Nuclear Power

How Nuclear Energy is ProducedEnergy produced during a nuclear reaction is called Nuclear EnergyNuclear Fission and Nuclear Fusion are the two ways from which nuclear energy is producedSun is the natural example of nuclear energy source

Whole idea is based uponEinstein's mass-energy relation E = mc

Nuclear FissionSplitting of Heavier Nuclei into Larger NucleiBy Shooting Neutrons at them

Nuclear FusionTwo larger Nuclei combine to form heavier Nuclei

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

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 fuleWhy Nuclear Energy?

Status in Finland

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

Primary Energy Supplies in FinlandTVO has bought uranium from Canada, Australia and Africa

Fortum predecessor company IVOcontracted for a complete fuel supply service from Russia for the Loviisa

Uranium Mining and Waste ManagementThere 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

Interesting FactsNuclear energy is used to generate around 11% of the world's electricity, with almost no greenhouse gas emissions.

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.

Nuclear energy is used by more than 30 countries around the world. Nuclear technologies have many uses, including powering Mars rovers

Nuclear power plants can generate electricity continuously for many months at a time, without interruption.
