FLUIDIC DEVICE FOR SAFETY INJECTION TANK OF REACTOR

摘要

PURPOSE: A device for controlling the amount of liquid injected into a safe injection tank of a nuclear reactor is provided to use all supplied safe injection liquid to cool a core and lengthen ejection time of safe injection liquid by increasing the pressure loss coefficient of an eddy flow. CONSTITUTION: A mixed space part comprises a closing plate(40), a partition plate(60), a plurality of eddy flow forming plates, and a lower plate(80). The closing plate is connected to a safe injection liquid supply pipe. The partition plate spreads safe injection liquid supplied from the safe injection liquid supply pipe to adjacent parts and discharges the safe injection liquid downward through a through hole.
