ABSTRACT:
An apparatus for monitoring the position of the shaft of a coolant circulating pump of a nuclear steam generating system comprising light source for directing a light beam at a number of reflecting surfaces on the shaft and a pair of spaced apart light receiving devices adapted to receive light beams reflected off the reflecting surface. Light from the receiving devices is conveyed, by fiber optic cables, to intensity measuring devices which measure the intensity of the two light beams on a time-dependent basis. A processor calculates the shaft rotational speed and the magnitude of the shaft wobble as functions of the time-dependent intensity measurements of the pair of reflected light beams.
