Fission And Fusion
Bayani Gaba-gaba
Burning coal releases the energy stored in chemical bonds between atoms. Nuclear reactions reach far deeper, into the nucleus itself, and release something like a million times more energy from the same mass of fuel. Two quite different nuclear processes do this, and confusing them is the classic error in this topic.
This lesson separates them properly. Fission splits one heavy nucleus into two lighter ones and runs every nuclear power station on Earth. Fusion joins light nuclei together and powers every star in the sky. You will meet the chain reaction, the job of the control rods and the shielding, and the reason fusion is so much harder to achieve on Earth than in the Sun.
Manufura
- Know that nuclear reactions, including fission, fusion and radioactive decay can be a source of energy
- Understand how a nucleus of U-235 can be split (the process of fission) by collision with a neutron, and that this process releases energy as kinetic energy of the fission products
- Know that the fission of U-235 produces two radioactive daughter nuclei and a small number of neutrons
- Understand the role of shielding around a nuclear reactor
- Know that fusion is the energy source for stars
