Problems solved by technology

The main problems of these methods are as follows: ①The construction cost is high, and a new heavy water tritium reactor or high-temperature gas-cooled reactor will cost about 5.5 billion US dollars; ②Environmental safety issues, using reactors to produce tritium not only has reactor safety issues, but also involves The safety issue of tritium; ③The issue of nuclear non-proliferation. Most tritium-producing reactors use weapon-grade highly enriched uranium as fuel. In order to reduce the risk of nuclear proliferation, some countries use low-enriched uranium as fuel for heavy water reactors to produce tritium. The result is Increased costs, decreased production capacity

Embodiment 1

[0089] use Figure 4 The described device contains 3mmol / l 6 LiD heavy water is the first fluid medium, and heavy water containing 1.8 mmol / L sodium lauryl sulfate is the second fluid medium for preparing tritium. The water level of the second fluid medium in the reaction assembly 600 is as high as image 3 The water level line A is shown, and the specific preparation process is as follows:

[0090] (1) Will contain 3mmol / l 6 The heavy water of LiD is provided with a high-pressure, high-speed heavy water jet by the plunger pump 550, and the pressure of the jet is in the range of 10-15 atmospheres.

[0091] (2) The heavy water jet enters the device through the inlet 510, and is processed by the cavitation disk 580 to generate microcavitations, forming a cavitation flow, and entering the mass transfer space of large volume. The partition divides the mass transfer space into the upper fluid medium area and In the lower ultrasonic generating area, the cavitation flow flows in the upper ...

Abstract

The invention discloses a method, a device and a system for preparing tritium. The method for preparing tritium comprises the following steps: a first fluid medium is compressed through a plunger pump to form a jet flow, wherein the first fluid medium contains <6>LiD with concentration of at least 2mmol / L; the jet flow is cavitated with a cavitation plate to form a cavity flow containing cavities; the cavity flow passes through a labyrinth channel, and mass transfer is performed on a liquid-vapor interface under the effect of an ultrasonic field to obtain a high-content cavity flow; and a nozzle is used to make the high-content cavity flow to hit the upper surface of a metal work piece in a second fluid medium at the speed of 60-100m / s, and the high-content cavity flow approaches the upper surface of the metal work piece to realize deuterium-deuterium thermonuclear fusion and obtain tritium and fast neutrons, wherein the second fluid medium contains deuterium, the fast neutrons slow down in the second fluid medium to obtain thermal neutrons, and the thermal neutrons reacts with <6>LiD to generate additional tritium. By using the method, deuterium-deuterium thermonuclear fusion is realized, and tritium can be safely and simply prepared with low cost.

Description

Technical field [0001] The present invention relates to the fields of tribology and nuclear physics, and in particular to methods, devices and systems for preparing tritium. Background technique [0002] The half-life of tritium is 12.3 years. There are only about 2 kilograms of natural tritium on the earth, of which 10 grams are stored in the atmosphere, 13 grams are stored in groundwater, and the rest is stored in seawater. Tritium is not only used for military purposes, but also widely used Civilian field. [0003] At present, the production of tritium mainly depends on the nuclear reaction of nuclear fission reactors, the method of irradiating Li through the neutrons produced by the reactor, or the method of bombarding Be target in a cyclotron to obtain tritium. The main problems of these methods are: ①The construction cost is expensive, and a new heavy aquatic tritium reactor or a high-temperature gas-cooled reactor needs about 5.5 billion US dollars; ②Environmental safety is...
