On Thursday, Russian President Vladimir Putin announced that Russia was planning to launch the world's first nuclear power system with a closed fuel cycle in the Tomsk Region in 2030.
Fast neutron reactors make it possible to "burn" the most radioactive elements - minor actinides - and convert them into elements with much shorter half-lives, Chudakov said.
"In fact, actually bring them to equilibrium - to the same half-life with which we extract radioactive elements from the earth when we mine uranium. And this is already quite acceptable. In other words, it's clean, 'green' energy," he said.
