dc.description.abstract© 2019 Published under licence by IOP Publishing Ltd.We consider the problem of realization of the residual energy resource of fuel during decommissioning of the High-Power Channel-Type reactor. A mathematical model of the fuel assemblies spectrum for energy production is provided. Two methods of reactor decommissioning are compared. The first possible way to preserve the criticality of the reactor during decommission is the collapse of the core, when fuel assemblies with high energy production are discharged. The second possible way of decommissioning is formation of a two-zone loading: Fresh fuel assemblies are put in the centre, burnt out-on the periphery. It is shown that the second method gives a greater gain in power and unprocessed energy resources. The results are obtained on the point model of the fuel assemblies spectrum dynamics in the linear approximation of the with linear dependences of the power and the multiplication factor of FAs from energy productionn and indicate only the possibility of optimizing the fuel use in the process of removing the RBMK from service.
