Nuclear energy is produced through two main reactions: nuclear fission and nuclear fusion. Nuclear fission involves splitting heavier nuclei into larger nuclei by shooting neutrons at them, while nuclear fusion involves combining two larger nuclei to form heavier nuclei. Nuclear power plants use these reactions to generate extreme heat and produce steam that spins turbines to generate electricity. Finland obtains about 30% of its electricity from four nuclear reactors, with plans to build more, and manages nuclear waste through long-term storage and planned deep geological disposal.

3. How Nuclear Energy is Produced
Energy produced during a nuclear reaction is called Nuclear
Energy
Nuclear Fission and Nuclear Fusion are the two ways from which nuclear
energy is produced
Sun is the natural example of nuclear energy
source
Whole idea is based uponEinstein's mass-energy relation
E = mc ²

4. Nuclear Fission
Splitting of Heavier Nuclei into Larger Nuclei
By Shooting Neutrons at them

5. Nuclear Fusion
Two larger Nuclei combine to form heavier Nuclei

6.  Basic principle of nuclear powerplant is to obtain
extreme heat energy which is used to boil water
and convert it into vapour.
 Vapour is then used to rotate the turbine , finally
mechanical energy of turbine is converted into
electrical energy.
Basic Principle

8.  Electricity demand is increasing twice as
fast as overall energy use and is likely to
rise by more than two-thirds 2011 to 2035.
 Only environmental friendly way to
produce electricity in large scale
 Best alternate of fossil fule

12.  Finland has four nuclear reactors(Loviisa plant and Olkiluoto plant) providing nearly 30% of its electricity.
 A fifth reactor is now under construction and two more are planned.
 Provisions for disposal of nuclear waste are well advanced.
 First power plant came in operation in 1977 AD

13. Primary Energy Supplies in Finland
• TVO has bought uranium from
Canada, Australia and Africa
• Fortum predecessor company
IVO contracted for a complete fuel
supply service from Russia for the
Loviisa

14. Uranium Mining and Waste Management
There has been no Uranimium
mining in finland.
Areva Resources in Finland has
appliced for uranium mining
claim south of Rovaniemi ,
Lapland.
At Olkiluoto a surface pool storage for spent fuel has
been in operation since 1987. This KPA facility has
1270 tonne capacity and is designed to hold used
fuel for about 50 years, pending deep geological
disposal

15. Advantages
Produces large amount of energy
Green Energy
No Air Pollution
Fuel Independence

16. Disadvantage
 Radiation
 Non-Renewable
 Developing Nuclear Weapens
 Huge Building Cost
 Nuclear Waste
 Nuclear Power Plant Accidents

17. ɕ Nuclear energy is used to generate around 11% of the world's electricity,
with almost no greenhouse gas emissions.
ɕ A single uranium fuel pellet contains as much energy as 480 cubic metres
of natural gas, 807 kilos of coal or 149 gallons of oil.
ɕ Nuclear energy is used by more than 30 countries around the world.
Nuclear technologies have many uses, including powering Mars rovers
ɕ Nuclear power plants can generate electricity continuously for many
months at a time, without interruption.
