EnviroReporter.com wrote about the SNAP reactor’s two partial meltdowns in a September 23, 2004 Ventura County Reporter article entitled “In Hot Water – More good news about contamination from your friends at Rocketdyne,” where it was noted:

“At the meeting last week, Rocketdyne divulged that two new wells had high levels of tritium registering approximately 82,000 and 15,400 picocuries per liter near two former Systems for Nuclear Auxiliary Power (SNAP) reactors that were designed for use in space. The SNAP 8 Experimental Reactor Facility suffered a major accident in 1964 in which 80 percent of its nuclear fuel rods cracked and released radiation from the unconfined building. An adjacent SNAP 8 Development Reactor suffered a similar fate in 1969, with about a third of its fuel also cracking. Tritium readings near the most infamous Rocketdyne site, the Sodium Reactor Experiment that experienced a partial meltdown in 1959, registered only background levels of the radionuclide.”
