METHOD AND SYSTEM FOR REMOVING RADIOACTIVE CESIUM

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of efficiently removing radioactive cesium by volatilization from incineration ash while suppressing an increase in energy consumption, in a radioactive cesium removing technique for removing radioactive cesium by volatilization from incineration ash by adding a cesium volatilization accelerator to the incineration ash and heating the incineration ash.SOLUTION: When executing addition processing for adding a cesium volatilization accelerator to incineration ash generated in association with incineration of waste and heat processing for heating the incineration ash to which the cesium volatilization accelerator has been added, a method for removing radioactive cesium executes crystallization processing for holding the incineration ash in a crystallization temperature range to crystallize an amorphous component before the addition processing of the cesium volatilization accelerator.SELECTED DRAWING: Figure 1
