Filed: 1990-12-25
Abstract: PURPOSE:To dispose radioactive sludge of a relatively high level in a form, in which the sludge can be stably reserved for a long period, through a simple process and to reduce exposure of a worker to radiation by performing pretreatment and stabilizing treatment in the same container. CONSTITUTION:Sludge 2 having relatively high radiation concentration is transferred from a sludge storage tank 1 to a treating container 3. In this case, a solidifying agent 4, such as cement and glass powder, is added and agitated and mixed. Continuous dehydrating treatment is carried out in the same container 3 by an electric permeation method. After dehydrating treatment, in case of the agent 4 being cement, it is left standing as it is to form a cement cured substance. In case of the agent 4 being glass, after stabilizing treatment (process C) of water heat synthetic reaction is carried out by means of a heater 6 and a press 7, the glass powder forms an uniform solid substance 8. As noted above, since the number of treating containers and conveyance of sludge during the treatment can be eliminated, an amount of a generating radioactive contaminated material is reduced, and a risk of a worker being exposed to radiation can be reduced.
