ABSTRACT:
The rod position indicator system of a pressurized nuclear reactor can be calibrated for one or more control rods without shutdown of the reactor. The procedure involves lowering reactor power to a level at which the control rod which appears to be misaligned can be fully inserted and its rod position indicator calibrated.
