ABSTRACT:
A flux mapping system for a nuclear reactor uses a detector having an outer diameter approximately fifteen percent smaller than the inner diameter of distribution tubing through which it passes and a length less than eight percent of the minimum bend radius of the tubing. Frictionless limit switches are used in the flux mapping system to further reduce friction against cables which drive the detectors through the distribution tubing. In combination, these dimensions and switch changes result in a fifty percent improvement in driving force at the thimbles into the core of the nuclear reactor.
