1.2 Discussion This procedure provides instructions to remove, clean, inspect, install, and test the heat exchanger tubes.
hpically, heat exchanger tubes that are plugged and those tubes which have failed eddy current testing are replaced.
l This procedure also involves performing a boroscopic visual examination of TBSCCW heat exchanger internals, tube support baffles, impingement plate, and tubesheet ends.

I 7.1 Revision 1 incorporates the following modifications:
Deleted requirement to remove tubes from from the outlet side-of heat exchanger. Reworded instructions so the tubes can be l
removed from either end.
Changed depth of roll in tubesheet to concur with Engineering direction regarding as-found thickness of tubesheet.
}
Changed desired tube vall reduction value from 8 to 12 % to 4 to
=
6%.
Added prerequisite that mechanics perform familiarization for tube cutting, removal, handling, and rolling.
AdJed requirement to clean tube after cutting and prior to
=
removal.
i Add size and type of replat ement tube material.
Added caution to not expand the tube beyond the tubesheet.
=
O 1
Changed internal tube cutter to type that does not leave a cut i
ring.
