[en] Electron energy distribution functions have been calculated in a ²³⁵U-plasma at 1 atmosphere for various plasma temperatures (5000 to 8000⁰K) and neutron fluxes (2 x 10¹² to 2 x 10¹⁶ neutrons/(cm²-sec)). Two sources of energetic electrons are included; namely fission-fragment and electron-impact ionization, resulting in a high-energy tail superimposed on the thermalized electron distribution. Consequential derivations from equilibrium collision rates are of interest relative to direct pumping of lasers and radiation emission. Results suggest that non-equilibrium excitation can best be achieved with an additive gas such as helium or in lower temperature plasmas requiring UF₆. An approximate analytic model, based on continuous electron slowing, has been used for survey calculations. Where more accuracy is required, a Monte Carlo technique is used which combines an analytic representation of Coulombic collisions with a random-walk treatment of inelastic collisions
