paragraph_text: Post–war Soviet Ukraine
  
  The republic was heavily damaged by the war, and it required significant efforts to recover. More than 700 cities and towns and 28,000 villages were destroyed. The situation was worsened by a famine in 1946–1947, which was caused by a drought and the wartime destruction of infrastructure, killing at least tens of thousands of people. In 1945, the Ukrainian SSR became one of the founding members of the United Nations (UN), part of a special agreement at the Yalta Conference, and, alongside Belarus, had voting rights in the UN even though they were not independent. Moreover, Ukraine once more expanded its borders as it annexed Zakarpattia, and the population became much more homogenized due to post-war population transfers, most of which, as in the case of Germans and Crimean Tatars, were forced. As of 1 January 1953, Ukrainians were second only to Russians among adult " special deportees ", comprising 20% of the total.
  
  Following the death of Stalin in 1953, Nikita Khrushchev became the new leader of the USSR, who began the policies of De-Stalinization and the Khrushchev Thaw. During his term as head of the Soviet Union, Crimea was transferred from the Russian SFSR to the Ukrainian SSR, formally as a friendship gift to Ukraine and for economic reasons. This represented the final extension of Ukrainian territory and formed the basis for the internationally recognized borders of Ukraine to this day. Ukraine was one of the most important republics of the Soviet Union, which resulted in many top positions in the Soviet Union being occupied by Ukrainians, including notably Leonid Brezhnev, General Secretary of the Communist Party of the Soviet Union from 1964 to 1982. However, it was he and his appointee in Ukraine, Volodymyr Shcherbytsky, who presided over the extensive Russification of Ukraine and who were instrumental in repressing a new generation of Ukrainian intellectuals known as the Sixtiers.
  
  By 1950, the republic had fully surpassed pre-war levels of industry and production. Soviet Ukraine soon became a European leader in industrial production and an important centre of the Soviet arms industry and high-tech research, though heavy industry still had an outsided influence. The Soviet government invested in hydroelectric and nuclear power projects to cater to the energy demand that the development carried. On 26 April 1986, however, a reactor in the Chernobyl Nuclear Power Plant exploded, resulting in the Chernobyl disaster, the worst nuclear reactor accident in history.
