|Operation Roller Coaster|
|Test site||Tonopah Test Range|
|Number of tests||4|
|Previous test||Operation Storax|
|Next test||Operation Niblick|
Operation Roller Coaster was a series of open-air nuclear tests conducted by the United States on the Tonopah Test Range in 1963. The tests examined the dispersal of plutonium in storage and transportation accidents and were not expected to produce any nuclear explosive yield.
Corrective actions were taken at the Double Tracks and Clean Slate 1 sites. Contaminated soil was transported to the Area 3 Radioactive Waste Management Site in the Nevada National Security Site and the sites were revegetated.
The Clean Slate 2 and Clean Slate 3 sites remain contaminated pending an agreement between the state and federal government on the corrective action level.
