Beria in particular would use the intelligence as a third-party check on the conclusions of the teams of scientists.

Following this test, Kurchatov was bestowed with national honors and prizes in the recognition of his work.

Kurchatov worked under Ginzburg and took participation on the calculations that was given to him by Ginzburg. Unlike Ginzburg, Sakharov, and Yakov Zel'dovich, Kurchatov was only seen in the small scale of calculations, applying the basic nuclear weapon principle used in the smaller nuclear weapons that were developed under his directorship. In 1953, Soviet Union detonated its first thermonuclear device, codename Joe 4
