Abstract

The author reports the use of the Nordheim formula in the case of Zoe (a pile located in Chatillon), while considering the case bars in natural uranium (instead of UO{sub 2}), and while taking the effect of geometry on photo-neutron production into account. The Nordheim formula is calculated for two different experimental values of the constants of delayed neutrons. The author discusses the difference between the results obtained for reactivity with these new conditions and with the older ones. He reports the calculation of the geometrical factor.
