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, and particularly relates to a pulse 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 (the nuclear reactor heats liquid hydrogen to a high temperature gas state, and high-speed outward ejection produces large thrust) and magnetic fluid power generation technology, Form an open nuclear magnetic fluid power generation system. Its output power is high, stable power can reach more than 100MWe, instantaneous power can reach gigawatt level, nuclear reactor adopts NERVA type nuclear rocket reactor or UF4 gas core nuclear reactor. After 2000, the demand for deep space exploration led the United States, Russia, Japan and other countries to propose a...
