Semipalatinsk Info


The Semipalatinsk Test Site (STS) was the primary testing venue for the Soviet Union's nuclear weapons. It is located on the steppe in northeast Kazakhstan (then the Kazakh SSR), south of the valley of the Irtysh River. The scientific buildings for the test site were located around 150 km west of the town of Semipalatinsk (later renamed Semey), near the border of East Kazakhstan Province and Pavlodar Province with most of the nuclear tests taking place at various sites further to the west and south, some as far as into Qaraghandy Province.
The site is also known variously by its postcode Semipalatinsk-21 (it was common practice for secret Soviet installations to be referred to only by their nondescript postcode), the Semipalatinsk Polygon, and latterly the National Nuclear Center of Kazakhstan.
