  The present invention relates to a method and apparatus for separating and recovering beryllium resources from beryllium containing impurities, and a recovered high-purity metal beryllium.

  Beryllium is a material that plays a unique and valuable role as a neutron reflector in a nuclear fission reactor that utilizes the uranium fission reaction and as a neutron multiplier in a fusion reactor as a future energy source. However, beryllium resources are scarce, and used and activated beryllium (impurity-containing metal beryllium) must be reused to secure resources.

In FIG. 1, impurity-containing beryllium contains volatile and nonvolatile impurities, volatile radioactive tritium, nonvolatile radioactive cobalt, and the like. A method for separating and recovering beryllium resources from impurity-containing beryllium metal,
Beryllium containing volatile and non-volatile impurities, volatile radioactive tritium and non-volatile radioactive cobalt is melted at high temperature and then solidified to form a large number of small-sized beryllium grains. First step to remove volatile impurities and volatile radioactive tritium (Beryllium fine particle formation, radioactive tritium removal step, ie, used Be melting & tritium removal step)
Halogenation reaction with chlorine gas, bromine gas or iodine gas produces beryllium halide of beryllium chloride, beryllium bromide and beryllium bromide, in which non-volatile impurities and radioactive cobalt are separated, Second step of mixing chemically active hydrogen gas into the generated beryllium halide (production of beryllium halide, removal of radioactive cobalt, hydrogen gas mixing step, ie halogenation step)
The third step of converting beryllium halide into pyrolysis gas of beryllium metal and hydrogen chloride, hydrogen bromide or hydrogen iodide by pyrolysis in the presence of hydrogen gas (beryllium metal and decomposition gas generation process by pyrolysis, ie metal Beryllium formation process)
Fourth step of separating metal beryllium and cracked gas from fluid gas containing metal beryllium and cracked gas (metal beryllium, cracked gas, tritium halide separating step, ie, metal beryllium and residual halogen element recovery step)
It is comprised including.

  Volatile impurities including volatile tritium are trapped by melting of spent beryllium which is an impurity-containing beryllium in the first step, and molten metal beryllium is dropped and solidified by a large number of fine beryllium, that is, beryllium fine grains (for example, diameter) 1 mm spherical beryllium). In this embodiment, the dropping method is adopted for miniaturization, but other miniaturization methods may be adopted. By miniaturizing, the surface area can be increased, the reaction efficiency can be increased, and halogenation described later is facilitated.

  In this process, spent beryllium is heated to 1300 ° C. or higher (preferably 1300 to 1600 ° C.) in an inert gas or vacuum, melted and solidified to a small size, and volatile substances such as tritium gas released at that time Is removed by flowing an inert gas such as argon gas or helium gas, or removed by evacuation to separate beryllium fine particles from volatile substances.

  In the second step, beryllium microparticles are reacted with a halogen element such as chlorine gas, bromine gas, or iodine gas at 500 ° C. or higher (preferably 500 to 650 ° C.) to convert (generate) volatile halogen beryllium.

The halogen compound of beryllium is produced by the reaction of halogen gas as follows.
Be + Cl ₂ → BeCl ₂
Be + Br ₂ → BeBr ₂
Be + I ₂ → BeI ₂

Beryllium halogen compounds are also formed by the following reactions and other reactions.
BeO + Cl ₂ + C → BeCl ₂ + CO
BeO + Br ₂ + C → BeBr ₂ + CO
At this time, non-volatile radioactive cobalt and the like are separated and removed.

  In this way, beryllium halide which is chlorinated beryllium, bromide bromide or beryllium iodide from which radioactive cobalt has been separated and removed is produced. These berylliums may be single or mixed.

  The generated beryllium halide is discharge-excited and mixed with chemically active hydrogen gas, and inert gas such as argon gas or helium gas is mixed as the carry gas, and the beryllium halide is kept at a temperature of 500 ° C. or more and transferred. To do.

  In the third step, volatile beryllium halide is decomposed at a high temperature by the action of active hydrogen gas at a high temperature part of 1200 ° C. or lower, preferably 800 to 1000 ° C. By this decomposition, high-purity metal beryllium is produced as a nonvolatile component. In addition, tritium halide, which is tritium chloride, tritium bromide, tritium iodide, is generated by reacting tritium remaining in the flowing gas with a halogen element (chlorine gas, bromine gas, iodine gas) generated by decomposition. Some of the remaining halogen elements (chlorine gas, bromine gas, iodine gas) are hydrogenated to form hydrides.

This step is a hydrogen reduction method in which BeCl ₂ , BeBr ₂ , and BeI ₂ are reduced with active hydrogen H (radical), and Cl ₂ , Br ₂ , and I ₂ can be removed as HCl, HBr, and HI. It is.
BeCl ₂ + 2H (radical) → Be + 2HCl
BeBr ₂ + 2H (radical) → Be + 2HBr
BeI ₂ + 2H (radical) → Be + 2HI
For example, dehalogenation reaction by iodine gas insertion method BeI ₂ + H ₂ → Be + 2HI
It is estimated that a high temperature of about 1000 to 1200 ° C. is necessary, but it was found that if the heater surface area is increased, a high metal beryllium recovery efficiency can be expected even at a lower temperature of about 800 ° C. .

  In the fourth step, the metal beryllium is separated and recovered from the fluid gas containing the metal beryllium and cracked gas produced in the third step and is recycled. At this time, chlorine or hydrogen chloride gas, bromine or odor in the gaseous state. Hydrogen fluoride gas, or iodine or hydrogen iodide gas, and gaseous tritium chloride, tritium bromide, or tritium halide of tritium iodide (or a mixture thereof) are trapped and separated simultaneously.

  In the case of bromine or iodine, it is cooled and recovered at 100 ° C. or lower, separated from gaseous tritium halide, and reused as a halogenating agent in the second step.

  By using the above-described steps, the produced beryllium halide can be thermally decomposed at a temperature of 1000 ° C. or less, and can be regenerated as a high-purity metal beryllium that hardly contains impurities, radioactive tritium, radioactive cobalt, and the like.

  The high-purity metal beryllium thus regenerated has a nonvolatile impurity of 10 ppm or less, a volatile radioactive tritium of 0.1 Bg or less, and a radioactive cobalt of 1 Bg or less.
