Aleksandr Leipunskii
Aleksandr Ilyich Leipunskii (; ; 7 December 1903 – 14 August 1972) was a Soviet physicist. He was born in the small village of Drahle, Grodno Governorate, Russian Poland. In 1921, he entered the Leningrad Polytechnic Institute, graduating in 1926. He then joined the Leningrad Physico-Technical Institute, where he studied atomic interactions with electrons and molecules. In 1930, he began research into nuclear physics. He helped organize the Ukrainian Physics and Technology Institute in Kharkiv and became its director. In 1934, he was sent to England for a year as a visiting researcher at the Rutherford Laboratory. In September 1937 Leipunskii was arrested as a German spy in connection with the UPTI Affair, but later released. After being evacuated to Ufa, in 1941 he also became a head of the Institute of Physics of the Academy of Sciences of the Ukrainian SSR and held that post until 1949.

Its population is 125,376 at the 2021 census. History The history of Obninsk began in 1945 when the First Research Institute Laboratory "V", subsequently called the Institute of Physics and Power Engineering (IPPE) was founded. On June 27, 1954, Obninsk started operations of the world's first nuclear power plant to generate electricity for a power grid. The city was built next to the plant in order to support it. Scientists, engineers, construction workers, teachers and other professionals moved to Obninsk from all over the Soviet Union. Town status was granted to Obninsk on June 24, 1956.

Hero Of Socialist Labor
The Hero of Socialist Labour () was an honorific title in the Soviet Union and other Warsaw Pact countries from 1938 to 1991. It represented the highest degree of distinction in the USSR and was awarded for exceptional achievements in Soviet industry and culture. It provided a similar status to the title of Hero of the Soviet Union, which was awarded for heroic deeds, but differed in that it was not awarded to foreign citizens. History The Title "Hero of Socialist Labour" was introduced by decree of the Presidium of the Supreme Soviet of the Soviet Union on December 27, 1938. Originally, Heroes of Socialist Labour were awarded the highest decoration of the Soviet Union, the Order of Lenin, and a diploma from the Presidium of the Supreme Soviet of the Soviet Union. In order to distinguish the Heroes of Socialist Labour from other Order of Lenin recipients, the "Hammer and Sickle" gold medal was introduced by decree of the Presidium on 22 May 1940, to accompany the Order of ...

Fast Breeder Reactor
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be Nuclear fuel, fueled with more-commonly available isotopes of uranium and Isotopes of thorium, thorium, such as uranium-238 and thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors. These materials are called fertile materials since they can be bred into fuel by these breeder reactors. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use. These extra neutrons are absorbed by the fertile material that is loaded into the reactor along with fissile fuel. This Irradiation, irradiated fertile material in turn transmutes into fissile material which can undergo Nuclear fission, fission reactions. Breeders were at first found attractive because they made more complete use of uranium fuel than light-water reactors, but interest declined after the 1960s as more uranium reserves ...
