Description

Mass part of 235U in basic water flows and water aggregates of the Ukrytie object is determined by mass spectrometry. It is shown that there are at least two water flows in which isotope ratios 235U/238U exceeds significantly the ratio of these isotopes in average fuel of the 4-th block. Possible mechanism of formation of fuel aggregations with burnup deep lower than mean values inside the Ukrytie object is discussed

Abstract (Russian)

Методом масс-спектрометрии определена массовая доля 235U в основных водопотоках и водных скоплениях объекта Укрытие. Показано, что существует по крайней мере два водопотока, в которых изотопные отношения 235U/238U существенно превышают отношение этих изотопов в среднем топливе 4-го блока. Обсужден возможный механизм образования внутри объекта Укрытие скоплений топлива с глубиной выгорания ниже среднего
