The reactor vessel for the Heavy Water Components Test Reactor was received at the plant site. Construction of the HWCTR was 75% complete by the end of June. Satisfactory preliminary results in the coextrusion of three Zircaloyclad thin-walled tubes of uradium metal indicated that the process is satisfactory for the fabrication of identical HWCTR test elements. Precision buckling measurements were made on 31-element clusters of 0.5-inch-diameter pelletized UO/sub 2/ rods in D/sub 2/O. Pressure drop data on the flow of boiling water at 1000 psia through seven-rod simulated fuel clusters were obtained. (auth)
