FAST MOLTEN SALT REACTOR-TRANSMUTER FOR CLOSING NUCLEAR FUEL CYCLE ON MINOR ACTINIDES
17th Symposium of AER on VVER Reactor Physics and Reactor Safety (2007, Yalta, Crimea (Ukraine, back then))
ACTINIDE TRANSMUTATION AND SPENT FUEL DISPOSAL
Creation fast critical molten salt reactor for burning-out minor actinides and separate long-living fission products in the closed nuclear fuel cycle (NFC) is the most perspective and actual direction. The reactor on melts salts – molten salt homogeneous reactor with the circulating fuel, working as burner and transmuter long-living radioactive nuclides in closed NFC, can serve as an effective ecological cordon from contamination of the nature long-living radiotoxic nuclides. High-flux fast critical molten-salt nuclear reactors in structure of the closed nuclear fuel cycle of the future nuclear power can effectively burning-out / transmute dangerous long-living radioactive nuclides, make radioisotopes, partially utilize plutonium and produce thermal and electric energy. Such reactor allows solving the problems constraining development of large-scale nuclear power, including fueling, minimization of radioactive waste and non-proliferation. Burning minor actinides () in MSR is capable to facilitate work solid fuel power reactors in system NP with the closed nuclear fuel cycle and to reduce transient losses at processing and fabrications fuel pins. At substantiation MSR-transmuter/burner as solvents fuel nuclides for molten-salt reactors various salts were examined, for example: LiF – BeF2; NaF – LiF – BeF2; NaF?-?LiF ; NaF?ZrF4 ; LiF?-?NaF?-KF; NaCl.
