THERMO-HYDRAULIC AND DYNAMIC CHARACTERISTICS OF A MOISTURE SEPARATOR HEATER FOR NUCLEAR POWER PLANTS
The moisture separator heater (MSH) for a 1100 MWe reheating IMR plant was developed. The MSH removes moisture from the high pressure turbine exhaust steam and then superheats this steam using the high pressure turbine extraction steam and part of the main steam from the reactor. The following items were studied forthe development of the MSH.1)Experimental and numerical analyses of thermo-hydraulic characteristics for the MSH. 2)Stabilization of two phase condensate flow inside tubes.3) Vibration of the tube bundles. 4) Computer simulations for dynamic characteristics.5) Control method of the MSH.
