This record consists of a cover letter by G.W. Johnson of Lawrence Radiation Laboratory regarding distribution of the report titled "General Concept of a Deep Underground Shot, Rainier Event - Operation Plumbbob." The report addressess the feasibility of testing nuclear devices by means of completely contained underground explosions, thereby eliminating fallout and the expense of weather delays. As a result of favorable studies on underground testing, a deep underground (Rainier) was included in Operation Plumbbob. The plan was to drill a horizontal tunnel into the side of a hill in the Nevada Test Site and detonate a low-yield bomb at the end of the tunnel. If the experiment was successful, then higher-yield underground shots would be taken. Topics discussed include: date; device; physical environment (description of site, depth of burial, tunnel design); diagnostics; radiochemistry; nuclear radiation measurements; technique development experiments; shock growth; underground shot; hydrodynamic yield measurements; effects of the underground shot; core sampling; geophysical measurements; temperature and static pressure measurements; close-in earth motion measurements; on-site seismic measurements; contained nuclear detonation as a research tool; diamond production; hydronuclear and one-point safety tests; USGS activities; and rad-safe procedures.
