Problems solved by technology

However, if traditional active metals (Mg, Zr, etc.) or alloy fillers (ZrNi, ZrMnFe, etc.) are used, solid tritium-containing waste will be formed after the bed body fails, which will increase the burden of subsequent treatment; therefore, it is necessary to optimize the design of this method, and The overall design of the tritium recovery scheme in tritiated water can not only realize the efficient recovery of tritium, but also avoid the generation of solid waste

Abstract

The invention discloses a device of recycling tritium from tritiated water, which includes, in a successively connected manner through pipelines, a gas circulating pump, a buffer tank filled with an inert carrier gas, a tritiated water storage tank filled with the tritiated water, a first water decomposing bed filled with iron powder, a first adsorption bed filled with a 5A molecular sieve, and a first hydrogen storage bed filled with a zirconium-series hydrogen-storing alloy. The first hydrogen storage bed is also back-connected to the gas circulating pump. The device is compact in structure, is low in cost, is convenient to use, can be used for recycling the tritium from tritiated water continuously without generation of solid waste, and has excellent practical and popularizing values.

Description

technical field [0001] The invention relates to a device for recovering tritium from tritiated water and a realization method thereof. Background technique [0002] The tritium process laboratory will produce tritiated water (HTO) with different activities in the normal operation state or the tritium leakage emergency treatment state. Tritium in tritiated water cannot be used directly and must be converted into elemental tritium (HT) before it can be reused as nuclear fuel. Moreover, tritiated water is more easily absorbed by human organs than elemental tritium, which will lead to a greater radiation dose, and its dose coefficient is 25,000 times that of elemental tritium. Therefore, considering both resource utilization and environmental safety, it is necessary to convert tritiated water into single-state tritium to realize the recovery of tritium. [0003] At present, there are mainly the following methods for recovering tritium from tritiated water: electrolysis, isotop...
