Tambovtsev, V. Dulin] An experimental investigation of the Doppler effect of reactivity in 238U and Pu on several fast critical assemblies BFS and KBR by measurement of the coefficients of reactivity of their cold and hot samples is described. The method used for computational analysis, making it possible to compare the results of measurements and calculations, employing the resonance self-screening factors (and their Doppler increments) of the BNAD system of group constants, is presented. This approach made it possible to take account of the Doppler increments near unresolved resonances. For 238U, the results of the measurements are compared with calculations. 2 figures, 2 tables, 7 references. Plenum Publishing Corporation, 2000 Tambovtsev S. A. I.
