Abstract
A weighing tool and method for determining the weight of ice contained within each of a plurality of ice baskets received within corresponding compartments of a lattice frame, as employed with nuclear power generators. A cylinder body includes lug support frames and corresponding lugs movable to retracted positions for inserting the weighing tool within the upper end of an ice basket, and to extended positions for being engaging in the ice basket and securing the tool thereto. A piston movable in sliding relationship within the body and defining upper and lower compartment therein is secured through a piston rod to a support bar which rests on the lattice frame and spans the compartment. Hydraulic fluid under controlled, increasing pressure is introduced into the upper compartment, driving the cylinder body upwardly relatively to the stationary piston so as to raise the ice basket. The pressure necessary to lift the ice basket provides a measure of the total weight of the ice basket. Alternatively or additionally, a load cell subjected to the weight of the raised ice basket provides an output indication of the weight. Since the weight of the empty ice basket is known, a simple subtraction yields the weight of ice resident within the ice basket.
