Nuclear Explosions for the National Economy (Russian: Ядерные взрывы для народного хозяйства, romanized: Yadernyye vzryvy dlya narodnogo khozyaystva; sometimes referred to as Program #7) was a Soviet program to investigate peaceful nuclear explosions (PNEs). It was analogous to the United States program Project Plowshare, although the Soviet one consisted of 124 tests. One of the better-known tests was Chagan of January 15, 1965. Radioactivity from the Chagan test was detected over Japan by both the U.S. and Japan in apparent violation of the 1963 Partial Test Ban Treaty (PTBT). The United States complained to the Soviets, but the matter was dropped.
History In November 1949, shortly after the test of their first nuclear device on September 23, 1949, Andrey Vyshinsky, the Soviet representative to the United Nations, delivered a statement justifying their efforts to develop their own nuclear weapons capability. He said:
The representative of the USSR stated that although the Soviet Union would have as many atom bombs as it would need in the unhappy event of war, it was using its atomic energy for purposes of its own domestic economy; blowing up mountains, changing the course of rivers, irrigating deserts, charting new paths of life in regions untrodden by human foot ... The Ukrainian SSR representative pointed out that, despite the fact that the USSR had come into possession of the secrets of atomic energy production, it had not swerved from its insistence upon the prohibition of atomic weapons. However the USSR did not immediately follow the U.S. lead in 1958 in establishing a program. Presumably, their position in support of a comprehensive nuclear testing ban stalled any efforts to establish such a program until the mid-1960s. When Nuclear Explosions for the National Economy was finally formally established, Alexander D. Zakharenkov, a chief weapons designer, was appointed head of the program. Initially, the Soviet program was focused on two applications, nuclear excavation and petroleum stimulation, similar to the U.S. program. However, interest in other applications quickly developed, and within five years the Soviet program was actively exploring six or seven applications involving participation by some ten government departments. Once underway the Soviets conducted a much more vigorous program than the Americans' Operation Plowshare, consisting of some 156 nuclear tests, some with multiple devices, between 1965 and 1989. These tests were similar in aims to the American effort, with the exception that six of the shots were considered of an applied nature, that is they were not tests as such, but were used to put out runaway gas well fires and a methane blow out. There were in fact two programs:
"Employment of Nuclear Explosive Technologies in the Interests of National Economy", also referred to as "Program 6", involved industrial underground PNEs and testing of new PNE technologies. As part of the program, 124 tests with 135 devices were conducted. Primary objectives of the program were water reservoir development, dam and canal construction, and creation of underground cavities for toxic waste storage. "Peaceful Nuclear Explosions for the National Economy", also referred to as "Program 7", involved testing of industrial nuclear charges for use in peaceful activities. Nuclear detonations were conducted with the stated purpose of searching for useful mineral resources with reflection seismology, breaking up ore bodies, stimulating the production of oil and gas, and forming underground cavities for storing the recovered oil and gas. The "Program" numbers come from the USSR's classification system of nuclear explosions, the first five programs designating various phases of nuclear weapon development.
All together, the Program 7 conducted 115 nuclear explosions. Among them:
