Nuclear Explosions for the National Economy (sometimes referred to as ''Program #7''〔 〕), was a Soviet program to investigate peaceful nuclear explosions (''PNEs''). It was analogous to the US program ''Operation Plowshare''. 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.〔(The Nuclear Weapon Archive ), Chagan: The First Soviet "Industrial" Test〕 ==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: 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 per se, 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: * 39 explosions for the purpose of geological exploration (trying to find new natural gas deposits by studying seismic waves produced by small nuclear explosions) * 25 explosions for intensification of oil and gas debits * 22 explosions for creating underground storage for natural gas * 5 explosions for extinguishing large natural gas fountains * 4 explosions for creating channels and dams (including the Chagan test in Kazakhstan, and the Taiga test on the potential route of the Pechora-Kama Canal) * 2 explosions for crushing ore in open-pit mines * 2 explosions for creating underground storage for toxic wastes * 1 explosion to facilitate coal mining in an underground mine * 19 explosions were performed for research purposes (studying possible migration of the radioactivity from the place of the explosions). 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 yield of 12.5 kilotons. For example, one 30 kiloton explosion was used to close the Uzbekistan ''Urtabulak'' gas well in 1966 that had been blowing since 1963, and a few months later a 47 kiloton explosive was used to seal a higher pressure blowout at the nearby ''Pamuk'' gas field, successful experiments later cited as possible precedents for stopping the Deepwater Horizon oil spill.〔 U. S. Department of Energy contract no.: W-7405-Eng48.〕 The last nuclear explosion by the Program 7, codenamed Rubin-1 was performed in Arkhangelsk oblast on September 6, 1988. The explosion was a part of a seismic program for geological exploration. The Soviets agreed to stop their PNE program at the end of 1988 as a result of then president Mikhail Gorbachev's disarmament initiative. There are proponents for continuing the PNE programs in modern Russia. They (e.g. A. Koldobsky) state that the program has already paid for itself and saved the USSR billions of rubles and can save even more if it would continue. They also allege that the PNE is the only feasible way to put out large fountains and fires on natural gas deposits, and it is the safest and most economically viable way to destroy chemical weapons. Their opponents, including Alexey Yablokov, state that all PNE technologies have non-nuclear alternatives and that many PNEs actually caused nuclear disasters.〔 (A.V.
