NASA’s Marshall Space Flight Center hosts nuclear propulsion cold-flow tests
Nuclear rocket propulsion has been investigated for decades, and NASA and the Atomic Energy Commission carried out significant testing in the 1960s as part of the Nuclear Engine for Rocket Vehicle Application program. NERVA chased the potential of the efficiency and energy density of nuclear thermal propulsion to extend our reach to new space frontiers before the program ended in 1973.

A possible method for steady-state sustainment of a tokamak through coaxial helicity injection is presented. To keep the toroidal flux constant, two insulators are used, one that injects and one that absorbs toroidal flux. The scheme is made attractive by incorporating the toroidal field of the tokamak in the source to raise its impedance.
