• Condenser
• Alternator

3. Nuclear Reactor
 A nuclear reactor produces and controls the release of energy from
splitting the atoms of certain elements. In a nuclear power reactor, the
energy released is used as heat to make steam to generate electricity

4. Nuclear Reactor - Fuels
 Uranium (UF6) is a relatively common element that is found throughout
the world. It must be processed before it can be used as fuel for a nuclear
reactor.
 To prepare uranium for use in a nuclear reactor, it undergoes the steps of
mining and milling, conversion, enrichment and fuel fabrication. These
steps make up the 'front end' of the nuclear fuel cycle.

5. Nuclear Reactor - Moderator
 Moderator is theMaterial in the core which slows down the neutrons
released from fission so that they cause more fission.
 It is usually water, but may be heavy water or graphite.

6. Nuclear Reactor – Controll Rods
 The control rods prevent the chain reaction happening too quickly i.e.
controls chain reaction
 Control rods are made from an alloy of silver and cadmium, boron mixed
with iron or carbon.
 The control rods are very good at absorbing neutrons. They reduce
the number of neutrons available to continue the chain reaction.

7. Nuclear Reactor -
Coolant,Pressure Vessele,Steam Generator
 Coolant. A fluid circulating through the core so as to transfer the heat
from it. In light water reactors the water moderator functions also as
primary coolant.
 Pressure vessel or pressure tubes. Usually a robust steel vessel containing
the reactor core and moderator/coolant, but it may be a series of tubes
holding the fuel and conveying the coolant through the surrounding
moderator.
 Steam generator. Part of the cooling system of pressurised water reactors
where the high-pressure primary coolant bringing heat from the reactor is
used to make steam for the turbine, in a secondary circuit. Essentially a
heat exchanger like a motor car radiator*. Reactors have up to six 'loops',
each with a steam generator.

9. Heat exchanger
 A heat exchanger is a device built for efficient heat transfer from one
medium to another, whether the media are separated by a solid wall so
that they never mix, or the media are in direct contact.
 Heat exchangers are used to convert water into steam from heat produced
in a nuclear reactor core.

10. Steam Turbie
 Converts heat energy of the system into Mechenical energy

11. Cooling Tower
 Cooling TowerRemoves heat from the water discharged from the
condenser so that the water can be discharged to the river or recirculated
and reused.
 Major Components :
 Cooling Tower(supply) basin
 Cooling Tower Pumps
 There are 2 types of towers - Mechanical draft and Natural draft
