Load detent points of loads in nuclear power plants

When transporting loads, a detachable connection exists between the load and the hoisting device. While the load pickup and carrying means are within the lines of force and therefore subject to the KTA rules 3902 'Design of hoisting devices in nuclear power plants' and 3902 'Inspection and operation of hoisting devices in nuclear power plants', these rules cannot, or not directly, be applied to the load detent points. Technically, load detent points do not form part of the hoisting device. Therefore it is useful to work out an independent rule for load detent points, which stipulates the design and inspection requirements for screw-fastened, casted, welded and concrete-anchored load detent points. The safety related concept on which this rules is based proceeds from the fact that in particular by design and materials selection for load detent points the same safety is achieved as for the hoisting device.
