Abstract
PURPOSE: To shorten a length of time for the rotor of a turbine to pass its critical speed of rotation without causing an emission of a radioactive material in a condenser, by providing injection nozzles in a part of exhaust port at the side of blade final stage in the low pressure steam turbine of a boiling water nuclear power plant.
CONSTITUTION: Under a low pressure turbine 3 in a boiling water nuclear power generating plant, a condenser 4 is installed. In an exhaust port 17, even-numbered spray nozzles 21 are provided at the position horizontal and symmetrical with a rotary shaft 13. When the steam turbine is stopped, the flow of its steam is stopped from a feed port 16 to decrease its rotational speed. When the turbine reaches the range of its critical speed of rotation, a flow regulator valve 23 is opened to feed steam from a boiler 22 in the station. In this way, because of a shorter time for passing the critical speed, an emission of radioactive material in the condenser 4 can be prevented.
