High-energy photon interrogation is a nondestructive technique that used to detect special nuclear materials and characterize waste. The development of such systems complex requires Monte Carlo simulations optimize system performance. rely on various scattering, absorption, photonuclear cross-section data. While the scattering absorption data have been extensively studied validated with experim...

This paper discusses the development of and proposed enhancements to a colorimetric test for the detection of uranium in biological samples such as urine. The goal of this work is to develop a technique for the detection of uranium that could: 1) be conducted rapidly and accurately; 2) would not require extensive sample preparation; 3) would not require expensive or complicated instrumentation;...

Several options for designing fast reactors to operate in the Breed-and-Burn (B&B) mode are compared and a strategy is outlined for early introduction of B&B reactors followed by a gradual increase in the fuel utilization of such reactors. In the first phase the fast reactor core will consist of a subcritical B&B blanket driven by a relatively small critical seed. As the required discharge burn...
