| description | In this work a generalized burn criterion for thermonuclear fusion reactors for space is derived. It considers not only the most important subsystems distinguishing terrestrial from astronautic magnetic confinement fusion technology but also features like a variable hot ion mode, a variable fuel ratio and a ratio coupling fusion product ions confinement time with energy confinement time. The modeling is based on a power density flux model. Solving the energy and particle balance equations for the triple product, an analytical expression for a more general burn criterion is obtained. The results for commonly studied reactant couples (D–T; D–
