Nuclear Explosions for the National Economy used to put out runaway gas well fires and a methane blow out. There were in fact two programs: All together, the "Program 7" conducted 115 nuclear explosions. Among them: These explosions were financed by various ministries: 51 explosions were financed by the Ministry for Geology, 26 explosions were financed by the Ministry for Natural Gas, 13 explosions were financed by the Ministry for Oil, 19 explosions were financed by the MinSredMash itself (the predecessor of the Federal Atomic Energy Agency). There were two large explosions of 140 kilotons and 105 kilotons; all others were relatively small with an average
Merrimack Valley gas explosions in the low-pressure pipes. At the time of the accident, workers were replacing some of the low-pressure piping, but the procedure set out by Columbia Gas for doing this failed to include transfer of a regulator's pressure sensor from the old, disused piping to the new. As a result, when the old pipe was depressurized, the regulator sensed zero pressure on the low-pressure side and opened completely, feeding the main pipeline's full pressure into the local distribution network. Within minutes, buildups of natural gas were causing explosions and fires in houses across Lawrence, Andover and North Andover. Multiple explosions and
