KRYDOST: Containment data report
The KRYDOST event was detonated in hole U2co of the Nevada Test Site as indicated in figure 1.1. The device had a depth-of-burial (DOB) of 335 m in the Paintbrush tuff of Area 2, about 200 m above the Paleozoic and about 260 m above the standing water level, as shown in figures 1.2 and 1.3(l). Stemming of the 2.44 m diameter emplacement hole followed the plan shown in figure 1.4. An additional exploratory hole (Ue2co) was drilled 15-24 m to the south-south east of the emplacement hole. This hole was grouted from depth to the surface. A log of the stemming operations was maintained by Holmes & Narver(2). I During drilling, a deeply dipping fault was discovered to intersect both the emplacement and the satellite holes and an associated antithetic fault also found to intersect the emplacement hole as seen in figures 1.2 and 1.3. Detonation time was 13:00 PDT on May 6, 1982 and about 3 hours later a subsurface collapse to about half the DOB occurred. No radiation arrivals were detected above the ground surface and the KRYDOST containment was considered successful.
