Nuclear power

Nuclear power. How does it work?. A neutron hits a uranium-235 atom. The atom divides in one strontium-90, one Xenon-143 and three neutrons. Energy releases and heats up the water. The water turns into water steam.

  1. Nuclear power

  2. How does it work? • A neutron hits a uranium-235 atom. • The atom divides in one strontium-90, one Xenon-143 and three neutrons. • Energy releases and heats up the water. The water turns into water steam. • The steam goes through a turbine that runs a generator which produces electricity

  3. Nuclear power in Sweden • In Sweden we have 10 reactors producing energy • The produced electricity from nuclear power is 64,3 TWh. It’s about half of the total 145 TWh, 2007. • Hydroelectric power and nuclear power in Sweden stand for almost 90% of the total electricity production. • If all the diodes in Sweden should be turned of we could turn of a reactor.

  4. Nuclear power - good and bad • Good: • Cheap energy. • It doesn’t let out any harmful things to the environment. • One reactor produces much electricity. • Bad: • There’s a risk that an accident can happen, for example a meltdown. • The plant is expensive. • The waste can be much radioactive and it takes long time before it gets risk-free, up to more than 100 000 years.

  5. Total energy supplied: Oil: 201 TWh Nuclear power: 194 TWh Bioenergy: 116 TWh Water power: 62 TWh Coal: 28 TWh Gas: 11 TWh Heat pumps: 6 TWh Wind power: 1 TWh Total: 618 TWh Losses and use for non-energy purposes:222 TWh Total final use per energy carrier:397 TWh Energy production in Sweden (2006)
