Lemont, Illinois

The Lemont Central Grade School is a former school building at 410 McCarthy Road in Lemont, Illinois. The school was built in 1869 to replace Lemont's first school, which opened in 1836 when the area was still largely rural. Locally quarried limestone was used to construct the school; at the time, limestone production was one of the city's main industries. Architect John Barnes of Joliet designed the Victorian building. As the city's population grew considerably during the construction of the Chicago Sanitary and Ship Canal in the 1890s, an annex was placed on the school in 1896 to accommodate additional students. The school operated until building safety issues forced its closure in 1974; at the time, it was the oldest continuously operating school in the state. The building has since been converted to condominiums.The building was added to the National Register of Historic Places on March 7, 1975.

The Lemont Downtown Historic District is a commercial historic district encompassing 14 city blocks in downtown Lemont, Illinois.

The commercial buildings in the district exhibit a variety of common building types seen between 1850 and 1950; one-part, two-part, gable-front, and false-front buildings are all present, and their designs feature Italianate, Commercial, and revival style architecture.

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).

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.
