Large neutron absorption resonances in the nuclides present in irradiation samples reduce the irradiating neutron flux at energies close to a resonance. In neutron activation analysis of optically thick samples with resonant isotopes, this self-shiel

Thermal response time is an important parameter for the control of fast reactors. Modern thermal hydraulic codes allow for the modeling of transient responses and can also be used to understand the dominant factors that affect them. However, simulati

Radiation detectors installed at major ports of entry are a key component of the overall strategy to protect countries from nuclear terrorism. While the goal of deploying these systems is to intercept special nuclear material as it enters the country

Long-life fast reactors receive considerable attention for their potential of using uranium efficiently, and because they can operate for extended periods without refueling. However, the main obstacle to achieving maximum operating times and fuel bur

Summary Edward Teller was the first to show that it would be possible for self-propagating fission waves to form in fertile nuclear materials. It is typically assumed that these waves would be asymptotically stable. However, we show here that couplin

Multigroup neutron transport models can be significantly faster than continuous energy methods. While minimizing the number of energy groups improves runtime, this causes the accuracy of a calculation to become strongly dependent on selected energy g

Variable cloud cover causes fluctuations in photovoltaic output that are hard to predict. As solar penetration increases optimizing the mix of back up generation and energy storage will become increasingly important. In these situations where suffici

Transient behavior in nuclear reactors is important in accidents and with reactivity control systems that are driven by thermal feedback. Here, we describe a transient finite difference model for a pin cell system. The fidelity of the model is shown

Escape probabilities are fundamental inputs in the calculation of self-shielded cross sections for multigroup neutron transport models. Rational approximations are often used to compute escape probabilities in geometries commonly encountered in nucle
