Physics P2 - Energy from the nucleus
- Nuclear Fission
- Energy is released in a nuclear
reactor due to nuclear fission
- A chain reaction can occur
- A nucleus releases 2/3 neutrons
- It releases energy (radiation and kinetic)
- A chain reaction means a steady release
of energy is produced in a reactor
- Inside a nuclear reactor
- A nuclear reactor contains control rods and
fuel rods and high pressured water
- The water is a moderator that slows down
the collisions so it will be effective
- Control rods absorb extra neutrons -
this controls the chain
- The water acts as a coolant and is
pumped trhough the core
- The core is made of thick steel to withstand the
extreme temperatures within
- Nuclear fusion
- Two small nuclei release energy
when they fuse together and
form a larger nucleus
