Problems solved by technology

As a magnetic confinement method, the tokamak device still has complex structure, high cost, harsh working conditions, and it is difficult to implement steady-state operation and continuous operation of the reactor.
The laser inertial confinement method also has many difficulties to overcome: it is difficult for current lasers to make the plasma reach a high temperature and high density state, and it is also difficult to achieve continuous operation of the reaction
It is not yet possible to determine which way can truly realize commercial operation

Embodiment 1

[0036] Embodiment 1: In the present embodiment, the steps of realizing the acoustic nuclear fusion reaction method are as follows:

[0037] (1) The appropriately moderated 2.45 MeV neutron n emitted by the high-voltage multiplier, or the appropriately moderated neutron n of the isotope neutron source, or the thermal neutron n provided by the zero-power micro-nuclear reactor, the neutral neutron n Substances are used to irradiate the nuclear reaction liquid; the nuclear reaction liquid is composed of deuterium, tritium and tritium-containing lithium compound nuclear reaction substances;

[0038] (2) At the same time, apply high-intensity pulsed ultrasound to the nuclear reaction liquid, and its sound pressure is greater than 15 atmospheres. Under the action of ultrasound, deuterium-deuterium and deuterium-tritium reactions occur in the nuclear reaction liquid, thereby emitting 2.45 MeV or 14.1 MeV fast neutron n'

test Embodiment 2

[0073] The 2.45MeV neutrons provided by the high-voltage doubler are moderated by the water body with a thickness of 20cm, and the moderated neutrons irradiate the nuclear reaction liquid in the cylindrical reaction chamber (temperature ≤ 0°C). The nuclear reaction liquid is pre-placed in a vacuum box at 0-5°C for 30 minutes to reduce the dissolved gas content in the liquid. An ultrasonic transducer is placed coaxially with the reaction chamber, and ultrasonic pulses are applied during neutron irradiation, and the pulse mode is 1s on and off for 1s. The BF3 long counter tube measures the neutron pulse amplitude spectrum (effect spectrum) at the same time, and the measurement time is 959s. The liquid in the reaction chamber is irradiated with moderated neutrons, the ultrasonic pulse is canceled, and the BF3 long counter tube measures the neutron pulse amplitude spectrum (non-effect spectrum) at the same time, and the measurement time is 959s.

Abstract

The invention relates to a method and a device thereof for initiating deuterium-deuterium (D-D) and deuterium-tritium (D-T) thermonuclear fusion under an acoustic cavitation extreme physical condition by using energetic particles generated from low-energy neutrons nuclear reaction, and belongs to the technical field of controlled thermonuclear fusion. Based on the study of nuclear reaction in an acoustic cavitation field, the invention provides a method for realizing nuclear fusion reaction by using an acoustic cavitation effect, and provides a device for realizing nuclear fusion reaction by using the acoustic cavitation effect and a nuclear measurement device. The method comprises the steps of irradiating a nuclear reaction solution with neutrons emitted from a Cockcroft-Walton accelerator and subjected to a proper slowdown, wherein the nuclear reaction solution comprises nuclear reaction substances including deuterium, tritium, deuterium / tritium-containing compounds; and at the same time applying pulse ultrasonic sound with high sound intensity to the nuclear reaction solution, and allow deuterium-deuterium reaction and deuterium-tritium reaction in the nuclear reaction solution under the action of ultrasonic, so as to emit 2.45MeV or 14.1MeV fast neutrons.

Description

technical field [0001] The invention relates to a method and a device for deuterium-deuterium (D-D) and deuterium-tritium (D-T) thermonuclear fusion induced by energetic particles produced by low-energy neutron nuclear reactions under extreme physical conditions of acoustic cavitation. The invention belongs to the technical field of controlled thermonuclear fusion. Background technique [0002] Due to the limited resources of coal, oil and uranium, human beings will eventually face the problem of resource depletion. The gas emitted by fossil fuels such as coal and petroleum will cause serious environmental pollution. The radioactive waste produced by nuclear power plants that release energy through nuclear fission will cause potential harm to the earth due to its long half-life and high radioactive intensity. Another form of nuclear energy release is nuclear fusion. Fusion release energy is 3-4 times larger than fission release energy, and rarely produces radioactive subst...
