Problems solved by technology

[0003] Conventional nuclear reactors cannot cooperate with magnetic fluid generators to realize the function of pulse power supply, and cannot continuously output high-power electric pulses; existing pulsed nuclear reactors have low energy storage density, large volume and heavy quality; the service life of the core is limited and cannot be recovered quickly In addition, the control rods of existing nuclear reactors are usually controlled by an external power source to achieve the active shutdown function of the reactor, which cannot guarantee criticality safety and has a high risk of accidents

Abstract

The invention discloses a pulse nuclear reactor suitable for an MHD generator and a control method of the pulse nuclear reactor. The pulse nuclear reactor is combined with the MHD generator, so that fission energy is converted into electric energy rapidly and high-power pulse current is output directly; active and passive reactor stop are of non-active design, a critical safety characteristic is realized, and the risk of accidents is reduced; and it is ensured that the whole MHD generator and the pulse nuclear reactor run safely in high efficiency, the pulse nuclear reactor is more suitable for the MHD generator, high-temperature high-stress gas working medium is provided for the nuclear reactor, and the MHD generator can output high-power electric pulses.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactors, in particular to a pulsed nuclear reactor suitable for a magnetic fluid generator and a control method thereof. Background technique [0002] The open nuclear magnetic fluid power generation system / space nuclear power supply is based on the nuclear rocket technology developed by the United States and the Soviet Union in the 1960s (heating liquid hydrogen to a high-temperature gas state through a nuclear reactor, and ejecting it at a high speed to generate large thrust) and magnetic fluid power generation technology, Form an open nuclear magnetic fluid power generation system. Its output electric power is high, the stable power can reach more than 100MWe, and the instantaneous power can reach the order of gigawatts. The nuclear reactor adopts NERVA nuclear rocket reactor or UF4 gas core nuclear reactor. After 2000, the demand for deep space exploration led the United States, Russia, Japa...
