Radioactive liquid waste processing facility

In the present invention, an existent batch process is conducted from processing to recovery continuously in a radioactive liquid waste processing facility. After the start of the processing, processed water is returned to a liquid reservoir for a predetermined period of time and items for water quality control of the processed water is confirmed during this period. Then, water is recovered to a condensate storage vessel, and when the aimed values for the items of the water quality control of the processed water are not attained during the recovery, the processed water is returned to the liquid reservoir vessel. The switching is conducted based on the results of periodical and continuous diagnosis for the water quality of the processed water flowing in downstream pipelines of a liquid waste processing device by an automatic water quality analyzing device. With such procedures, a series of operation from the processing to the recovery of liquid wastes collected while mixing floor drains and low electroconductive liquid wastes are automated and conducted continuously without temporary storage thereby enabling to provide margin in view of time and save the amount of facilities.
