Operation of a nuclear power plant on an integrated electric system

A nuclear power plant of the pressurized water-moderated and water-cooled type is able to meet the requirements of a central station facility for load changes and for picking up load. It may be used for system load control the same as for conventional plants. The negative temperature coefficient of reactivity characteristic adjusts reactor power level to meet power changes of the steam plant, and provides plant stability. The automatic temperature control system adjusts the control rods to compensate for reactivity changes in the reactor caused by fission products.
