Particularities of the Dismantling of the Intra-Vessel Structures of the RFT Reactor

Resumo

The results of work on dismantling the graphite masonry and reactor structures of the RFT research reactor at the National Research Center Kurchatov Institute are presented. Remote-controlled technology and remote-sensing measurements of contamination levels were used to perform the operations of removing radioactive structures. Such methods have significantly reduced the impact of the radiation on the workers, the general public living in nearby urban areas, and the environment. The measurements of the dose rate in the masonry channels are presented and the total ¹³⁷Cs activity in the graphite is determined.
