A feature of these fuel cycles is the small neutron leakage due to the location of fresh nuclear fuel in the internal cells of the a.z. VVER-1000 reactor.In the process of doing the work, it is necessary to determine the type of fuel, namely, the possibility of optimal choice of radial enrichment of fuel and burnable absorbers, which allow for the maximum possible duration of the stationary fuel cycle and minimal neutron leakage beyond the limits of a.z.to obtain the minimum possible uneven distribution of energy release in the volume a.z.When optimizing the parameters of the fuel, the maximum reduction of the radiation load on the IVD and the reactor vessel and fuel efficiency are also estimated by reducing the cost of uranium per unit of electricity generated. popup.nrat_date 2024-12-10 Close
