   After following the Vigil TV series (with all its   
   reported errors) and also the prog on HMS Trenchard,   
   when a Brit U-boat is powered by nuclear fuels, how   
   do they condense the steam?   
      
   With sea water? If so, there must be difficulties   
   in sealing the intakes and outfalls from deep sea   
   pressures.   
      
   Perhaps the steam is heated to 200C and only cools to   
   100C through the turbines before recirculating   
   so no condensing is   
   required. This, of course, will be wasteful   
   of some thermodynamic energy, but there's so much   
   in reserve in the nuclear fual that perhaps it does not   
   matter.
