Integrated System For Converting Nuclear Energy Into Electrical, Rotational And Thermal Energy
Provided is an apparatus for generating electricity, mechanical energy, and/or process and district heat using a gas propellant chamber fueled with fissile material and enclosed in a sealed containment vessel which also contains an operating gas. The system allows for the operating gas to be compressed as it enters the nuclear fuel chamber where it is heated. As the operating gas exits the nuclear fuel chamber, the kinetic energy of the gas is converted to rotational energy by a variety of methods. The rotational energy is further converted to electricity, mechanical energy, and/or process and district heat. The operating gas circulates in the containment vessel and is cooled prior to re-entering the gas propellant chamber. The apparatus thereby provides a simpler and safer design that is both scalable and adaptable. The apparatus is easily and safely transportable and can be designed to be highly nuclear-proliferation-resistant.

- 1. An apparatus for generating electricity comprising:
a gas propellant chamber comprised of an annular body defining first and second ends, the first end of the annular body defining an inlet assembly that is configured to draw operating gas into the gas propellant chamber and the second end defining an exhaust assembly that is configured to expel operating gas from the gas propellant chamber, wherein the gas propellant chamber is disposed in a containment vessel, the containment vessel having an inner wall and an outer wall, the inner wall and outer wall of the containment vessel defining a circulation path therebetween through which the operating gas travels from the exhaust assembly to the inlet assembly, wherein the inner wall and the annular body of the gas propellant chamber further define a region therebetween, the region forming a bypass for a first portion of the operating gas to pass around the annular body; a nuclear fuel chamber positioned within the annular body of the gas propellant chamber between the first and second ends, the nuclear fuel chamber housing nuclear fuel elements and defining one or more interior chambers forming one or more elongate flow paths within the nuclear fuel chamber through which a second portion of the operating gas passes and heat is transferred from the nuclear fuel elements to the operating gas; a compressor positioned proximate to the first end of the gas propellant chamber, the compressor configured to compress the operating gas prior to entry into the nuclear fuel chamber; a conversion apparatus positioned proximate to the second end of the gas propellant chamber, the conversion apparatus configured to convert kinetic energy of the operating gas exiting the nuclear fuel chamber into rotational energy; and a drive shaft extending axially through the gas propellant chamber between the first and second ends, the drive shaft coupling the compressor to the conversion apparatus.
