The EEOICPA was passed in 2000. It provides compensation to workers who became ill as a result of their employment manufacturing nuclear weapons in the USA, as well as their spouses, children, and grandchildren. Metallurgical Laboratory EEOICPA coverage is available for qualified former Workers and their families.

Are you eligible for compensation? If you or a family member worked at this or another DOE facility and became ill, you may be entitled to compensation of up to $400K plus medical benefits.

Here, we have compiled publicly available information and documentation about the facilities covered by the Act to clarify how their activities relate to the Energy Employees Occupational Illness Compensation Program Act.

Metallurgical Laboratory

Also Known As: Eckhardt Hall (+ West Stands, New Chem. Lab and Annex, Ryerson Physical Lab, Kent Chem. Lab), Met Lab
State: Illinois
Location: Chicago
Time Period: BE 1942-1946; AWE:1942-1946; Res. Rad. 1947 – 1981;DOE 1982 – 1984; 1987*
Facility Type: Atomic Weapons Employer, Beryllium Vendor, Department of Energy

Facility Description:
The University of Chicago’s Metallurgical Laboratory (Met Lab) was involved in early uranium metallurgical work as part of the Manhattan Project. The first self-sustaining nuclear chain reaction was achieved at the university in a “pile” called the Chicago Pile 1, built by Enrico Fermi and his Met Lab colleagues. The Met Lab is the direct predecessor of Argonne National Laboratory into which all Met Lab functions were transferred in 1946.

Beryllium use at the Metallurgical Laboratory is linked with experimental studies in determining whether to use graphite, heavy water or beryllium as a pile moderator. Graphite was the ultimate choice for Fermi’s pile. *In 1982-1984 and 1987 environmental remediation was conducted in Eckhart Hall, Jones Laboratory and Ryeson Hall. Only environmental remediation work performed under contract to the DOE performed in these buildings as DOE facility employment during the time period.

Contractor: University of Chicago (1942-1946)

Metallurgical Laboratory is listed as an Atomic Weapons Employer (AWE) site from 1942-87, as a Beryllium Employer (BE) site from 1942-46, and as a Department of Energy (DOE) site from 1982-84 and 1987.
