Santa Susana Field Laboratory Area IV Information
Location
Chatsworth, California

The Santa Susana Field Laboratory (SSFL) is located in eastern Ventura County, California, and borders Los Angeles County. The SSFL is divided into four administrative and operational portions based on ownership and operations. Area IV was devoted to nuclear operations. It is Area IV that is covered under EEOICPA as a DOE facility.
Coverage includes, but is not necessarily limited to the following operations: The Energy Technology Engineering Center (ETEC), the Nuclear Development Field Laboratory (NDFL), and the Liquid Metal Engineering Center (LMEC). This also includes the Sodium Reactor Experiment Facility, the Kinetics Experiment Water Boiler Facility, the Water Boiler Neutron source (which is also known as the AE-6/L-85 Facility), the Organic Moderated Reactor, as well as facilities in Area IV associated with the Systems for Nuclear Auxiliary Power (SNAP) Program; the Sodium Graphite Reactor Critical Facility, the Shield Test Experiment/Shield Test Irradiation Reactor Facility, the Advanced Epithermal Thorium Test Facility, the Hot Lab Facility, the Fuel Storage Facility, the Radioactive Measurement Facility, the Radioactive Material Handling Facility, the Van De Graaff Accelerator Facility and the Radiation Instrument Calibration Laboratory.
Decontamination, decommissioning and demolition of radiological facilities in Area IV has been funded by the DOE beginning in the 1970’s, but predominantly since 1988.
Throughout the course of operations in Area IV, the potential for beryllium exposure existed.
