Radioactive waste processing device

Purpose: To greatly reduce operator's burden, issue an alarm before the liquid level reaches a dangerous height thereby enabling to take rapid countermeasures. Constitution: The generation amount of liquid wastes accumulated in a sampling tank per unit time is calculated and the liquid level in a plurality of collecting tanks during receiving of liquid wastes is detected. Based on the generation amount of the liquid wastes and the height of the liquid level, a forecasting time that the liquid level of the collecting tank reaches a predetermined level is calculated. Then, an alarm signal is issue upon judging that the forecasting time goes less than a predetermined value and liquid wastes generation amount, forecasting time and alarm are displayed. Since the information for making the operation planning can appropriately be displayed, operator's burden can be moderated. (Takahashi, M.)
