Following several months of intensive field work, environmental cleanup crews have wrapped up a campaign to address contaminated equipment and debris at two historical nuclear testing locations on the Tonopah Test Range in Nevada.
Field crews worked throughout the summer at To nopah’s Clean Slates II and III sites, removing contaminated drums, shipping containers, debris piles, and machinery, before packaging the waste for disposal. This recent cleanup effort follows an initial campaign that took place in the late 1990s.
On December 3, 2014, Nevada National Security Site (NNSS) workers transported the Clean Slates waste to the NNSS’ low-level radioactive waste management facility for permanent disposal in an engineered disposal unit.
“This was a joint effort,” said federal EM Operat ions Manager Rob Boehlecke . “NNSS contractors, the Air Force, and Sandia National Laboratorie s all came together and executed a seamless campaign.”
The Nevada Field Office, under the U.S. Department of Energy’s (DOE) National Nuclear Security Administration, is responsible for environmental restoration work at the NNSS and Tonopah Test Range. Restoration commitment s, processes and timelines are identified in a formal agreement between the DOE and the State of Nevada.
In early December 2014, Clean Slates waste packages were disposed at the NNSS’ Area 5
Radioactive Waste Management Complex.
Clean Slates II and III were pa rt of Operation Roller Coaster – a series of experiments in 1963 designed to test the safety of nuclear devices. Though these experiments did not result in a nuclear yield, they caused the disper sal of various surface contaminants.
Clean Slates and Double Track Sites
In May and June 1963, Project Roller Coaster conducted a series of four nuclear weapons destruction tests that resulted in plutonium dispersal in surrounding soils. Three of these tests were conducted within the boundaries of TTR, the fourth was conducted on the NTTR just west of TTR.

Clean Slate was a nuclear weapons safety test. Basically use some high explosive to dispere plutonium. [Hey, what could go wrong.] It took place in 1963, and now in 2014, it supposedly is "clean." A mere 51 years.
To be clear here, this was not a test where the bomb went critical. More like what would happen if a bomb was accidentally dropped and the high explosive went off. What are the odds of that happening...uh well....

Do you know what the status is of this area, about 7.5 miles NW of Groom Lake?
I cannot remember the details, I have it marked on GE as "Alpha Contaminated Area", and recall it being a spot where plutonium was dispersed?

That film was worth the watch. I only knew about half of those broken arrows. They must have removed the copyright notice when uploading the film to youtube, but it looks like the early 1970s at the latest Bush II and Obama have greatly reduced the number of warheads. The highly enriched nuclear material was supposely turned into nuclear power plant fuel. My only complaint about the film was given the low resolution of youtube and the old footage, it was tough to tell was what stock footage and what was CG or whatever was done in the 1970s.
