Argonne National Laboratory-West Information

ANL-W was a part of Argonne National Laboratory, operated by the University of Chicago. ANL-W was made up of six facilities: (1) the Experimental Breeder Reactor (EBR-I); (2) the Zero Power Reactor (ZPR-III); (3) the Argonne Fast Source Reactor (AFSR); (4) the Boiling Water Reactor Experiments (Borax I-IV); (5) the Experimental Breeder Reactor II (EBR-II); and (6) the Transient Reactor Test (TREAT) facility.

EBR-II and the Treat facilities were located on the southeastern portion of the Idaho National Engineering and Environmental Laboratory (INEEL); and EBR-I, ZPR-III, AFSR, and Borax I-IV were located on the southwestern portion of INEEL. The Argonne West name was given to the EBR-II and TREAT facilities when they were constructed in the late 1950s; the other four facilities were built starting in 1949 and were operational in the early 1950s, and were always managed and controlled by ANL, but had no specific name to differentiate them from the National Reactor Testing Station (NRTS), later to be known as INEEL. Because of that, we are using the “Argonne West” title to describe all of the Argonne-controlled facilities within INEEL. On February 1, 2005, INEEL and ANL-W became INL.

For nearly 40 years, ANLW led in the development of advanced nuclear reactor technology. Breakthroughs in the type of fuel used in nuclear-generated power, simplified reprocessing, reduction in the life span of nuclear wastes, and design of increasingly safer power plant systems all were developed at the ANLW complex.

Throughout the course of its operations, the potential for beryllium exposure existed at this site, due to beryllium use, residual contamination, and decontamination activities.
