Feasibility of Fluorination Treatment Method for Management of Wastes Generated from Fuel Debris Retrieval
The feasibility and effectiveness of fluorination treatment method for reasonable management of wastes generated from fuel debris retrieval at Fukushima-daiichi nuclear power station was investigated experimentally.The simulated fuel debris assuming the molten core-concrete interaction (MCCI) debris was prepared, and the fluorination behavior of each element in the simulated fuel debris was evaluated.The results indicated that 90 % of the uranium was volatilized by fluorination, and the waste after fluorination treatment can be partitioned into the nuclear fuel material, the radioactive waste, and the silica waste.
