- Nuclear fission/ fussion
- Fission
- There are two fissionable substances in common use in the nuclear reactors: uranium and plutonium.
- The majority of nuclear reactors use uranium.
- Nuclear fission is the splitting of an atomic nucleus
- For fission to occur the uranium or pltioium nucleus must first absorb a neutron
- The nucleus undergoing fission spilts into two smaller nuclei and two or three neutrons and energy is realesed.
- The neutrons may go on to start a chain reaction
- We must be able to draw a chain reactor.
- There are two fissionable substances in common use in the nuclear reactors: uranium and plutonium.
- Fusion
- Nuclear fusion is the joining of two atomic nuclei to form a larger one.
- Nuclear fusion is the process by which energy is released in stars.
- Stars form when enough dust and gas from space is pulled together by gravitational attraction.
- Smaller also masses may form and be attracted by a larger mass to become plantets
- Durin period of its life cycle. This life cycle is determined by the size of the star.
- Fusion processes in stars produce all of the naturally ocurring elements.
