On results of the decommissioning of Georgian nuclear research reactor IRT bygrouting and its conversion into a new low power nuclear facility

摘要

The research nuclear reactor IRT- M belonged to the Institute of Physics of GeorgianAcademy of Sciences. Its operation came to an end in 1988. Taking into account the lack of financial andtechnical resources, the Institute of Physics issued decision to shut down reactor by grouting the radioactive lowpart of the reactor tank, where the reactor core is placed. It gave us the possibility to carry out decommissioningof the reactor using modest finances. Installing a new low-power facility (about 50 kW, nuclear fuel -20%enrichement by 235U) onto the free part of the reactor tank was also considered. The proposed facility is designedto carry out neutron-activation for producing of radionuclides for medicine, curing tumors by Boron NeutronCapture Therapy (BCNT) and others aims. Solving of all these tasks is very important for Georgia. The plan fordismantling of remaining cooling and other auxiliary systems of the reactor IRT-M has already been elaborated.All activities are performed within the frame of new IAEA TC project GEO/3/002.
