high-pressure steam inlet click to hear : high-pressure steam inlet

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 : separator

Device that removes any water from the steam to prevent damage to the turbine’s runner.

turbine stop valve click to hear : turbine stop valve

Device that blocks steam from entering the turbine.

reheater click to hear : reheater

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 : condenser water outlet

Water in the condenser returns to its original source.

low-pressure steam inlet click to hear : low-pressure steam inlet

Heated steam is reinjected into the turbine, where it releases its remaining energy.

condenser click to hear : condenser

Water collected from the water table flows in a circuit to cool the steam from the turbine and condense it into water.

transformer click to hear : transformer

Device used to alter the electric voltage; the voltage is increased at the station outlet in order to carry the current over long distances.

turbine click to hear : turbine

Machine in two sections whose steam-activated runner transmits mechanical energy to the rotor shaft of the generator.

generator click to hear : generator

Turbine-powered rotating machine that converts mechanical energy into electric energy to direct it toward a transmission network.

turbine building click to hear : turbine building

Enclosure housing the devices (turbines and generator) used to produce electricity.

spent fuel discharge bay click to hear : spent fuel discharge bay

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 : reactor building airlock

Secure area where equipment and personnel can pass safely through the reactor building.

dousing water valve click to hear : dousing water valve

Device that releases water from the dousing water tank in the reactor building to condense the radioactive steam.

steam generator click to hear : steam generator

Apparatus that turns water into steam, which in turn activates the turbine.

dousing water tank click to hear : dousing water tank

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 : reactor building

Concrete structure surrounding the reactor vessel; it is a protective barrier against radioactivity.

steam generator room cooler click to hear : steam generator room cooler

Cooling system that controls the temperature of the room housing the generators.

deuterium oxide upgrading click to hear : deuterium oxide upgrading

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 : heat transport pump

Apparatus that circulates the coolant fluid between the reactor and the steam generator.

feeder header click to hear : feeder header

Large-diameter pipe that collects the coolant fluid at the reactor inlet and outlet.

reactor click to hear : reactor

Tightly sealed area where fission of the fuel is carried out in a controlled manner to release heat.

calandria click to hear : calandria

Safety containment wall that separates the reactor from the rest of the building.

fueling machine click to hear : fueling machine

Remote-controlled cylinder used to load and unload the reactor.

control room click to hear : control room

Area that houses the personnel and equipment used to operate and monitor the power station.

steam release pipes click to hear : steam release pipes

All the pipes used to carry steam to the separator outlet.

main steam pipes click to hear : main steam pipes

All the pipes used to carry steam to the steam generator outlet.

main steam header click to hear : main steam header

Device that collects and disperses steam from the steam generators.

condenser backwash outlet click to hear : condenser backwash outlet

Channel through which condensed water from the steam in the turbine returns to the water table.

condenser cooling water inlet click to hear : condenser cooling water inlet

Channel through which water from a watercourse is pumped into the condenser.

condenser backwash inlet click to hear : condenser backwash inlet

Inlet channel for the water needed for the condensation circuit of the steam in the turbine.

condenser cooling water outlet click to hear : condenser cooling water outlet

Channel through which the water from the condenser returns to the watercourse from which it came.

spent fuel storage bay click to hear : spent fuel storage bay

Water-filled basin where the spent fuel is stored for several years before it can be disposed of safely.
