Peach Bottom Atomic Power Station replaced their admiralty brass condenser

tubes with modules of titanium tubes in the early 1990s.

        Dresden Station is currently planning a power uprate project, which

will

        include modifications to our condensers.  The current plan is to

place

        stakes in between the condenser tubes to provide additional bracing.





        As an alternative, an engineer at the station is looking at the

possibility

        of a full-scale replacement of the condenser tubes (that's 60,000

tubes per

        condenser).  He has asked that I pose a question to the listserve in

the

        hopes that someone out there may have experience with a similar

evolution

        with a BWR.



        Any comments/suggestions should be forwarded to Pete Scardigno at
