摘要:
An extrusion molding apparatus 10 includes: a container 13 that a container 13 into that a kneaded material 12 containing inorganic adsorbent 11 having radionuclides adsorbed thereon is thrown; a mold cavity 14 of a specified shape provided on a wall surface of the container 13; an extrusion unit 16 that is provided inside the container 13 to extrude the kneaded material 12 out of the container 13 through the mold cavity 14; and a hydrogen removal unit 17 that is provided in the container 13 to recombine hydrogen gas 23 generated inside the container 13 and to remove the hydrogen gas 23.
摘要:
A solidification method of radioactive waste is provided, including kneading a binder and an inorganic adsorbent to obtain a kneaded object, the in organic adsorbent included radionuclides; extruding the kneaded object to obtain an extruded material object; cutting the extruded material object to obtain at least one extruded material block; and firing the at least one extruded material block to solidify the at least one extruded material block.
摘要:
A method for manufacturing a solidified body of a radioactive waste includes a kneading step (S12 to S18) for kneading, together with a molding adjuvant, an inorganic adsorbent adsorbing radionuclides to generate a kneaded body, an adjusting step (S14 to S17) for adjusting a water content of the kneaded body to be within a predetermined range, a molding step (S19) for molding the kneaded body by extruding, a cutting step (S20) for cutting, at a specified interval, the kneaded body extruded in a bar shape, and a baking step (S22) for baking the cut kneaded body into a solidified body.
摘要:
Provided is a technique for solidifying radioactive waste, which enables stable final disposal of a large amount of radioactive waste with a simple process.A method for producing a solidified body of radioactive waste includes: a step (S11) of retrieving radioactive waste generated at a nuclear power plant or a nuclear related facility, a step (S12) of pressurizing radioactive nuclides contained in the radioactive waste along with an inorganic adsorbent and thereby forming a molded body; and a step (S13) of firing the molded body and thereby forming a solidified body.
