Argonne National Laboratory is a federally funded research and development center in Lemont, Illinois, United States. Founded in 1946, the laboratory is owned by the United States Department of Energy and administered by UChicago Argonne LLC of the University of Chicago. The facility is the largest national laboratory in the Midwest. Argonne had its beginnings in the Metallurgical Laboratory of the University of Chicago, formed in part to carry out Enrico Fermi's work on nuclear reactors for the Manhattan Project during World War II. After the war, it was designated as the first national laboratory in the United States on July 1, 1946. In its first decades, the laboratory was a hub for peaceful use of nuclear physics; nearly all operating commercial nuclear power plants around the world have roots in Argonne research. More than 1,000 scientists conduct research at the laboratory, in the fields of energy storage and renewable energy; fundamental research in physics, chemistry, and materials science; environmental sustainability; supercomputing; and national security. Argonne formerly ran a smaller facility called Argonne National Laboratory-West (or simply Argonne-West) in Idaho next to the Idaho National Engineering and Environmental Laboratory. In 2005, the two Idaho-based laboratories merged to become the Idaho National Laboratory.Argonne is a part of the expanding Illinois Technology and Research Corridor.

The Track Imaging Cherenkov Experiment (TrICE) is a ground-based cosmic ray telescope located at Argonne National Laboratory near Chicago, IL. The telescope, which contains a Fresnel lens, eight spherical mirrors, and a camera with 16 multianode photomultiplier tubes, uses the atmospheric Cherenkov imaging technique to detect Cherenkov radiation produced when cosmic rays interact with particles in the Earth's atmosphere. The telescope is primarily a research and development tool for improving photomultiplier tube cameras and electronic systems for future gamma and cosmic ray telescopes. It is also used to study the energy and composition of cosmic rays in the TeV–PeV range, and the collaboration is currently conducting pioneering work in detecting direct Cherenkov signals from cosmic rays.

Darien (formerly Cass) is a city in DuPage County, Illinois, United States. Per the 2020 census, the population was 22,011. A southwestern suburb of Chicago, Darien was named after the town of Darien, Connecticut. Darien is just north of I-55 and Historic U.S. Route 66 (now Frontage Road). The entire south edge of the town borders Waterfall Glen.

Chicago Pile-5 (CP-5) was the last of the line of Chicago Pile research reactors which started with CP-1 in 1942. The first reactor built on the Argonne National Laboratory campus in DuPage county, it operated from 1954-1979.CP-5 was a thermal-neutron reactor using enriched uranium as fuel and heavy water as coolant and as a neutron moderator. It produced neutrons for use in research. The reactor had an output rating of 5 megawatts.Cleanup and decommissioning of the site of CP-5 was started in 1991 completed in 2000. The cleanup process included removal of all contaminated equipment and spent fuel, decontamination of the reactor vessel and associated plumbing, and removal of the spent fuel pool, reactor internals and the hot cell liner. The accessible areas of the structure have been certified as having radiation levels equivalent to background radiation.

Now the NBL Program Office, the New Brunswick Laboratory (NBL), was a United States government-owned and operated, center of excellence in the measurement science of nuclear materials. It was established in 1949 by the Atomic Energy Commission and was located in New Brunswick, New Jersey. It was relocated between 1975 and 1977 and was located, as a Federal enclave, on the site of Argonne National Laboratory, about 40 kilometers (25 miles) southwest of Chicago, Illinois. NBL was part the Department of Energy's Office of Science Chicago Office.NBL is the U.S. Government's Nuclear Materials Measurements and Reference Materials Laboratory and the National Certifying Authority for nuclear reference materials and measurement calibration standards. As an internationally recognized Federal laboratory, NBL provides reference materials, measurement and interlaboratory measurement evaluation services, and technical expertise for evaluating measurement methods and safeguards measures in use at other facilities for a variety of Federal program sponsors and customers. NBL functions as a Network Laboratory for the International Atomic Energy Agency (IAEA). NBL was reorganized into the NBL Program Office in 2016, and its nuclear reference materials were transferred to a new distribution center located near Oak Ridge, Tennessee. It is part of the National Nuclear Security Administration's Office of Defense Programs.

The Chicago Area Waterway System (CAWS) is a complex of natural and artificial waterways extending through much of the Chicago metropolitan area, covering approximately 87 miles altogether. It straddles the Chicago Portage and is the sole navigable inland link between the Great Lakes and the Mississippi River and makes up the northern end of the Illinois Waterway.The CAWS includes various branches of the Chicago and Calumet Rivers, as well as other channels such as the North Shore Channel, Cal-Sag Channel, and Chicago Sanitary & Ship Canal. The CAWS ends near the Lockport Navigational Pool, the highest elevated of the eight pools of the Illinois Waterway. There are three major locks within the CAWS, operated by the Army Corps of Engineers: the Chicago Harbor Lock, the Lockport Lock & Dam, and the T.J. O'Brien Lock and Dam.Artificial waterways connecting the Mississippi and Great Lakes systems via the Chicago area, over the Chicago Portage, began with the I&M Canal in 1848. The CAWS as it exists today began to take shape in 1900, with the construction of the Chicago Sanitary & Ship Canal to reverse the flow of the Chicago River (and eventually the Calumet River), which previously flowed into Lake Michigan, so as to instead flow toward the Mississippi River, thus carrying sewage away from the City of Chicago. Thereafter, additional artificial waterways were built that became part of the CAWS, such as the North Shore Channel, which runs inland from Wilmette to the Chicago River and was constructed in 1910, and the Cal Sag Channel, which provides a direct path from the Calumet River to the Illinois Waterway and was finished in 1922.In the 21st century, a focus of concern around the CAWS has been its potential role as a corridor for Asian carp to enter Lake Michigan. Suits in district court and before the United States Supreme Court have been unable to obtain an injunction requiring the connection between the CAWS and the Mississippi drainage to be closed.
