Port city (pop., 1999: 269,600) on the Irtysh (Ertis) River, eastern Kazakhstan. It was founded as a Russian fort in 1718 and was moved to its present site in 1778, at the junction of caravan trails; before 1917 more than 11,000 camels passed through the city annually. In the early 20th century it was connected by rail to Siberia and other parts of Central Asia. It has one of the largest meat-packing plants in Kazakhstan. Its name was changed after Kazakhstan attained independence in 1991.

Semey (Семей; also transliterated as Semij or Semei, and known by its former name of Semipalatinsk (Семипалатинск)) is a city in Kazakhstan, in the northeastern province of East Kazakhstan, near the border with Siberia, around 1,000 km north of Almaty, and 700 km southeast of the Russian city of Omsk, along the Irtysh River.
In 1949 a site on the steppe 150 km (100 miles) west of the city was chosen by the Soviet atomic bomb programme to be the location for its weapons testing. For decades Kurchatov -- the secret city at the heart of the test range named for Igor Kurchatov, father of the soviet atomic bomb -- was home to many of the brightest stars of Soviet weapons science. The Soviet Union operated the Semipalatinsk Test Site (STS) from the first explosion in 1949 until 1989; 456 nuclear tests, including 340 underground and 116 atmospheric tests, were conducted there.
Semey has suffered serious environmental and health effects from the time of its atomic prosperity: nuclear fallout from the atmospheric tests and uncontrolled exposure of the workers, most of whom lived in the city, have given Semey and neighboring villages high rates of cancer, childhood leukemia, impotence, and birth defects.
Modern Semey is a bustling university town with a population nearing 300,000. Its proximity to the border, and the large expatriate scientific community attached to the university and the STS labs, gives Semey a more Russian character than other Kazakh cities.
The oblast (oblysy) of Semipalatinsk has been merged with the bigger East Kazakhstan Province whose capital city is Oskemen.
The city has a museum to commemorate Abay Qunanbayuli, and has both a museum of, and a street named after, Dostoevsky.
