Argonne National Laboratory–West

State: Idaho
Location: Scoville
Time Period: 1949-2005
Facility Type: Department of Energy

Facility Description

Argonne National Laboratories – West was a part of Argonne National Laboratory, operated by the University of Chicago. ANLW was located on the southeastern portion of the Idaho National Engineering and Environmental Laboratory. On February 1, 2005 the Idaho National Engineering and Environmental Laboratory and Argonne National Laboratory – West became the Idaho National Laboraotry (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 exposureexisted at this site, due to beryllium use, residual contamination, and decontamination activities.

General Site Information

In 1949, the U.S. Atomic Energy Commission (AEC) established the National Reactor Testing Station in Idaho as a Federal reservation to build, test, and operate nuclear reactors. The site constructed and operated a variety of support facilities and equipment. In February 1951, AEC opened the Idaho Division of Argonne National Laboratory (which is now ANL-W) within the boundaries of the site. In 1974, the site became the Idaho National Engineering Laboratory, which in 1997 became the Idaho National Engineering and Environmental Laboratory. On February 1, 2005, the site became INL and combined the operations of the Idaho National Engineering and Environmental Laboratory, ANL-W, and the Idaho Cleanup Project, which is working on closure of inactive portions of the site. (For convenience, this Technical Background Document [TBD] refers to the site as INL.)

INL is an 890-mi2 reservation with a maximum distance of about 39 mi from north to south and 36 mi from east to west. It is 30 to 60 mi west of Idaho Falls, Idaho. Major site-related research facilities and offices are in Idaho Falls. The site is on the Snake River Plain in southeastern Idaho at an elevation of about 5,000 ft and is above the Snake River Plain aquifer.

INL is unique among DOE facilities because it is a large complex site with many independent technical areas, contractors, goals, and missions. Table 2-1 lists the prime contractors and the years during which they operated the site. The prime contractor provided some services to the other contractors and operated most of the facilities. Some of the specific technical areas were operated in part by other contractors during the tenure of the prime contractor. Table 2-2 lists those facilities and technical areas and the years during which contractors other than the prime contractor operated them.
