DOE has completed the radiological surveys and has taken remedial actions to decontaminate and decommission DOE contaminated areas that were found in the SEF complex and Bldg. 003.
The Sodium Reactor Experiment (SRE) Facility at the Santa Susana Field Laboratories in Ventura County, California, was built between 1955 and 1957. The 20Mwt sodium-cooled, graphite-moderated, thermal reactor was operated from April 1957 - February 1964.
The action assessed is the DOE release for unrestricted use of the Sodium Reactor Experiment facility located at Rockwell International's Santa Susana Field Laboratory approximately 29 miles northwest of Los Angeles, California.
The SRE was a complex of buildings used to support the earliest nuclear research in commercialized nuclear power in Area IV.
The Sodium Reactor Experiment (SRE) located at the Rockwell International Field Laboratories northwest of Los Angeles was developed to demonstrate a sodium-cooled, graphite-moderated reactor for civilian use.
