Project Faultless is a DOE site from 1967-1974 so workers are eligible to file both Part B and Part E claims.
Project Faultless was an underground nuclear test explosion conducted at the Central Nevada Test Site, which was part of a program designed to improve the United States' ability to detect, identify, and locate underground nuclear explosions. The Faultless test was conducted to determine the suitability of the area for additional seismic testing. Non-nuclear experiments designed to determine the behavior of seismic waves were also conducted in the vicinity.
Drilling for this project began July 1967; the operation period began on November 27, 1967. The shot was fired on January 19, 1968. On December 9, 1979, the site was placed in caretaker status and demobilization and restoration work was conducted during fiscal 1974.
Project Faultless nuclear explosion, January 1968, was designed to help determine the difference between seismic signals from nuclear explosions from earthquakes and was part of the Vela Uniform Project.
DOE's Legacy Management has a fact sheet on Central Nevada Test Site which contains information on Faultless.
