Nuclear Thermal Propulsion

Abstract: This chapter will cover the fundamentals of nuclear thermal propulsion systems, covering basic principles of operation and why nuclear is a superior option to chemical rockets for interplanetary travel. It will begin with a historical overview from early efforts in the early 1950s up to current interests, with respect to fuel types, core materials, and ongoing testing efforts. An overview will be provided of reactor types and design elements for reactor concepts or testing systems for nuclear thermal propulsio… Show more

“…Indeed, while Doppler feedback effects are strictly local, the multigroup condensation process uses the neutron spectrum to compute cross-sections which depends significantly on conditions elsewhere in the core [1]. A significant approximation in this work-which will have to be addressed in the future-is that the cross-sections can be tabulated by assuming fixed axial profiles for all state variables, as was done in [12].…”
