Work was continued on the evaluation of heavy-water moderating characteristics. Nuclear data were generated and results from critical experiments were evaluated for the purpose of fixing the prototype moderator tank diameter. Fabrication of approximately 80% of the CVTR Phase II hardware was completed. Calibration of the orifice and venturi meters for the hydrodynamic stability program was completed. TWo sets of preliminary results were obtained from the Cs/sup 137/ fission-product analysis of UO/sub 2/ samples from the first three rabbit capsules irradiated in WTR. The in-pile dynamic irradiation experiment loop has been in operation for three months for a total of 35 equivalent full-power days. Experimental brazing of specially shaped Zircaloy-2 fin material was carried out. Critical experiments to obtain differential and integrated control rod worths were begun. Drop measurements were made using sixteen control rods to determine the effective shutdown by this number of rods. The effect of the length and flow-rate parameters was studied, as well as the number of wire-wrapped rods necessary to achieive satisfactory mixing. (For preceding period see WCAP-4O48.) (W.L.H.)
