In this letter the Soviet minister proposed to the Soviet government to concentrate the nuclear research in Ukrainian Institute of Physic and Technology (UIPhT) and to locate in Kharkov the nuclear scientists from Leningrad Institute of Physic and Technology because Kharkov institute had very good base for the nuclear studies.

In any case this letter of people’s commissar recognized the prominent role of the Ukrainian Institute of Physic and Technology (UIPhT) in the Soviet nuclear science.

This letter informed the Academy of Sciences that UIPhT asked the government of the Ukrainian Soviet Republic to allocate 75 thousand rubles for designing of the cyclotron, and 1,5 million rubles for its building. The State Plan asked an advice on necessity to build the cyclotron.

This document is an answer to the letter from State Plan of Ukrainian Soviet Socialistic Republic to Academy of Sciences of USSR “About Rationality to Construct Cyclotron in UIPhT” (22 Feb 1940). The answer of academician Petr Kapitsa to this letter was very critical. Kapitsa wrote that UIPhT “during the last several years built a number of research installation but did not finish them. However it started to build new installations. Such activities of UIPhT can’t be considered as normal”. So Petr Kapitsa discouraged building a cyclotron in UIPhT, and this was one of the reasons why this institute did not become the leading nuclear center in USSR.
