Description

An improved method of nondestructive assay of the gamma spectra, obtained after repeated neutron irradiation of the spent fuel assemblies of the IRT-3M reactor is described. The gamma spectra obtained permit to observe and estimate the 236U, 237Np and 238U content in the spent fuel assemblies. Possibilities of the developed method are described

Abstract (Russian)

Описывается усовершенствованный метод неразрушающего анализа гамма-спектров, полученных после повторного нейтронного облучения отработавших ТВС реактора ИРТ-3М. Полученные гамма-спектры позволяют наблюдать и оценить содержание 236U, 237Np и 238U в отработавших ТВС. Описываются возможности разработанного метода
