And Storage

Increasing costs and security concerns with present fossil energy sources, plus environmental concerns related to CO2 emissions and the emergence of new technologies in the energy and transportation sectors set the stage for a marriage of convenience between coal and nuclear energy. As the price of oil continues to increase and supply becomes increasingly constrained, coal offers a secure domestic alternative to foreign oil as a source of liquid fuels. However, conventional technologies for converting coal to liquid fuels produce large quantities of CO2 that must be released or sequestered. Advanced nuclear technologies, particularly the High-Temperature Gas-Cooled Reactor (HTGR), have the potential to produce hydrogen via water splitting; however, the transportation and storage of hydrogen are significant barriers to the “Holy Grail”, the Hydrogen Economy. In a coal/nuclear marriage, the hydrogen and oxygen provided by nuclear energy are joined with coal as a source of carbon to provide liquid fuels with negligible CO2 release from the process. In combination with emerging hybrid vehicles, fuels based on a coal/nuclear marriage promise stable prices, increased domestic security and a reduction in CO2 emissions without the need to completely replace our transportation fuels infrastructure. The intent of this paper is to outline the technical basis for the above points and to show that process energy applications of nuclear energy can provide the basis for answering some of the tougher questions related to energy and the environment.

Theoretical Simulations

ABSTRACTWe review basic ideas behind state-of-the-art techniques for first-principles theoretical simulations of the phase stabilities and properties of alloys. We concentrate on methods that allow for an efficient treatment of compositional and thermal disorder effects. In particular, we present novel approach to evaluate free energy for strongly anharmonic systems. Theoretical tools are then employed in studies of two materials systems relevant for nuclear energy applications: Fe-Cr and Zr-based alloys. In particular, we investigate the effect of hydrostatic pressure and multicomponent alloying on the mixing enthalpy of Fe-Cr alloys, and show that in the ferromagnetic state both of them reduce the alloy stability at low Cr concentration. For Zr-Nb alloys, we demonstrate how microscopic parameters calculated from first-principles can be used in higher-level models.
