Analyses were performed using the US Advanced Liquid Metal Reactor (ALMR) core design to determine the feasibility of using it as an {sup 99}Tc burner while reducing the sodium-void coefficient. A layer of {sup 99}Tc of variable thickness was inserted around the core midplane in Rows 2 through 5 and all blanket assemblies were replaced with fuel assemblies. The results indicate that a core with a 34-cm-thick layer in Rows 2 through 5 has the optimum characteristics of sodium-void coefficient, {sup 99}Tc destruction rate, and fuel enrichment.
