This report, sent from the Council of People's Commissars of the USSR to V.M. Molotov, informs Molotov that the project for Uranium enrichment was prepared by F. Lange and his colleagues by December, 1942. The installation of this project was planned to be produced outside of Ukraine, in a facility in Kasan.

This famous, de-classified document officially started the Soviet atomic project aimed at producing the nuclear bomb. The second point of this document orders the Ukrainian Academy of Sciences to establish a plan for the project of Uranium enrichment. F. Lange, a scientist from the Ukraine Institute of Physics and Technology, was appointed as head of this project because he worked previously on theoretical aspects of Uranium enrichment.

In this document, leading Soviet scientists criticize the idea of Kharkov physicists to use Uranium in military goals, because they do not believe it is possible to realize nuclear fission in the current practical conditions faced. The Soviet National Committee of Defence received these skeptical assessments in 1941 and decided not to develop the military nuclear program.

Kharkov Institute scientists proposed in this document the concrete steps to build a nuclear weapon. The document demonstrates that Ukrainian physicists understood how to receive weapons grade uranium and elaborated concrete technical proposals to achieve this goal through uranium enrichment in centrifuge.

In this letter two nuclear scientists from UIPhT described the construction of the nuclear bomb and proposed to start activities in producing of the nuclear arsenal and make these activities secret. Two Ukrainian physicists were first Soviet scientists who revealed the method of producing a nuclear weapon (of course they did not know about the similar inventions of western scientists which were made at the same time under great secrecy).
