This report contains state-by-state fact sheets; selected scenarios for Arkansas, South Dakota, and the Coastal Plain; ERDA/DOD interfacing at selected bases in Region 5, other activities of interest; and a summary of action items/future plans. (MHR)

A method for the comparative evaluation of geothermal prospects in the Eastern United States is proposed and illustrated. Comparisons are based on quantified data from geologic, engineering, and socio-economic sources including temperature gradient, depth to basement, drilling costs, population, and distribution by town size, as well as energy use in residential, commercial, and industrial applications.

Experimental shock-tube data for the aerodynamic heating at the stagnation point on spherical bodies at superorbital and suborbital flight velocities (U/sub/0) have been compiled from a number of sources and compared to theoretical predictions. It was found that the empirical correlation given by Detra, Kemp and Riddell is remarkably close to a least-squares fit of the data. It is therefore recommended that their correlation be used for continuum flow theoretical predictions of the laminar hypersonic convective stagnation-point heating rate to spherical bodies in the region U/sub/0 - 6000 to 58,000 ft/sec.

The probability of accidents to tractor semitrailers is developed through analysis of accident frequency data in relation to season; geographical factors; road type, traffic and populatlon density; and type of carrier business. Maximum likelihood rates are developed for the potential carriers of radioactivity. Impact characteristics of accidents are studied through the analysis of mass, speed, and energy relations and the effect of these on vehicle and cargo damages is explored. (auth)

Nineteen papers presented at the Conference on the Transport of Radionuclides in Fresh Water Systems are given. Separate abstracts were prepared for 18 papers; one was previously abstracted for NSA. (M.C.G.)
