Reply #242: Have you heard of Santa Susannah in the SImi Hills here in California?

Throughout the years, approximately ten low-power nuclear reactors operated at SSFL, in addition to several "critical facilities": a sodium burn pit in which sodium-coated objects were burned in an open pit; a plutonium fuel fabrication facility; a uranium carbide fuel fabrication facility; and purportedly the largest "Hot Lab" facility in the United States at the time. (A Hot Lab is a facility used for remotely cutting up irradiated nuclear fuel.) Irradiated nuclear fuel from other Atomic Energy Commission (AEC) and Department of Energy (DOE) facilities from around the country were shipped to SSFL to be decladded and examined.

At least four of the ten nuclear reactors suffered accidents. The AE6 reactor experienced a release of fission gases in March 1959, the SRE experienced a power excursion and partial meltdown in July 1959; the SNAP8ER in 1964 experienced damage to 80% of its fuel; and the SNAP8DR in 1969 experienced similar damage to one-third of its fuel. (see "Reactor accident sources" below).

In October 2006, the Santa Susana Field Laboratory Advisory Panel, made up of independent scientists and researchers from around the United States, concluded that contamination at the facility resulted in between 0 and 1,800 cancer deaths (the average estimate was 300 deaths). The report also concluded that the SRE meltdown caused the release of more than 458 times the amount of radiation released at Three Mile Island.<1>
