As the United States supported the development of nuclear energy, there was a need to develop the technology related to the use of sodium and other liquid metals. The Liquid Metals Information Center (LMIC) was established in the late 1950s by the U.S. Department of Energy (DOE) predecessor agency, the Atomic Energy Commission (AEC), as a center of excellence for liquid metals technology.
As the LMIC mission evolved, it's name was changed into the Energy Technology Engineering Center (ETEC). The activities conducted at ETEC mostly involved the development and testing of components used in metallic sodium systems. Much of the liquid metal-related research conducted at ETEC supported the development of nuclear reactors at other locations.
In 1998, DOE decided to close the remaining ETEC operations. With the closing of DOE operations, the focus turned towards to the disposition of government property, cleanup of facilities, the investigation and remediation of soil and groundwater, demolition of facilities and site restoration. The Closure Project includes remediation of facilities involved in nuclear energy research.
