AI Technical Summary

Technical Problem

Existing FRC devices have problems such as extremely high ignition temperature requirements for deuterium-deuterium reaction, lack of effective recovery and recycling of fusion products tritium and helium-3, single-pulse 'open-loop' operation mode, lack of a scheme for converting pulsed fusion power to steady-state power frequency AC grid connection, independent arrangement of DEC induction coil and magnetic confinement coil, and lack of inter-pulse dual-component selective recovery mechanism.

Method used

The design employs a linear vacuum chamber and a magnetic mirror coil group. Through single-stage fast compression and time-sequential multiplexing of the magnetic mirror coil group, the deuterium-deuterium fusion reactor achieves magnetic confinement recovery of tritium and helium-3. Combined with a zoned vacuum pumping system and a direct energy conversion induction coil, it forms a quasi-pulse self-sustaining operation, realizing the conversion from pulsed fusion power to steady-state power frequency AC.

Benefits of technology

The ignition threshold was lowered, enabling the recovery of tritium and helium-3 in a two-component magnetic confinement system. This improved the average power density, overcame the technical obstacles of pulsed power grid connection, simplified the device structure, and enhanced plasma stability and space utilization.

Abstract

The invention discloses a quasi-pulse FRC deuterium-deuterium fusion reaction device and a nuclear fuel self-sustaining cycle steady-state power generation method thereof. The device comprises a linear vacuum chamber, an FRC plasma forming area, a collision fusion area, a conical transition section, a forming coil, a fast compression coil, a magnetic mirror coil assembly, a deuterium and tritium feeding system, a partitioned vacuum pumping system and a pulse power supply control system. The magnetic mirror coil assembly is arranged at the position, close to the collision fusion area, of the conical transition section, four function modes of compression assistance, magnetic mirror reflection, magnetic bottle constraint and recovery attenuation are sequentially executed in a single pulse period, and the magnetic mirror coil assembly is reused as a direct energy conversion induction coil in the recovery attenuation mode. The operation mode adopts trace tritium to catalyze and ignite deuterium-deuterium fusion, tritium and helium-3 are constrained to participate in a secondary reaction through magnetic mirror constraint, bi-component selective recovery is realized by utilizing the chemical adsorption difference of tritium and the low-temperature condensation difference of helium-3 between pulses, quasi-pulse self-sustaining operation is formed, and the secondary reaction is realized. And the tritium and helium-3 are converted into steady-state electric power through a rectification-energy storage-inversion system for grid connection, so that cyclic utilization in the tritium and helium-3 device is realized.
