Description

Results of the investigation into samples of glassy carbon SU-1300, SU-2000 after irradiation in the BOR-60 reactor at 360 - 400 Deg C are presented. It is established that the effect of significant radiation compression of the glassy carbon under irradiation retains till neutron fluence 3.6 x 1026 m-2 (E > 0.18 MeV). It is shown that radiation shrinkage is produced by shrinkage of graphite-like beds and decrease of molecular porosity. Increasing temperature of glassy carbon preparation from 1300 to 2000 Deg C tends to decrease of graphitization of the material under irradiation

Abstract (Russian)

Представлены результаты исследования образцов стеклоуглерода СУ-1300, СУ-2000 после облучения в реакторе БОР-60 при 360 - 400 град С. Установлено, что эффект значительного радиационного сжатия стеклоуглерода при облучении сохраняется до флюенса нейтронов 3.6 х 1026 м-2 (E > 0.18 МэВ). Показано, что радиационная усадка вызвана уплотнением пачек графитоподобных слоев и уменьшением молекулярной пористости. Повышение температуры получения стеклоуглерода с 1300 до 2000 град С приводит к уменьшению графитируемости материала под действием облучения
