Electromagnetic safety device for the suspension of the rods in a nuclear reactor
A coupling is provided for holding and releasing a safety and a safety-and-control rod in a nuclear reactor which coupling comprises three pairs of electromagnets, said electromagnets being arranged in a circular row and act upon a single armature attached to the rod; the electromagnets of each pair being disposed at diametrically opposed position with respect to the rod axis. The signal from each sensor of a set of multiple sensors of each relevant parameter of the reactor operation is supplied to a meter of the parameter. The signals from one of each set of meters are conjointly supplied to a logic circuit which is connected to an amplifier. Finally the power from each amplifier is separately supplied to each pair of electromagnets for controlling the hold and release of the rod. The electromagnets of the coupling are arranged in a circular row and act upon a single armature attached to the rod. 2 claims, 7 drawing figures.
