Abstract

1. Топливная композиция для водоохлаждаемых реакторов АЭС на тепловых нейтронах, включающая смесь регенерированного плутония и обогащенного урана в виде оксидов, отличающаяся тем, что в качестве обогащенного урана используется обогащенный регенерированный уран или его смесь с обогащенным природным ураном, при соотношении компонентов, определяемом энергетическим потенциалом, равным потенциалу свежеприготовленного топлива АЭС из обогащенного природного урана, обеспечивающим 100% загрузку активной зоны реактора.2. Композиция по п.1, отличающаяся тем, что она содержит регенерированный плутоний и часть регенерированного совместно с ним урана без обогащения.3. Композиция по п.1 или 2, отличающаяся тем, что она содержит уран и плутоний, регенерированные в разное время, в том числе из ОЯТ реакторов разных типов и/или партий, и смешанные по расчету в любом сочетании для достижения требуемого энергетического потенциала.4. Композиция по п.3, отличающаяся тем, что смесь регенерированных плутония и обогащенного урана содержит меньшую часть последнего в виде обогащенного природного урана.5. Композиция по п.3, отличающаяся тем, что смесь регенерированного плутония и обогащенного урана содержит регенерированный уран с повышенным стартовым обогащением.1. Fuel composition for water-cooled reactors of nuclear power plants on thermal neutrons, including a mixture of regenerated plutonium and enriched uranium in the form of oxides, characterized in that enriched regenerated uranium or its mixture with enriched natural uranium is used as enriched uranium, with the ratio of components determined by the energy potential equal to the potential of freshly prepared NPP fuel from enriched natural uranium, providing 100% loading of the reactor core. 2. Composition according to claim 1, characterized in that it contains regenerated plutonium and a part of uranium regenerated together with it without enrichment. Composition according to claim 1 or 2, characterized in that it contains uranium and plutonium, regenerated at different times, including from spent nuclear fuel from reactors of different types and / or lots, and mixed according to the calculation in any combination to achieve the required energy potential. ... The composition according to claim 3, characterized in that the mixture of regenerated plutonium and enriched uranium contains a smaller part of the latter in the form of enriched natural uranium. The composition according to claim 3, wherein the mixture of regenerated plutonium and enriched uranium contains regenerated uranium with increased initial enrichment.
