[en] The biggest part of delayed neutrons is produced during decay processes of isotopes belonging to the 2, 3 and 4 neutron classification group during reactor operation. The most powerful delayed neutron emitters are isotopes of bromine (24%), iodine (21%), barium (15%) and rubidium (14%) for the 16 MWd/kg fuel burn-up of RBMK-1500 reactor. The relative influence of bromine and iodine isotopes increases with a time after reactor stopping. The emission of delayed neutrons decreases with fuel burn-up and for the 18 MWd/kg burn-up is 1.2 times smaller. (author)
