Nuclear Fission

Question 1

What is in a nuclear reactor

Answer 1

A controlled chain reaction that takes place in which atomic nuclei split up and release energy in the form of heat. The heat is used to heat water, the steam created is used to drive a turbine (connected to a generator)

Question 2

What is the fuel that is usually used in nuclear fission

Answer 2

Uranium or plutonium

Question 3

What is nuclear fisson?

Answer 3

A slow moving nuetron is absorbed into a uranium nucleus, which makes the nucleaus unstable, causing it to split. This usually creates two smaller nucleuses and two or three neutrons. These then go on to do more nuclear fission

Question 4

What is the main problem with nuclear power?

Answer 4

The disposal of waste as it is highly radioactive. They are very difficult and expensive to dispose of.

Question 5

Why is nuclear fission very expensive?

Answer 5

The power plant’s cost of setting up and decommissioning is extremely high
