Fission fragment reactor
WebNov 21, 2024 · a fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40-45% attainable by efficient turbine-driven thermal reactors. WebJun 18, 2016 · The upper limit on reactor power is determined by two factors: effectiveness of fission fragment heating and dust cooling. Dust cooling requirements also put …

WebFeb 13, 2024 · nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. The process may take place spontaneously in … WebCreation of the fission fragments is followed almost instantaneously by emission of a number of neutrons (typically 2 or 3, average 2.45), which enable the chain reaction to …

WebWe analyze reactions of several types that are naively below threshold but can proceed because of the release of binding energy from nuclear fission and occasionally the formation of Coulombic bound states. These react…
WebJun 18, 2016 · The upper limit on reactor power is determined by two factors: effectiveness of fission fragment heating and dust cooling. Dust cooling requirements also put constraints on the hydrogen density. Similar to how the fission-fragment rocket produces thrust, a fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40-45% attainable by efficient turbine-driven thermal reactors. The fission fragment ion beam would be passed through a magnetohydrodynamic generator to pr…
WebAntimatter-catalyzed nuclear pulse propulsion (also antiproton-catalyzed nuclear pulse propulsion) is a variation of nuclear pulse propulsion based upon the injection of antimatter into a mass of nuclear fuel to initiate a nuclear chain reaction for propulsion when the fuel does not normally have a critical mass.. Technically, the process is not a '"catalyzed'" …
WebEnergy Content of Nuclear Fuels. To understand the fission reaction, and its difference from fusion, consider the simplistic but instructive analogy with the movement of marbles on a roller coaster (Figure 13-2).
