Godiva II
Godiva II was constructed inside a concrete building with 20-inch-thick (510 mm) walls and 8-inch-thick (200 mm) roof in a canyon a quarter-mile away from the control room.
In 1959, Los Alamos agreed to make Godiva II available to DOD contractors free of charge for 2 days each month, acknowledging its unique facility for radiation tests.
Godiva's success in creating intense bursts spurred development of similar pulsed reactors, which also suffered accidental excursions, for example: 28 May 1965 at the 1965 White Sands Missile Range (parts were thrown 15 feet); and 6 September 1968 at the Aberdeen Proving Ground (middle melted, disks warped and bolts stretched).
In December 2002, the U.S. Department of Energy announced it was to move its TA-18 testing equipment including the Godiva burst machine from the LANL to the Device Assembly Facility (DAF) at the Nevada Test Site (NTS).
