... C70600) was selected for retubing. The 70Cu-30Ni tubes in the air-removal section were not replaced. This failure could have been avoided by following the nuclear plant layup procedures, which included flushing, draining, and maintaining a dry environment. Both lots of tubing were visually examined...

..., Alloy 194, and aluminum bronze. As a result, the use of 90Cu-10Ni (B111-Alloy C70600) is recommended for the replacement tubes. In addition to switching to a more corrosion-resistant alloy, extreme care should be taken in the manufacturing of the replacement tube bundles to avoid imparting any...
