Button Height Measurement Tool

For Control Rod Drive Shaft button height verification, EPI’s Button Height Measurement Tool completes the job accurately and with minimal time.

Lightweight, reliable and easy to operate, this tool can confirm button positions of a full set of control rod driveshafts (CRDS) within 20 minutes.

Typically attached to the manipulator crane hoist, the Button Height Measurement Tool is manually lifted and moved to each driveshaft without the aid of the hoist motor. The operator seats the tool on the CRDS and the tool’s inner shaft measures the button height which is indicated on the height scale.
