Views Read Edit View history. World Nuclear Association. When any 2 of the 3 circuit paths are activated due to sensing the need for emergency reactor tripthe direct current-controlled clutches that keep each control-rod in the storage position are de-energized. This allows the reactor core to be built much more compactly, roughly half that of a CANDU of the same power. The downside was that it did not have the flexibility of fuels that the original CANDU design offered, and would no longer run on pure unenriched uranium. Retrieved 11 October The reactivity regulating and safety devices are located within the low-pressure moderator. In practice, these advantages did not work out. Namespaces Article Talk.

    However, it replaces the heavy water cooling loop with one containing conventional light water, greatly reducing costs.

    Views Read Edit View history. The Globe and Mail. The use of LEU fuel with a neutron absorbing centre element allows the reduction of coolant void reactivity coefficient to a nominally small, negative value.

    The original CANDU design used heavy water as both the neutron moderator and the coolant for the primary cooling loop.

    This design also allowed it to be refueled while it was running, improving the capacity factora key metric in overall performance.

    Archived from the original on 27 June Bruce Power considered ACR in for deployment in Western Canada, both for power generation, or for steam generation to be used in processing oil sands.

    From Wikipedia, the free encyclopedia. Neutron-absorbing rods control rods that shut down the nuclear chain reaction are stored inside isolated channels located directly above the reactor vessel calandria and are controlled via a triple-channel logic circuit.

    The use of LEU fuel with a neutron absorbing centre element allows the reduction of coolant void reactivity coefficient to a nominally small, negative value. Gadolinium nitrate Gd NO 3 3 solution, a neutron-absorbing liquid that shuts down the nuclear chain reaction, is stored inside channels that feed into horizontal nozzle assemblies.

    Further, the design used both pressurized and unpressurized sections, the latter known as a "calandria", which it was believed would lower construction costs compared to designs that used highly pressurized cores. Hidden categories: Webarchive template wayback links All articles with unsourced statements Articles with unsourced statements from January It contains seismically qualified, redundant standby generators, batteries and distribution switchgear.

    Heavy water remains in the low-pressure section of the calandria, where it is essentially static and used only as a moderator.

    Bruce Power. This was a small price to pay given the low cost of enrichment services and fuel in general. A high degree of safety system testing automation also reduces cost.

    originally calculated for the first CANDU units.
    CEO Hugh MacDiarmid is quoted as stating, "We believe very strongly that our best course of action to ensure the ACR is successful in the global market place is to focus first and foremost on establishing it here at home.

    World Nuclear Association. This design also allowed it to be refueled while it was running, improving the capacity factora key metric in overall performance. It was expected this additional cost would be offset by lower capital costs on other items, and lower operational costs. From Wikipedia, the free encyclopedia.

    FILOSOFO VOLTAIRE BIOGRAFIA RESUMEN
    The RWS can also provide emergency water via gravity-feed to the steam generators, moderator system, shield cooling system or the heat transport system of any ACR.

    All safety-related portions of the system are seismically qualified and contain redundant divisions.

    When any 2 of the 3 circuit paths are activated due to sensing the need for emergency reactor tripthe direct current-controlled clutches that keep each control-rod in the storage position are de-energized. Development of the ACR ended. Bruce Darlington Pickering Point Lepreau. Additionally, it replaces the heavy water coolant in the high-pressure section of the calandria with conventional "light" water.

    The bids required that all contingencies for time and budget overruns be considered in the plans.
