Encyclopedia > Nuclear reactor core

In a gaseous fission reactor the reaction takes place in a core which is bounded and created by magnetic field. The fuel is supplied and fission occurs in the gas phase. Gaseous fission reactors are a hypothetical type of nuclear reactor proposed for use in space travel. ... It has been suggested that Magnetic field density be merged into this article or section. ...

Gas-cooled nuclear reactor plant with a heat exchanger for removing afterheat - Patent 5265134 (1311 words)
During normal operation of the nuclear reactor plant, there is a flow of cold gas through the heat exchanger in the direction toward the reactor core and in the event of an emergency, there is a flow of hot gas in a direction out of the center of the core of the reactor.
It is accordingly an object of the invention to provide a gas-cooled nuclear reactor plant with a heat exchanger for removing afterheat, which overcomes the hereinafore- mentioned disadvantages of the heretofore-known devices of this general type and which provides an afterheat removal solely on the basis of natural draught.
The reactor core rests on a bottom reflector 4 which is penetrated by a discharge tube 5 for the spherical fuel elements.
Gaseous fission reactor - Wikipedia, the free encyclopedia (573 words)
A limitation for conventional nuclear fission reactors is that if the nuclear fuel temperature were to rise too high in temperature, the Nuclear reactor core would melt.
A potential benefit of the gaseous reactor core concept is that instead of relying on the traditional rankine or brayton conversion cycles, it may be possible to extract electricity magnetohydrodynamically, or with direct conversion of the charged particles.
The terrestrial version is designed for a vapor core inlet temperature of about 1500 K and exit temperature of 2500 K and a UF to helium ratio of around 20% to 60%.
