Hardin, Jr, R T; Marshall, J R

In a nuclear fuel transfer system which includes a cart having a pivotably mounted fuel container which is movable between a horizontal position and an upended position, guide means for guiding the cart along a path which leads to a floodable fuel transfer station, and upender means at the fuel transfer station for engaging the container when the cart is at a predetermined position and for selectively moving the container between the horizontal and vertical positions, a position sensing mechanism is described comprising: a feeler mechanism disposed at the transfer station at a position to engage the cart, the feeler mechanism being movable between a first position and a second position when the cart is not located at the predetermined position; an anchor element operatively connected to the upender means; an electrical position sensor mounted at a dry location above the transfer station; and means for transferring mechanical motion of the feeler mechanism and the anchor element to the position sensor.
