The VVER-1000 (B320) reactor models were developed for the Montecarlo MCNPX code. The paper analyzes the design features of "gray" absorbing rods of the control and protection system (CPS) for the implementation of load-following modes of PWR reactors. The technical aspects of load following for PWR NPPs, which have been gradually implemented in the European Union energy sector, as well as the current requirements of utilities for unit maneuverability, are presented. The features of the gray cluster assemblies of the Westinghouse AP1000 reactor, advanced neutron-absorbing materials and structures of fuel rods, and the maneuvering mode are analyzed. advanced neutron-absorbing materials and fuel assemblies, and the maneuvering mode of power control. Modeling of the shunting mode of power control was carried out. of VVER-1000 reactor power, the results of which show that when using gray transients occur with smaller fluctuations in the AO.
