The physical behavior of the mockup burnable poison rods, containing 0.5, 1.0, and 2.0 wt % Gd/sub 2/O/sub 3/ in natural uranium oxide pellets, has been studied in critical experiments. Specifically, the reactivity effects, thermal-neutron density distributions, and overall temperature coefficient of reactivity were of interest when related to the poison effect. It was shown that the poison reactivity effect did not change greatly when the Gd/sub 2/O/sub 3/ content of the fuel pellets was >0.5 wt %. The poison also made the temperature coefficient of reactivity more negative. Some analytical methods are given, and the calculated and experimental results are compared.
