Various modifications were made to the Heavy Water Components Test Reactor (HWCTR) to preclude the formation of undesired gas voids in the moderator space of the reactor during operation at power. Final preparations were made for the initial operation of the reactor at power with no test fuel elements in the core. Good agreement was obtained in a comparison of data from the Process Development Pile (PDP) and the Pawling Lattice Test Rig (PLATR) on the nuclear reactivity of heavy water lattices of natural UO/sub 2/ rods. Fabrication was completed on twelve Zircaloy-clad tubular specimens of U --350 ppm Fe --900 ppm Al for capsule irradiations at Savannah River. The free gas contents of five Zircaloy-clad tubes of compacted uranium oxide were measured after the tubes were irradiated at Savannah River. (auth)
