From heavy-water reactors to the world's largest accelerator: 23-year director of ITEP

After Khrushchev agreed not to arrest ITEP dissidents in 1956, Alikhanov told the four who had spoken at the party meeting: 'If you knew what you were doing, you're heroes. If you didn't, you're fools.'

A founder of Soviet nuclear physics. His positron spectroscopy (1933–40) and magnetic spectrometer built with Kozodayev laid the basis for Soviet nuclear electronics. In the atomic project he was scientific secretary of the Special Committee's council, leading heavy-water reactor development. In 1945 he founded Laboratory No. 3, later ITEP, directing it for 23 years and personally leading the USSR's first heavy-water research reactor (1949) and first industrial heavy-water reactor (1951). ITEP's 7 GeV synchrotron (1961) served as prototype for the 70 GeV Serpukhov accelerator, the world's largest in 1967. Never a Party member, he shielded staff during anti-cosmopolitan purges, signed the 'Letter of 300' against Lysenkoism, and in 1966 joined Kapitsa and Sakharov opposing Stalin's rehabilitation.

Civilian face of the nuclear program who chaired the State Atomic Energy Committee for 24 years

At the 1986 Chernobyl press conference, he declared: 'Science requires sacrifices.'

One of the founding generation of the Soviet atomic industry, Andranik Petrosyants began in the First Main Directorate administering the atomic bomb project and served from 1962 to 1986 as Chairman of the State Committee for the Use of Atomic Energy, the civilian face of the Soviet nuclear program and its international spokesman for peaceful uses. He is also remembered for telling the world press after the 1986 Chernobyl disaster that 'science requires sacrifices.'

The physicist who personally armed the first Soviet atomic bomb and built the second nuclear weapons center as its first scientific director

On 29 August 1949, Shchelkin signed for RDS-1 at the assembly workshop, inserted the initiating charge into the plutonium sphere, sealed the tower door last, and pressed the detonation button.

Kirill Shchelkin was a combustion and detonation physicist who formulated the theory of spin detonation and became a decisive figure in the Soviet atomic bomb project. On 29 August 1949 at the Semipalatinsk test site, he personally inserted the initiating charge into the plutonium sphere of RDS-1, sealed the tower door, and pressed the detonation button. In 1955 he was appointed the first scientific director and chief designer of the second Soviet nuclear weapons center, Chelyabinsk-70 (now VNIITF) in the Urals, where his team developed the first thermonuclear charge accepted into service by the Soviet Army. Awarded Hero of Socialist Labor three times alongside Kurchatov and Khariton, he was forced to retire in 1960 after a series of heart attacks.
