WHAT IS NUCLEAR ENERGY
The Big Bang. All bodies in space are made up of the same matter, including living-beings. Composition of matter – aproximately 100 elements. Atoms – their definition, structure and composition. Atomic numbers of different elements. First nuclear fission ever carried out by Otto Hahn. Albert Einstein and the relation between mass and energy. Nuclear reactors. Radioactive materials.

INTRODUCTION
- The “Big Bang” gave birth to our universe some 15,000 million years ago.
- Our entire known universe is made up of energy and matter and matter is nothing more than a concentrated form of energy.
- Interrelationship between matter and energy
- All matter is made up of some 100 elements which combine amongst themselves and form the tremendous variety of compounds present in Nature.
- The Atom. Protons, neutrons, electrons.
- Electrical energy
- Nuclear forces
NUCLEAR ENERGY
- Elements differ from one another in the size and structure of their atoms, though they are all made up from the same particles.
- Atomic nucleus
- Atomic numbers of the different elements
- Nuclear fission
- Nuclear forces
NUCLEAR FISSION
- Nuclear energy
- Albert Einstein: relationship between mass and energy
- Chain-reaction
- Nuclear explosion. Scenes taken after the explosion in Hiroshima.
- Nuclear reactor. How does it work?
- The radio active products waste
NUCLEAR FUSION
- What is a nuclear fusion?
- The atomic bomb or “H” bomb
- The Sun: a huge fusion power-plant
- Power-plants using nuclear fusion will not be operative before the year 2050.
- Fusion advantages over nuclear fission
