Feasibility of Fluorination Treatment Method for Management of Wastes Generated from Fuel Debris Retrieval

Year: 2025

Type: article

Abstract: 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.
