Generation of flammable gases in water received little attention for the dispersion fuel of complex composition. The study aimed to obtain experimental data on the flammable gas generation rate to justify fire and explosion safety in handling the dispersion spent fuel underwater. The paper describes the results of the experiments investigating the accumulation of flammable gases. It also addresses the assessments of radiolytic hydrogen produced during underwater storage of damaged spent nuclear fuel.
