nuclear generating station![click to hear](/images/speaker.jpg)
Plant that produces electricity from thermal energy generated by the fission of fuel atoms in a reactor.
high-pressure steam inlet ![click to hear](/images/speaker.jpg)
Steam from the steam generators is carried to the first section of the turbine; here, it cools down and loses some of its energy.
separator ![click to hear](/images/speaker.jpg)
Device that removes any water from the steam to prevent damage to the turbine’s runner.
turbine stop valve ![click to hear](/images/speaker.jpg)
Device that blocks steam from entering the turbine.
reheater ![click to hear](/images/speaker.jpg)
Device used to increase the temperature of the steam from the first section of the turbine to reinject it into the second section.
condenser water outlet ![click to hear](/images/speaker.jpg)
Water in the condenser returns to its original source.
low-pressure steam inlet ![click to hear](/images/speaker.jpg)
Heated steam is reinjected into the turbine, where it releases its remaining energy.
condenser ![click to hear](/images/speaker.jpg)
Water collected from the water table flows in a circuit to cool the steam from the turbine and condense it into water.
turbine ![click to hear](/images/speaker.jpg)
Machine in two sections whose steam-activated runner transmits mechanical energy to the rotor shaft of the generator.
generator ![click to hear](/images/speaker.jpg)
Turbine-powered rotating machine that converts mechanical energy into electric energy to direct it toward a transmission network.
turbine building ![click to hear](/images/speaker.jpg)
Enclosure housing the devices (turbines and generator) used to produce electricity.
spent fuel discharge bay ![click to hear](/images/speaker.jpg)
Water-filled basin that receives spent fuel as it exits the accept machine; the water acts as a protective barrier against the radiation emitted by the fuel.
reactor building airlock ![click to hear](/images/speaker.jpg)
Secure area where equipment and personnel can pass safely through the reactor building.
dousing water valve ![click to hear](/images/speaker.jpg)
Device that releases water from the dousing water tank in the reactor building to condense the radioactive steam.
steam generator ![click to hear](/images/speaker.jpg)
Apparatus that turns water into steam, which in turn activates the turbine.
dousing water tank ![click to hear](/images/speaker.jpg)
Vat that contains water to cool the radioactive steam in the reactor in the event of an accident; this prevents a rise in pressure.
reactor building ![click to hear](/images/speaker.jpg)
Concrete structure surrounding the reactor vessel; it is a protective barrier against radioactivity.
steam generator room cooler ![click to hear](/images/speaker.jpg)
Cooling system that controls the temperature of the room housing the generators.
deuterium oxide upgrading ![click to hear](/images/speaker.jpg)
In power stations where heavy water is used as a moderator, a filter holds back steam (deuterium oxide) at the mouth of the stack.
heat transport pump ![click to hear](/images/speaker.jpg)
Apparatus that circulates the coolant fluid between the reactor and the steam generator.
reactor ![click to hear](/images/speaker.jpg)
Tightly sealed area where fission of the fuel is carried out in a controlled manner to release heat.
calandria ![click to hear](/images/speaker.jpg)
Safety containment wall that separates the reactor from the rest of the building.
fueling machine ![click to hear](/images/speaker.jpg)
Remote-controlled cylinder used to load and unload the reactor.
control room ![click to hear](/images/speaker.jpg)
Area that houses the personnel and equipment used to operate and monitor the power station.
steam release pipes ![click to hear](/images/speaker.jpg)
All the pipes used to carry steam to the separator outlet.
main steam pipes ![click to hear](/images/speaker.jpg)
All the pipes used to carry steam to the steam generator outlet.
main steam header ![click to hear](/images/speaker.jpg)
Device that collects and disperses steam from the steam generators.
condenser backwash outlet ![click to hear](/images/speaker.jpg)
Channel through which condensed water from the steam in the turbine returns to the water table.
condenser cooling water inlet ![click to hear](/images/speaker.jpg)
Channel through which water from a watercourse is pumped into the condenser.
condenser backwash inlet ![click to hear](/images/speaker.jpg)
Inlet channel for the water needed for the condensation circuit of the steam in the turbine.
condenser cooling water outlet ![click to hear](/images/speaker.jpg)
Channel through which the water from the condenser returns to the watercourse from which it came.
spent fuel storage bay ![click to hear](/images/speaker.jpg)
Water-filled basin where the spent fuel is stored for several years before it can be disposed of safely.
