Brief Description: Control rod interior corrosion treatment.
The control rod interior surfaces also received a thorough treatment for corrosion. A small hole was drilled in one end of each control rod just below the end of the rod end bearing. A small squeeze bottle filled with ACF-50 was used to fill each rod about 1/4 full. The ACF-50 was then sloshed inside the control rods to coat the inside surfaces of the rods and the installed ends of the rod end bearings. The ACF-50 was then drained out and the control rods were sealed with pop rivets.
