CHEEDAM containment data report
The CHEEDAM event was detonated in hole U2et of the Nevada Test Site. The CHEEDAM device had a depth-of-burial (DOB) of 342 m in the Tunnel Beds Tuffs of area 2, about 85 m above the Paleozoic formation, and 240 m above the standing water level. Stemming of the 2.44 m diameter emplacement hole followed the plan shown in figure 1.4. A log of the stemming operations was maintained by Holmes & Narver. Detonation time was 09:00 PST on February 17,1983, and collapse progressed to the surface at about 1.1 hour after detonation. The resulting crater had a mean radius of 57.9 m and a maximum depth of 10.0 m. No radiation arrivals were detected above ground and the CHEEDAM containment was considered successful.
