cooling) bypass reduction function is provided to prevent an LOCA(Loss-Of-Coolant Accident) due to the separation of an installation structure by removing an additional installation structure. CONSTITUTION: A reactor vessel(100) has a preset thickness. A nozzle part(110) is installed in the reactor vessel and supplies ECC water into the reactor vessel. A flow path(111) is vertically engraved in an inner wall(101) of the reactor vessel. A transverse section of the flow path is formed with a curved surface.
