A stainless steel sphere was heated to temperatures over 1000/sup 0/F and wind tunnel tested to obtain drag data. The tests were in conjunction with ERDA's Nuclear Power Supply Satellite Program. The purpose of the tests was to provide information on the drag characteristics of the sphere while it is heated so that terminal velocities can be calculated and impact behavior of the fuel spheres predicted. Results of the tests are presented. (TFD)

Design modifications of a five-probe focusing collimator coincidence radioisotope scanning system are described. Clinical applications of the system were tested in phantoms using radioisotopes with short biological half-lives, including /sup 75/Se, /sup 192/Ir, /sup 43/K, /sup 130/I, and /sup 82/Br. Data processing methods are also described. (CH)

The one-dimensional computer calculations described in this report were performed to simulate stress-wave propagation and kinetic energy transfer associated with subsurface cratering detonations in soils. A hypothetical 20-ton-yield nuclear explosive was assumed as the energy source, surrounded by a single soil material. Various soil descriptions were selected in order to systematically study the range of soil response to the nuclear detonation. The soils were representative of the layered mixtures of sand and clay found at the ESSEX high-explosive cratering sites near Ft. Polk, Louisiana. Soil properties analyzed in this study include water saturation, bulk density, failure envelope, and low-pressure bulk modulus.

Separate abstracts were prepared for 19 sections of this report. Abstracts were included for papers presented for publication during the period covered. (CH)
