Description
Regularities of void formation are considered for the ''secondary'' irradiation-induced swelling of structural carbon materials. This swelling is observed after pre-shrinkage of materials under neutron irradiation. It is assumed that two processes are resulted in the secondary swelling. One is the increase in void volume in a crystal up to its saturation. The other is the transformation of these voids into macrovoids (microcracking). At irradiation temperatures of 1200 to 1300 deg C the void formation is minimized for graphites with 150 < Lsub(c) < 300A, where Lsub(c) is grain size
