  • Nuclear reactor rod control mechanism control system
    Publication number: 20090116605
    Abstract: The control system comprises an independent removable power module for each coil of a rod control mechanism equipped with three operating coils supplied from a three-phase current source. The power module is connected in series with the corresponding coil and comprises a rectifier circuit with three thyristors controlled in phase angle by a corresponding regulation circuit according to setpoint current values associated with the coil. A monitoring circuit connected to a display interface displays the current flowing in the coil associated with the power module. In the event of a fault, the module and coil involved are easily detected and replaced without requiring shutdown of the whole of the reactor.

  • Device for determining the primary current of a current transformer comprising saturation correction means
    Patent number: 6611136
    Abstract: The device comprises modelling means representative of an inverse model of the current transformer. These modelling means receive on input the instantaneous values of the secondary current measured in a first secondary winding of the current transformer and, by means of an integrator, the integral of the secondary voltage measured at the terminals of a secondary winding of the current transformer. The modelling means supply on output the instantaneous values of the associated primary current, corrected in case of saturation of the transformer. The secondary voltage can be supplied by the first secondary winding or by an additional second secondary winding, arranged around the first one.
