The CANDU designs have several emergency cooling systems, as well as having limited self-pumping capability through thermal means (the steam generator is well above the reactor). Even in the event of a catastrophic accident and core meltdown , the fuel is not critical in light water. [ 8 ]
The inverted U-tube bundle of a Combustion Engineering steam generator. A steam generator (aka nuclear steam raising plant ('NSRP')) is a heat exchanger used to convert water into steam from heat produced in a nuclear reactor core. It is used in pressurized water reactors (PWRs), between the primary and secondary coolant loops.
In 2007, Team CANDU, a consortium of Atomic Energy of Canada Limited, Babcock & Wilcox Canada, GE-Hitachi Nuclear Energy Canada Inc., Hitachi Canada Ltd and SNC-Lavalin Nuclear Limited [6] began a $2.5 million feasibility study regarding the installation of a new 1,100 MWe Advanced CANDU Reactor at Point Lepreau, to supply power to New England ...
The power plant comprises eight CANDU pressurized heavy-water reactors arranged into two plants (A and B) with four reactors each. Each reactor stands within a reinforced concrete containment. The steam generators are 12 m tall, and weigh 100 tonnes each.
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. Emergency power supply system (EPS): The EPS system is designed to provide each ACR unit with the required electrical power needed to perform all safety functions under both ...
Pickering Nuclear Generating Station is a Canadian nuclear power station located on the north shore of Lake Ontario in Pickering, Ontario.It is one of the oldest nuclear power stations in the world and Canada's third-largest, with eight CANDU reactors.
The first CANDU was a demonstration unit, the Nuclear Power Demonstrator (NPD). In 1958, before NPD was complete, AECL formed the Nuclear Power Plant Division at Ontario Hydro’s A.W. Manby Service Centre in Toronto to manage the construction of a full-scale prototype for future CANDU commercial power plants. Ontario Hydro would operate the ...
The Darlington reactors have been among the best performing in OPG's CANDU fleet, including a top year in 2008 in which the plant achieved a combined 94.5% capacity factor. [28] In June 2016, the World Association of Nuclear Operators (WANO) named Darlington one of the safest and top-performing nuclear stations in the world - for the third time ...
