MEASUREMENTS OF Pu239:U235 FISSION RATIO USING FOILS AT TEMPERATURES UP TO 4OO°C

摘要

The paper describes the use of activation foils for the measurement of Pu239:U235 fission ratios in subcritical lattices at temperatures up to 390°C.nCounting techniques and the method of analysis of the results are described in detail and the results are compared with fission chamber measurements.
