De Soto Avenue Facility Information about Facility

In 1959, the Atomics International Division of North American Aviation moved to its new facility on De Soto Avenue. AEC/DOE work conducted at this location included engineering design, construction, and nuclear fuel fabrication. The facility also had a radiochemistry laboratory and a gamma irradiation facility. The fuel fabrication facility was used to produce a variety of different fuel elements for test reactors. AEC-sponsored work involving the manufacture of beryllium-containing parts also took place at this site. Fuel fabrication was terminated in 1984, however small scale laboratory research work on gamma irradiation and analysis of radioactive samples continued until 1995. A DOE-owned mass spectrometer at this location was removed from the premises and sent to the Pacific Northwest National Laboratory in 1995.

Remedial activities occurred at various times in the 1980’s followed by license termination by the Nuclear Regulatory Commission. In 1998, decontamination and decommissioning of the mass spectrometer laboratory, funded by the DOE was performed by The Boeing Company. In 1998, decontamination and decommissioning of the state-licensed gamma irradiation facility was performed by The Boeing Company.
