[ RadSafe ] Simi Valley Rx accident

Brian,

One of Sandy's reports to radsafe which mentions a Groundwater tritium  plume 
at Simi Valley (Santa Susana Test Laboratory Site, SSTL)

(http://www.vanderbilt.edu/radsafe/0409/msg00099.html) 

The following is a summary by Boing (who have absorbed Rocketdyne, one of  
the operators of the SSTL) of the Historical Site assessment of area IV which  
included the Sodium Reactor Experiment (SRE), this mentions that there was a  
accident that resulted in damage to 13 fuel elements in the reactor in 1959 and 
 that the reactor was shut down between July 27th 1959 and Sept 5 1960

A power point presentation that includes a very brief summary of the accident 
 at the SRE on page six and briefly mentions the tritium contaminated 
groundwater  issues on a couple of later slides.

Some further information on the accident, a class action lawsuit agaisnt  
Boeing and transcripts of interviews with some of the people involved in the  
civil case.  It suggests that up 100 times more I-131 was released from the  SRE 
accident than from TMI.  Hence the worse that TMI comments I guess.

The following are just some references I came across in another paper, (being 
 lazy) I haven't tried to search for any copies of the reports on the  
internet.  With luck they may help to find some more factual  information. 
Best wishes in your search, Julian
