UMich introductory engineering course aims to revolutionize nuclear energy through community engagement
A new course at the University of Michigan offered by the Nuclear Engineering and Radiological Sciences (NERS) Department seeks to address the lack of community engagement in the design of energy technologies by pioneering a socially engaged approach.

The tritium breeding and energy absorption in an inertial fusion energy (IFE) reactor chamber have been investigated with variable coolant zone thickness using different materials. Examples are given for HYLIFE-II (an IFE reactor design) and for magneto-hydrodynamic (MHD) energy conversion chambers using Flibe (Li2BeF4) as coolant. Investigations related to MHD are extended to the use of LiH, lithium, and Lil7-Pb83 eutectic as working fluid. Natural lithium is used in all cases, except in the case of LiPb, for which both natural and enriched options were calculated. To achieve a useful energy density for energy conversion purposes with a sufficient tritium breeding ratio (TBR = 1.1 to 1.2), coolant zone thicknesses must be 25 cm for LiH, 50 to 60 cm for Flibe, and 80 cm for lithium. The use of Lil7-Pb83 with natural lithium and with lithium enriched to 90% 6Li requires coolant zone thicknesses of 120 and 60 cm, respectively, to obtain a tritium breeding of TBR = 1.1, which gives an extremely low energy deposition density. This low density and the large coolant mass make LiPb unattractive for MHD and HYLIFE-II applications.
