United Nuclear Corporation Naval Products Division





UNC Navel Products Division began fabricating reactor fuel elements in the 1950s for the Navel Nuclear Propulsion Program at the Montville , CT facility. This facility was authorized for the fabrication and inspection of unclad fuel components, encapsulation of the fuel into corrosion-resistant materials, and the assemblage of these into larger components or into reactor cores. In 1990, UNC began performing decontamination and decommissioning activities while concurrently completing work on existing contracts.

The United Nuclear Corporation was formed in March 1961 as a joint venture between three existing companies: Olin Mathieson Chemical Corporation, Mallinckrodt Corporation of America , and Nuclear Development Corporation of America . Initially, Olin became the majority stockholder and Nuclear Development Corporation was absorbed into the new company. It began with 1,400 employees.

Work included research and development, reactor system design, manufacture of nuclear fuel materials, reactor and core fabrications, fuel management, cold scrap processing, isotopes, and hot radiation energy sources.

The UNC Naval facility was operated by Olin Mathieson Chemical Corporation (April 1956 to May 31, 1961) and United Nuclear Corporation (June 8, 1961 to April 22, 1976) in New Haven , CT. The site had been used by United Nuclear Corporation to fabricate nuclear fuel components for the U.S. Government, was decommissioned in 1976, and removed from NRC License No. SNM-368 on April 22, 1976. The license was authorized by Atomic Energy Commission to use radioactive materials for manufacturing fuel for the naval reactor program at the site. In 1974, UNC announced the closing of the facility and transferred the inventory from the New Haven , CT location to the Montville , CT location. Subsequently, the SNM-368 license was terminated on June 8, 1994, following the decontamination and decommissioning of the Montville site, and the NRC released the facility for unrestricted use.



UNC decommissioning occurred over a three year period from 1990 - 1993 and the site license was terminated in 1994 with no future site use restrictions. Work was performed using in-house forces and specialized contractors. The facility was able to be decommissioned to a state of unrestricted release and is no being used as a gambling casino.
