“…Thus, the radiation background from irretrievable losses of 90Sr alone will be more than 100 times more than the radiation background from uranium with accompanying isotopes extracted from the earth. The study presented in [7] indicates that the radioactivity of 137Cs (5.65•1015 Bq) included in irretrievable losses corresponds with the radioactivity from irretrievable losses of 90Sr. Only 2 of these isotopes will lead to an excess of background radiation compared to natural uranium by almost 300 times over 100 years.…”

“…In [7], the example of 90Sr, which has a half-life of 28.78 years, was used to assess the consequences of large-scale recycling of spent nuclear fuel. The study assumes that in the long term, irretrievable losses will amount to 0.1%.…”

“…This state will be characterized by constant radioactivity. It is shown in [7] that for a level of irretrievable losses equal to 0.1%, the equilibrium amount will be more than 4% of the total amount of recycled SNF in the annual volume. This will be equivalent to 4.8•1015 Bq.…”

“…Radioactivity accumulated in irretrievable losses (0.1%) after recycling spent fuel of PWR with respect to its annual demand for natural uranium [7]. Now the background values of global radiation pollution are 0.045 Ci/km2 for 90Sr, 0.08 Ci/km2 for 137Sc, and 0.005 Ci/km2 for 239Pu [9].…”

The paper is concerned with an alternative to the existing concept of expanding the nuclear energy fuel resources in terms of fissile isotopes by producing 233U from 232Th in fusion reactor blankets. The new concept offers several advantages, including a substantial decrease in the risks of environmental pollution due to the low radioactivity of the recycled fuel. The study focuses on several scenarios for the development and use of a new fissile isotope in thermal neutron spectrum reactors (pressurized water reactors) and demonstrates the possibility of closing the fuel cycle in a system of thermal reactors with a fusion neutron source using heavy nuclei.

The article focuses on the role of radiation criteria and its evolution in the structure of arguments underlying the establishment, operation and development of nuclear energy. It demonstrates that the dominant role of radiation criteria should be reconsidered to allow broader consideration of environmental and other factors associated with sustainable development. Based on in-depth analysis of certain aspects relevant for the mutual development of nuclear energy and radiation and environmental safety requirements, the paper shows that fully-fledged regulatory and technological systems have been deployed to date to ensure the radiation safety of workers and the public: these systems cover all the tasks required to be addressed to limit the technogenic exposure under normal operation. At the same time, an unprecedented gap was noticed between the actual role of radiation factor across human health risks and its perception by the overwhelming part of society. In the near future (some hundred years), urgent tasks in the field of radiation safety will be driven, on the one hand, by the need to ensure the internal consistency of the national security system addressing health risks in general, and on the other, by global processes in the world economy associated with slow growth in energy demand, rapid reduction in the share of fossil fuels in almost all sectors of the economy among the developed countries, including transport, growing general environmental trends towards material recycling and decarbonization. The study shows what should be the attitude to radiation risks so that the nuclear energy could successfully meet the requirements arising from these trends. In this regard, the paper also provides some rational interpretation of the principle suggesting that no undue burden should be imposed on future generations.
