These studies and their findings related to problems isotope solutions, thermodynamics of geochemical prcesses ore formation, isotopic exchange in the biosphere, atmosphere, out space,with the problems of nuclear energy and the environment. In the study of thermodynamics isotope exchange for obtaining data on the conditions of the Earth's crust and hydrosphere gained such strong fundamental and practical results. Heavy isotopes of elements (hydrogen, oxygen, carbon, uranium) more active thermodynamically than lighter isotopes, and enrich the material with increasing temperature, conlitions of acidity a oxidation of water solutions that traced at fractionation of isotopes of uranium and light elements in the deep areas of the crust, hydrosphere, living organisms, comets. Free oxygen in Earth's atmosphere and comets formed with hydrochloric acid in the reaction of chlorine gas(g) with liquid woter (l): Cl2(g) + H2O(l) = 2HCl(l) + 0,5O2(g). Thus at the top arhaea creted by the magmatic acidic ocean of salt chlorides (solution of NaCl), and in Proterozoic - gold and uranium deposits at penetration in granite crast acidic water from gold and uranium where the restored conditions and formed pitchblende-albite mineralization. Only in Riphean (from 1,65 billion. years ago) the activities of plate tectonics emerged first land and the first marine sediments - sand, clay and carbonate in the neutralization of sea water. With Riphean especially fantroznoy increases the activity of plate tectonics, volcanism, seismic activity, the number of marine sedementery rocks, as well as hurricanes, earthquakes and technogenic negative impact on the environment. Photosynthesis is not an efficient source of free oxygen because fotobakteriyi and plants combine anaerobic and aerobic steps and simple aerobic later emerged only in the Phanerozoic. Developed technology for nuclear enrichment of uranium concentrate isotope 235U isotope fractionation under reducing conditions in aqueoukas solutions. In sediments obtained pitchblende content in 235U isotope uranium solution is 2,0-2,5%. According to the experiments of living organisms rid of toxic heavy isotopes for them when acquiring energy in the active oxidation of carbohydrates and removal of products such as water and carbon dioxide from the body, which in general restoration conditions prevail and light isotopes. In view of the rapid increase of mankind (world population doubling every 40-50 years) for its energy needs and the environment, we must quicly develop nuclear energy, which is the most durable and ecological. In cities especially important to transfer road transport on electricity and hydrogen. In the Chernobyl zone evacuation is particularly dangerous contamination of the environment before a very moving radioactive isotope 90Sr, which in filtering groundwater with radioactiv waste gets fourth bloc in the district. Pripyat river and the Kiev Sea. Requires complete isolation of radioactive waste. Results of research findings about NDR quite widely mentioned in the scientific literature, reported at scientific and practical conferences, congresses, meetings, seminars.
