Mound Laboratory in Miamisburg, Ohio was an Atomic Energy Commission (later Department of Energy) facility for nuclear weapon research during the Cold War, named after the nearby Miamisburg Indian Mound.

Mound produced detonators, cable assemblies, timers, firing sets, and other equipment.

The lab disassembled bomb components, recovering the tritium within and sending it for repurification at Savannah River Site.

The lab also produced plutonium-238-powered thermoelectric heat sources called SNAP or Systems for Nuclear Auxiliary Power for the U.S. space program.

[1] Mound was declared a Superfund site and was put on the National Priorities list in 1989.
