On February 11, 1943, a resolution was adopted by the
State Defense Committee to begin work on the creation of an atomic bomb. The general leadership was entrusted to the Deputy Chairman of the State Defense Committee
Lavrentiy Beria, who, in turn, appointed the head of the atomic project
Igor Kurchatov (his appointment was signed on March 10). The information received through intelligence channels facilitated and accelerated the work of Soviet scientists. Beginning at the end of 1945, a search began for a location for a secret facility, which would later be named KB-11. According to the memoirs of the academician
Yulii Khariton, the place for the future institute was researched carefully: it had to be located at a distance from the cities, since it was required to test various explosive structures so that active plutonium could be compressed and when combined, would exceed
critical mass. Having reviewed many locations, physicists came across a completely satisfying place in the former
Sarov Monastery (a famous saint that lived in the monastery, the
Saint Seraphim of Sarov, later became a patron saint of Russia's nuclear weapons) not far from
Arzamas (hence the names Arzamas-75 and Arzamas-16), on the border with the
Mordovian reserve. On the territory of the monastery, there was plant number 550 (hence the names Site 550 etc.), which produced mortar shells, guns, rockets for
BM-13 "Katyusha" rocket launchers, and other types of weapons. Behind the wall of the monastery there was a protected forest (the nature reserve is still very near to the
Sarov closed city) for hundreds of square kilometers, where test explosions could be carried out unnoticed.
Boris Vannikov commissioned a survey of the plant and on April 1, 1946
Sarov was chosen as the location of the first Soviet “nuclear center,” later famously known as “Arzamas-16.” On April 9, 1946, a resolution was adopted by the
Council of Ministers of the USSR- No. 805-327ss on the creation of KB-11 at
Laboratory No. 2 of the USSR Academy of Sciences (Kurchatov Institute). was appointed Head of KB-11 at the suggestion of Yu.B. Khariton, and the chief designer was
Yulii Khariton. In February 1947, by the decree of the
Council of Ministers of the USSR KB-11 was classified as a highly restricted enterprise and was transformed from a territory into a closed restricted zone. The settlement of Sarov was removed from the administrative structure of the
Mordovian Autonomous Soviet Socialist Republic and excluded from all records. Research laboratories and design departments of KB-11 began to develop their activities directly in Sarov in the spring of 1947. At the same time, the first production shops of experimental plants No. 1 and No. 2 were created. On March 3, 1949, the Council of Ministers of the USSR adopted decree No. 863-327ss/op on the construction of the USSR's first plant for the industrial production of atomic bombs as part of KB-11 in 1949-1950. On June 6, 1950, KB-11 was transferred from the Laboratory of Measuring Instruments of the USSR Academy of Sciences to the direct jurisdiction of The First Main Directorate under the USSR Council of Ministers, on the basis of which, in turn, on July 1, 1953, the
Ministry of Medium Machine Building was formed. By the end of 1951, the experimental mass production plant No. 551, which came into operation in the second half of 1951 (plant No. 3 KB-11), produced 29 atomic bombs
RDS-1. The storage of atomic bombs was also carried out on the territory of KB-11 in a specially erected underground reinforced concrete storage warehouse. In 1967, KB-11 was transformed into the All-Union Scientific Research Institute of Experimental Physics, which became part of the structure of the USSR Ministry of Medium Machine Building. Since February 1992, it is called the -
Russian Federal Nuclear Center - All-Russian Scientific Research Institute of Experimental Physics (
RFNC-VNIIEF). It is a federal state unitary enterprise of the nuclear weapons complex of the State Atomic Energy Corporation Rosatom (SC Rosatom). == Supercomputer ==
