Aerial view of Mound Laboratories
Post-war construction of a permanent site for Dayton Project activities began in 1947. The lab was originally known as the Dayton Engineer Works. The lab began operations in 1948 and was managed by Monsanto. Mound produced detonators, cable assemblies, timers, firing sets, and other equipment. In 1954 Mound began working with Tritium. The lab disassembled bomb components, recovering the Tritium within and sending it for repurification at Savannah River Site. Mound supplied enriched non-radioactive isotopes. The lab also produced plutonium-238-powered thermoelectric heat sources called SNAP or Systems for Nuclear Auxiliary Power for the U.S. space program.
Mound was declared a Superfund site and was put on the National Priorities list in 1989. In[clarification needed] a decision was made to close the plant by 2006. Clean-up of the site began in 1995. Work with Tritium ended in 1997. The final closure date has been pushed back to at least 2010.[dated info]
