Expertise has been developed in the area of BWR stability analysis, through detailed computational analysis using the coupled systems code TRACE/PARCS as well as consulting work for Nuclear Regulatory Commission (NRC) licensing activities.
The advanced reactor vendors have requested that the Department of Energy (DOE) and US Nuclear Regulatory Commission (NRC) provide a licensing framework to avoid uncertainties associated with licensing a new reactor technology.
The design and improvement of various generations of target designs have depended heavily on computational tools to forecast and virtually test the performance of SNS targets. In order to quantify the accuracy and validity of the predictions made by Computational Fluid Dynamics (CFD), a series of experiments have been performed utilizing state-of-the-art full field, non-intrusive measurement techniques. A set of full scale transparent test sections have been fabricated and installed to perform Particle Image Velocimetry measurements of the various SNS target designs.
Modeling of transport species (momentum,mass,energy) for several engineering problems requires undisturbed local information of the variables of interest. Conventional measurement techniques are usually intrusive and provide single-point readings.
Simulations and development activities with the thermal-hydraulic computer codes RELAP5-3D and TRACE
The advanced reactor concepts of the Generation IV International Forum (GIF) must successfully compete economically with other forms of energy production. The Economic Modeling Working Group (EMWG) analyzes the economic performance, including the total capital cost, levelized cost of electricity, and uncertainty associated with the different cost areas.
Baseload nuclear power struggles to compete with subsidized renewables and plentiful gas in deregulated markets. Integrating an alternative customer for low-demand periods can allow nuclear to operate at steady state while still providing sufficient resources for grid stability.
