Abstract: A machine for examining a nuclear reactor fuel assembly, having a flooring of elongated shape, a rotary container located on a support at one end of the flooring, two vertically arranged rigid structures each consisting of two parallel tubes, a latching mechanism for the fuel assembly, including a large and a small branch which are pivotable with respect to each other, a device for immobilizing the small branch relative to the large branch, a trolley that can be displaced along the flooring towards and away from the support and carries a vertical column along which a bracket with a carriage is movable on which a television system or the like for examining the fuel assembly may be mounted.

Abstract: A device for the remote checking of the characteristic of a spring includes a system of known masses or weights displaceable in translation in a vertical direction, each of the masses forming said system being vertically displaceable within certain limits with respect to the other masses in such a way that, upon lowering them, their weights are successively supported by the spring and are consequently summated. A dynamometer determines the moment when, during the descent of the system, a given mass rests on the spring. The device then measures the deflection of the spring by measuring the displacement of the mass resting on the spring relative to a reference point fixed with respect to the spring.
