We are now back to the revisions to the weir and constraining the annular space between the surface of the condenser tubes and the interior diameter of the weir.  Please find uploaded a drawing with Revision 2 for the changes to the weir and condenser head assembly.  I understand the concern of the leakage of the tubes, but if the tubes leak the option is to grind the weld and repair the leak.  In reviewing competiters internal layouts, there seems to be an industry design, based on the two competitiers units I have seen, that the annular gap is minimized.  I would like to request we discuss this point in a telecon Monday, 20 August at 6:00pm your time.  Please use the following phone number.
