AAround throttle valve stems
BAt the inner stage diaphragms
CAt the steam strainer inlet
DAfter the last stage of the ahead rotor blading
AI Explanation
The correct answer is D) After the last stage of the ahead rotor blading. Moisture shields are located at the last stage of the ahead rotor blading in a main propulsion steam turbine. This is to prevent water droplets from impinging on the turbine blades and causing erosion or damage. The moisture shields help to separate and remove any condensed steam before it reaches the final turbine stage, ensuring the turbine operates efficiently and safely. The other answer choices are incorrect because they do not represent the proper location of the moisture shields within the steam turbine system.
