Title:
RADIOACTIVE MATTER TREATMENT SYSTEM
Document Type and Number:
Japanese Patent JP2015187552
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radioactive matter treatment system capable of facilitating reducing the tritium concentration of a part of treatment water to a concentration satisfying a discharge reference value while reducing the volume treatment water to be stored and treated.SOLUTION: The radioactive matter treatment system includes: a first treatment section 5 that separates discharged water C1 which contains tritium after heat exchange in a nuclear reactor 2 into concentrated water B1 and low concentration permeated water P by means of reverse osmosis; a second treatment section 6 that performs absorption treatment of a radioactive matter from the concentrated water B1 discharged from the first treatment section 5 and discharges absorption treatment water B2; a third treatment section 7 that separates the low concentration permeated water P discharged from the first treatment section 5 into high concentration treatment water T and low concentration treatment water W: and a circuit 10 that circulates the absorption treatment water B2 treated by the second treatment section 6 to the nuclear reactor 2.
