Abstrakt: The results of an investigation of SU-1300 and SU-2000 glassy carbon samples after irradiation in a BOR-60 reactor at 360–400°C are presented. It is established that substantial radiation compression of glassy carbon under irradiation remains up to neutron fluence 3.6·1026 m–2 ( E > 0.18 MeV). It is shown that radiation shrinkage is caused by compaction of packets of graphite-like layers and decrease of molecular porosity. Increasing the production temperature of glassy carbon from 1300 to 2000°C decreases the graphitizability of the material under irradiation. [ABSTRACT FROM AUTHOR]
