Program for investigation of Zircaloy-2 hydriding

During the week of March 1, 1965, KW Reactor shut down with indications of a tube leak. Leak testing during the shutdown indicated a front Van Stone flange leak on tube 3065 and a suspect internal leak on tube 3075. During the tube removal process, there was indication of Zircaloy embrittlement on both tubes. Subsequent metallographic examination of samples taken from these tubes indicated the presence of case hydriding on the internal tube surface extending from approximately the end of the ac… more

Effective Specific Impulse of a Pulsed Rocket Engine

The specific impulse achieved in a pulsed rocket engine augmented with a fissioning nuclear bomb could be greater than that of any continuous flow engine. To a certain extent, this increase in specific impulse would be obtained at the expense of motor weight and average thrust. This paper considers the first of these limitations, motor weight, and estimates the highest effective specific impulse to be expected from a nuclear-pulsed rocket motor with respect to the weight of the motor.

Production test IP-740 phosphate capture subsequent to filtering. Final report

Alum is used as the coagulating agent in the water treatment process at Hanford. The bicarbonates present in Columbia River water react with the alum to form a loosely knit aluminum hydroxide molecule. Finely divided particulate matter and large organic molecules present in raw water are adsorbed by the floe particles. Partial is accomplished by settling in the basins; however, gravity filter beds remove the greater part of the suspension load. A polyacrylamide is added to the filter inlet stre… more
