Abstract

Integral values of the capture-to-fission cross-section ratio for ²³⁹Pu and ²³³U have been measured in a soft spectrum fast reactor critical assembly using mass spectrometric techniques to determine the capture rate. Values of 0.363 ± 0.024 and 0.10 ± 0.04 were obtained for ²³⁹Pu and ²³³U, respectively. The value of 0.363 ± 0.024 is in good agreement with the value calculated using the revised Gwin differential cross-section data for ²³⁹Pu. The value for ²³³U is within experimental error in agreement with the value calculated using ENDF/B data.
