Title: SINGLE-LOOP NUCLEAR POWER PLANT WITH PRESSURIZED COOLANT
Abstract:
In a single-loop nuclear power plant with a pressurized coolant, comprising a power generating unit and a throttling device having an impeller, which are interconnected by an outlet pipe and a feed pipe, and a steam turbine connected by pipes to the throttling device and to a condenser which is also connected to the throttling steam generator, the throttling device is configured in the form of a throttling steam generator which is vertically divided into a vapour zone, a high pressure zone, and a low pressure zone by means of horizontal sealed partitions, the vapour zone is situated above the high pressure zone, which is situated above the low pressure zone, the high pressure zone is connected to the inlet of the feed pipe and is connected to the low pressure zone by throttling nozzles provided in the partition between said zones, about the periphery of said partition and at an angle to the vertical, and the low pressure zone is connected to the vapour zone by a vertical pipe which passes through the centres of the horizontal sealed partitions and the high pressure zone, wherein the single-loop nuclear power plant is additionally provided with an electric motor configured for rotation of the impeller. The single-loop nuclear power plant with a pressurized coolant and a throttling steam generator allows highly efficient use of nuclear fuel, and also provides reliable and safe operation in all regimes, and is applicable in the nuclear power industry.
