Abstract
A remote gaging apparatus for remotely measuring the pellet stack length and plenum length within a nuclear reactor fuel element comprises a housing capable of having a nuclear fuel element inserted therein with a drive mechanism disposed in the housing and attached to a rod having a stop mounted on the rod for selectively inserting the rod into an open end of the nuclear fuel element. The remote gaging apparatus further comprises a measuring device disposed in the housing and associated with the stop for contacting the stop when the rod is inserted into the fuel element thereby measuring the length of insertion of the rod in the fuel element. By determining the length of insertion of the rod in the fuel element, the stack length of nuclear fuel pellets in the fuel element can be determined along with the length of the unfilled plenum of the nuclear fuel element.
