Abstract : A semitheoretical determination of the percentage change in reactivity of the water boiler per gram of 25 removed from the sphere is presented. The method consists in calculating the external neutron source required to keep level the neutron intensity in the boiler when x grams of 25 are removed from the sphere. Use is made of the experimentally determined neutron-distribution curves. It is found that 18.2 g of 25 subtracted from the sphere produces 1 percent change in K.
