Nuclear power Flashcards
Nuclear power explain in context
Most atomic nuclei are stable however some nuclei are not stable and emit particles that is known as radiation,
Radioactive decay is the process of when a unstable atom emits particles
What is Nuclear fission
During nuclear fission, scientists split nucleas of an atom into two smaller atoms, which releases huge amounts of energy
What is nuclear fusion
2 Atoms are brought together to create a new bigger Atoms,
during both of this reactions huge amounts heat and radiation are released.
What does nuclear power use
nuclear power uses nuclear fission, nuclear fusion and nuclear (radioactive) decay
Nuclear power uses what?
Nuclear power uses nuclear fission, nuclear fusion and nuclear (radioactive) decay.
what is good for fuel for energy in nuclear power
stations
Uranium undergoes radioactive decay at a slow pace making it a good element for fuel for energy
what is good for fuel for energy in nuclear power
stations
Uranium undergoes radioactive decay at a slow pace making it a good element for fuel for energy
Explain how a nuclear power station works
A nuclear power station has a Nuclear reactor vessel
were nuclear reaction take place and are controlled,
uranium is formed into pellets which are then arranged into long rods called the reactor core, The rods then form a bundle and are dipped into water to prevent them from overheating and melting, the large amounts of energy that were produced by the nuclear fission react with the uranium fuel rods which cause heat which then boils the water, steam then causes the turbines to rotate which transfers the kinetic energy to the generators Resulting in electricity.
Explain the disadvantages of nuclear power.
Once the nuclear fuel has been used it cannot be dumped into a city dump it becomes radioactive waste
and needs to be kept in a safe position to prevent harm to animals and plants or people using it.
overtime it becomes less radioactive but this can take thousands of years.
