SEPARATION REMOVAL APPARATUS AND SEPARATION REMOVAL METHOD OF TRITIUM WATER

摘要

PROBLEM TO BE SOLVED: To enable tritium water to efficiently be separated and removed from light water which contains the tritium water.;SOLUTION: A freezing tank 2 makes: crystals 9 of frozen tritium water to be precipitated in a laminar form by the progressive freeze-concentration method; simultaneously at least a part of the crystals to be removed by scraping with a scraper 10; contaminated water which contains removed crystals 9a of frozen tritium water to be fed to an aging tank 3 to grow crystals of frozen tritium water; contaminated water which contains grown crystals 9b of frozen tritium water to be separated into crystals of frozen tritium water and contaminated water with a solid-liquid separator 4; and the contaminated water to be returned to the freezing tank 2 via a circulation pump 5.;COPYRIGHT: (C)2015,JPO&INPIT
