RADIOACTIVE WASTE LIQUID DISPOSAL SYSTEM

摘要

PROBLEM TO BE SOLVED: To shorten the disposal time and improve the reliability of filtrate quality by monitoring the state of a cake layer formed within a filter. SOLUTION: A pump 2 and the filter 3 are connected to a radioactive waste liquid collecting tank 1 through piping. A turbidmeter 8 is set in the filtrate discharging pipe 18 of the filter 3. The outlet side of the turbidmeter 8 is connected to a sump tank 4 through a sump tank inlet valve 21. The sump tank inlet valve 21 is remotely opened and closed by a measurement control device 11. One side of a return pipe 5 branched from the sump tank inlet valve 21 is connected to the outlet side of the turbidmeter 8, and the other is connected to the collecting tank 1. A collecting tank return valve 20 remotely opened and closed by the measurement control device 11 is set in the return pipe 5. A cake discharge valve 19 is connected to the cake discharge side of the filter 3, and a metal drum 6 is connected to the downstream side from the cake discharge valve 19. A powdery activated charcoal feeder 7 is connected to the collecting tank 1.
