Director’s R&D Fund— Advanced Energy Systems energy efficiency improvements of 20–30% in excess of conventional, gas-compression refrigeration technology. Magnetic heating and cooling occur with the magnetization and demagnetization of MCE materials and can be incorporated into highly efficient heat pump cycles. The project directly supports the Building Technologies Program’s High Priority R&D goal of “developing new, highly energyefficient HVAC equipment that will significantly reduce overall energy needs in new and existing commercial buildings.” Results and Accomplishments This project uses an integrated computational and experimental approach. A computational model of the MCE in Ni 2 MnGa based on ORNL’s leading first-principles modeling code, Locally Self-consistent Multiple Scattering (LSMS), has been developed and run on 28,800 Jaguar processors using 200 Monte Carlo “walkers” for a 144 atom supercell. The results of this model are used to fit a Heisenburg model to generate the density of magnetic states. To enhance the ability to measure the properties of multiple materials, we have developed the capability for discovery of new MC alloys using combinatorial sputtering. The combinatorial equipment has been designed, fabricated, and is in the process of being installed. While the combinatorial equipment was being built, bulk alloys of material were prepared for testing in experiments at the <strong>National</strong> High Magnetic Field <strong>Laboratory</strong> and in ORNL’s 9 tesla superconducting magnet. These alloys were suggested by both our computational modeling efforts and some that have been widely investigated as standards for comparison, and some of the Ni 2 MnGa alloys included small amounts of iron and/or copper to examine the effects of these elements on the structural and magnetic transition temperature. These materials were characterized using differential scanning calorimeter (DSC) and superconducting quantum interference device (SQUID) techniques. The results of testing the bulk alloy materials demonstrated that it is possible to control the structural and magnetic transition temperatures using small amounts of iron and copper and that it is possible to manipulate the Curie temperature using these materials.

The continued international support for research in fusion energy despite limited success in delivering on past promises is a testimony to its remarkable possibilities. The ITER international experimental reactor will begin operation in the next decade and will subsequently generate relatively long-pulse burning plasmas, producing up to 10 times 120
Director’s R&D Fund— Advanced Energy Systems the energy required for operation. This will be a substantial initial step towards the realization of a fusion power plant. The purpose of this project is to develop a world-class fusion technology program at ORNL that builds on existing areas of strength within the lab and addresses technology gaps in fusion engineering, particularly in the area of materials for fusion applications. This is done by providing highend multiphysics computational analysis, mechanical design, and project engineering, to participate in the development of critical experimental facilities and projects that will bridge the gaps between ITER and commercially viable fusion power. Mission Relevance This project is specifically relevant to the energy resources mission of DOE. When the objectives of the project are realized, ORNL will have developed capabilities that will enable technologies for closing some of the technology gaps that currently stand in the way of realizing commercial power through magnetically confined fusion energy. Particularly, progress will be made towards the planning and construction of facilities (such as a Fusion Nuclear Science Facility, a Plasma Materials Test Stand, a Test Blanket Module, or collaboration on a compact Stellarator) for solving plasma material interface issues, which are among the most critical for the development of a fusion power plant. Results and Accomplishments Flow profiles and thermal transfer for helium flow through roughened pipes for a Dual Cooled Lead Lithium (DCLL) test blanket have been completed using the computational fluid dynamics capability of the ANSYS multiphysics code, and these results have been validated with published empirical results. The ANSYS multiphysics code has been used to perform structural and modal analysis on stellarator design components. A preliminary study on irradiation effects on a copper alloy has been performed to analyze the suitability for the Fusion Nuclear Science Facility (FNSF) centerpost. In addition, a twodimensional design optimization study has been completed on the cooling channel design for the FNSF centerpost. 121
