The second in a series of three similar experiments, NORMANNA was located in hole U10cb in area 10 of the Nevada Test Site (NTS). The first experiment of this series (JARLSBERG) was conducted about one year earlier. The diameter of the emplacement hole was 2.18 m and the depth-of-burial of 203 m placed the working point in alluvium about 100 m above the Paleozoic contact and nearly 300 m above the static water level. NORMANNA was detonated on July 12, 1984 at 07:00 PDT. All phenomena appeared normal with a chimney collapse to the ground surface about 7 minutes later. The mean radius of the resulting crater was 54.1 m and its maximum depth was 8.8 m. No radiation arrivals were detected above ground and containment was satisfactory
