Description
HV RP nuclear is a series of special high-voltage motors from the Special Motors series for nuclear power, intended for driving the primary (reactor) cooling circuit pumps of nuclear power plants. The motors are vertical asynchronous, with or without a flywheel. The flywheel increases the moment of inertia of the unit and provides smooth run-down of the pump in the event of a power loss, which keeps the coolant circulating through the reactor core during the transition to emergency cooling. The motors are designed to the most stringent requirements of the nuclear industry and provide reliable operation in a strictly regulated environment; the manufacturer notes many years of experience in supplying motors, drives and generators for critical nuclear applications, and lifecycle support. Motor power is 4.5–12 MW, rotational speed 1200–1800 rpm, rated voltage up to 13.8 kV, 4–6 poles, and the operating mode is direct-on-line start from the grid (DOL). The 50 Hz version corresponds to a speed of about 1500 rpm (4 poles), and for 60 Hz it is 1200 or 1800 rpm. Detailed characteristics (insulation system, cooling, seismic resistance, qualification under nuclear industry standards) are not given on the pages reviewed and are provided for a specific project. Applications are main circulation pumps of reactor systems, in particular during the modernization of operating power units.
