The Physical Theory of Neutron Chain Reactors

MONTE CARLO CALCULATION OF THE TRANSLATIONAL RELAXATION OF SUPERTHERMAL H ATOMS IN THERMAL H2GAS

“…A finite amplitude for P (u) could be obtained by selecting the initial energy from a Gaussian, as in the work by Prisant et al (1978). Following the custom for P (u) plots in nuclear applications (Weinberg & Wigner 1958) this contribution has not been represented.…”

“…This problem can be tackled by using a continuum slowing down approximation similar to the Fermi theory (Robson 2006), but a much better method is to apply a rigorous thermalization theory developed for the case of neutron kinetics in gaseous moderators (Weinberg & Wigner 1958).…”

Control and Stability Analysis of Spatially Dependent Nuclear Reactor Systems.

“…For breeder or converter systems, the buildup of Pu239 from the Equation (9) indicates that the rate of change of plutonium concentration is equal to the rate of plutonium production from neptunium decay, less the rate ef loss of plutonium due to absorption and fission.…”

Design study of a fission-electric cell reactor

“…Furthermore it is assumed that the charge on the light fragment varies as the square root of the velocity, while that of the heavy fragment varies as the velocity itself. Although there is little information concerning the ranges in solids for each fragment, on the basis of measurements reported in gases (Ref,5) it will be assumed that the ranges are proportional to the initial energy. In these equations the voltage P is in units of Eo/e, where Eo is initial fragment energy and e is initial fragment charge.…”
