AbstractAbstract
[en] In the report one of the main problems of nuclear energetics - preparation of isotopically enriched additions to nuclear fuel - is in consideration. At some NPP new types of fuels with integrated burning out absorber on the base of gadolinium and erbium are utilized. For compensation of the excessive reactivity neutron absorbers in the form of burning out additions are situated in fuel pellets directly. Gadolinium, erbium, hafnium, boron and dysprosium ca be used as burning out additions. The key problem in production of fuel with isotopically enriched additions is economically expedient method of enrichment

В докладе обращено внимание на одну из важных проблем ядерной энергетики - получение изотопически обогащенных присадок к ядерному топливу. На некоторых АЭС освоены новые виды топлива с интегрированным выгорающим поглотителем на основе гадолиния и эрбия. Для компенсации избыточной реактивности поглотители нейтронов в виде выгорающих присадок помещают непосредственно в топливные таблетки. В качестве выгорающих присадок могут использоваться гадолиний, эрбий, гафний, бор, диспрозий. Ключевым вопросом в производстве топлива с изотопически обогащенной присадкой является экономически целесообразный способ обогащенияOriginal Title
