The neutron flux monitoring system consists of two startup channels, two control channels and four safety channels. Typically, the safety channels are provided to monitor the ex-core neutron flux over the range of source power to full power of the nuclear reactor. Two startup channels provide source level range neutron flux information to a reactor operator. Two control channels provide neutron flux information, in the power operating range, to the reactor regulating system during automatic turbine load-following operations.  1, record 1, English, - startup%20channel

Contrôle de la puissance neutronique. Des détecteurs classiques de mesure de puissance neutronique sont placés, en général en dehors de la cuve principale, sauf quelques fois pour des chaînes de démarrage, dans une position où ils peuvent contrôler le fonctionnement du réacteur sur toute sa gamme de puissances.  1, record 1, French, - cha%C3%AEne%20de%20d%C3%A9marrage

CANDU plants can be operated in two basic modes :reactor-following-turbine(RFT) and turbine-following-reactor(TFR). Steam generator pressure control plays a pivotal role in these schemes. In TFR mode the reactor power is held constant at a level set by the operator and the turbine governor control valves are used to regulate steam pressure. This mode is suitable for unit operation within a large system network where it is used to supply the base loads while other units are used to supply peak loads. Since reactor conditions remain constant, this mode also constitutes a safer state of operation from the nuclear plant perspective. The control system reverts to this mode of operation during plant upsets. In RFT mode, the turbine load is set by the operator and the reactor is used to regulate steam pressure. In both TFR and RFT modes, the turbine is also used to regulate speed and assist the system in meeting short-term changes in electrical load demand. In RFT mode, the governor control valves also attempt to maintain a constant generator output.  1, record 2, English, - turbine%2Dfollowing%2Dreactor

Turbine suivant le réacteur. Dans ce mode de commande, les charges de la centrale doivent suivre le rendement du réacteur. Pour cela, le programme de commande de la pression des générateurs de vapeur règle les charges de la centrale pour maintenir la pression des générateurs de vapeur à un niveau constant. Ce mode est utilisé à de faibles niveaux de puissance du réacteur lors du démarrage, de l’arrêt ou lorsque la pression des générateurs de vapeur est insensible à la puissance du réacteur. On l’utilise également dans des conditions extrêmes lorsqu’il n’est pas souhaitable de modifier la puissance du réacteur.  1, record 2, French, - turbine%20suivant%20le%20r%C3%A9acteur

In my time as a Nuclear Operator at the Pickering Nuclear Generating Station, I spent approximately three years as a Supervised Control Panel Operator. This job involved, among other duties, the performance of a large variety of tests on the reactor components and instrumentation. Communication and leadership skills were of paramount importance to the execution of these tests. Each test involved the coordinated activities of up to ten operators, mechanics and control technicians, with the lead role assumed by myself. I had to ensure that each person involved in the test understood their role precisely and was prepared to follow my orders. Some of the more sensitive tests could have had adverse consequences for both reactor systems and for personnel safety, so it was essential that my communication skills and leadership abilities be well developed.  3, record 3, English, - supervised%20control%20panel%20operator

Présentement, les titulaires de permis de centrales à tranches multiples exigent qu'un OSC [opérateur de salle de commande] ou un adjoint à l'opérateur de salle de commande (AOSC) soit présent aux panneaux de la salle de commande principale en tout temps. Les AOSC sont qualifiés pour faire la surveillance de panneaux d'une tranche mais ils doivent être sous la supervision d'un OSC.  1, record 3, French, - adjoint%20%C3%A0%20l%27op%C3%A9rateur%20de%20la%20salle%20de%20commande
