The results of experimental and computational investigations of microfuel behavior under the action of neutron pulses in the BIGR reactor are presented. The methods used in the present work made it possible to determine the change in the structure of the irradiated samples, specifically, to record interlayer gap formation in the microfuel and the actual fracture of the microfuel. The results of this work could be helpful for evaluating the service life of microfuel and the consequences of emergency situations in HTGR as well as for developing and perfecting the corresponding computational software.
