High Temperature Gas Heating by Fission Fragments Deposition

The consept of gaseous coolant direct healing in the reactor core by fission fragment deposition is considered. The temperatures as high as (3-5)*10³ K can be reached and total heat power of the single module be of order 10-20 MW. The prospects of using the latter in space propulsion systems as well as in combination with closed - circle MHD generator or by direct water thermodissociation are discussed.
