SUPPORT ASSEMBLY FOR USE WITH A NUCLEAR REACTOR TOOL ASSEMBLY

摘要

A support assembly for controlling deflection of a cantileverable shaft portion in a nuclear reactor tool assembly has at least one pair of leverage members for coupling with the shaft. The members extending radially away from the shaft and are axially spaced apart and secured to an outer surface of the shaft at radially inward portions of the leverage members. A bending moment actuator extends between outward portions of the members for applying force therebetween for displacing the outward portions relative each other for applying moment to the shaft extending between the radially inward portions, the moment rigidly controlling deflection of the shaft when it is cantilevered. The assembly may be coupled with the outer surface of the shaft in mutually independent short intervals of bending moment actuators and corresponding leverage members. The assembly may be coupled with an inner surface of a hollow shaft.
