Sistema de instrumentación interna de un reactor nuclear con tarjeta electrónica evolucionada y procedimiento correspondiente de modificación de un sistema de instrumentación interna de un reactor nuclear |
摘要 |
This internal instrumentation system (3) for a nuclear reactor comprises at least: a probe (7) for measuring the neutron flux in the core (5) of the nuclear reactor; a displacement cable (9) for moving the probe inside the core (5); a rotary drive device (35) for the displacement cable (9); and a determination device (44) for determining the angular position of the rotary drive device (35), which determination device comprises a synchrotransmitter (45) which itself comprises a rotor made to rotate as one with the drive device (35) and a stator having three windings. The device (44) for determining the angular position comprises an electronic unit for digitising at least two of the voltages at the terminals of the stator windings of the synchrotransmitter and for digitally processing these digitised voltages in order to produce at least one output signal representative of the angular position of the rotary drive device (35). |
