Methods and programs for optimal control of power distribution in RBMK

Programs used for optimal control of power distribution in the RBMK by changing the submerged lenmgth of the reactor control system rods are reviewed. Different modifications of the linear programming method and iteration methods of step searching for the extremum are used for problem solving. The programs are intended for preliminary correction of physical calculation data employed as a source information in the centralized control systems, for systematic problem solving, for NPP operating personnel assistance in reactor control as well as for calculational model construction in planning partial and continuous fuel recharging
