GE SOLUTIONS FOR NUCLEAR TURBINE ISLANDS Turbine Generator Package STEAM TURBINE: ARABELLE PLATFORM LP Exhaust with Independent Structure ARABELLE improves on the previous generation LP exhaust design with fully independent LP cylinders. By connecting the LP inner casing to an end wall rather than the LP outer casing and ultimately the turbine table, the outer casing no longer needs to act as support. This simple but powerful design innovation greatly reduces turbine load on the foundation, caused by vacuum variations or condenser forces while improving centering of both moving and...

GE SOLUTIONS FOR NUCLEAR TURBINE ISLANDS Turbine Generator Package STEAM TURBINE: ARABELLE PLATFORM

GE SOLUTIONS FOR NUCLEAR TURBINE ISLANDS Powering the World Turbine Generator Package Long Track Record of Performance and Reliability for Medium-size Nuclear Reactors The D200 turbine offers a robust architecture in which the steam first expands in a double-flow HP path. After moisture separation and reheat, it then expands in four or six LP flows. The turbine rotors, all of monoblock construction, are rigidly coupled to each other and to the generator rotor. Each rotor is supported by a pair of journal bearings. Rightful heir of the most powerful 3,000 rpm turbines with saturated steam in...
