Abstract
A lattice high bar for a nuclear steam generator tube support bar array has scalloped indentations along its length. The scalloped indentations are located at points on the high bar where water tubes will contact the high bar. The indentations extend from one edge of the high bar to about two-thirds of the distance across the bar. When the high bars are used in a lattice bar array, only the unscalloped portion of the high bar contacts an adjacent supported tube, thereby reducing the contact area and the likelihood of corrosion and cracking and also reducing the length over which inspection is impeded. Additionally, the flow path created by opposed but overlapping scallops at the 120° intersections at certain points along the high bars improves the flow sweeping over the surface of the supported tube.
