Thesis: S.B., Massachusetts Institute of Technology, Department of Nuclear Science and Engineering, 2018. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 41-43). / Latent heat energy storage (LHS) systems offer multiple advantages over sensible heat storage systems in terms of energy density, cost, and cycle efficiency. LHS systems use a phase change medium (PCM) that transfer heat at constant temperature. The use of metallic PCMs allows LHS to be used with high-temperature heat sources, such as the Fluoride-Salt-Cooled High- Temperature Reactor, and the use of a metallic heat transfer fluid (HTF) allows for a high rate of heat transfer. In this thesis, a 0.993 GWh thermal battery (ALTA) comprised of an aluminum PCM and sodium HTF is designed and evaluated in the steady-state. A novel rod design is also proposed to accommodate aluminum expansion as it changes phases. A final capital cost of $25.00/kWh is found, suggesting that ALTA is economically competitive. / by Kendall A. Fears. / S.B.
