Riff Raff-a Program for Computation of Resonance Integrals in a Two-Region Cell

Neutron Resonance Theory for Nuclear Reactor Applications: Modern Theory and Practices.

“…Because of its safety implication, one fast reactor parameter of particular interest is the Doppler coefficient discussed earlier. The need for analyzing the Doppler effect measurements in the highly heterogeneous system provided the strong motivation for the development of the continuous energy approaches for treating the complex cells with many regions [63][64][65][66][67][68][69][70][71][72][73][74][75]. The presence of a large number of resonances and spatial regions lead to the more frequent use of the effective cross section concept in addition to the traditional resonance integral approach.…”

Monte Carlo analysis of reactivity coefficients in fast reactors general theory and applications

“…Particular emphasis has been placed upon eliminating certain approximations and assumptions that limit the accuracy and reliability of other current techniques. 41,56,60 The elimination of these approximations and assumptions, which was to make it possible to investigate the effect of fuel diameter on the Doppler coefficient,…”
