Description

An analysis of corrosion processes is accomplished which proceed in a fuel element can of EhP823 ferritic-martensitic steel with a lead sublayer under neutron irradiation in BOR-60 reactor. Threshold values of oxygen content in lead are calculated. Corrosion behavior of steel constituents under reactor operation conditions is considered. Test results are given for fuel can material at 700 deg C under various conditions: with and without UN fuel, in unalloyed lead and in lead doped with steel alloying elements. Methods of corrosion protection are proposed for fuel can inner surface

Abstract (Russian)

Проведен анализ коррозионных процессов в оболочке тепловыделяющего элемента из ферритно-мартенситной стали ЭП823 с подслоем из свинца, протекающих при воздействии нейтронного облучения в реакторе БОР-60. Рассчитаны пороговые значения содержания кислорода в свинце. Рассмотрено коррозионное поведение компонентов стали в условиях работы реактора. Приведены результаты испытаний материала оболочки твэла при 700 град С в различных условиях: при наличии и отсутствии UN топлива, в чистом и легированном компонентами стали свинце. Предложены методы защиты внутренней поверхности оболочки твэла от коррозии
