Twin-rotor combined turbine drive with a transmission for the nuclear power plant equipment emergency water supply system

摘要

Considered is the original constructive version of pump unit’s combined turbine drive, the suggested solution being to fix impellers at different shafts interconnected with a transmission mechanism. The study goal was to analyze the possibilities of developing a device model, which can be applied as a turbine drive, with the use of wet non-separated steam as a working body. The considered design relates to power engineering industry and can be used as a feeding pump drive supplying the aquatic environment (heat carrier, working fluid) in the circulating loop of nuclear power plants at pre-emergency and emergency operation modes.
