Question: What is the most efficient way of storing nuclear energy?

Megan Seymour answered on 9 Nov 2016:

Nuclear energy is a very difficult thing to actually store- it is locked up inside the radioactive metals until a nuclear chain reaction is triggered inside a nuclear reactor, and then a lot of energy is released very quickly.
Inside a nuclear power station this energy is temporarily stored as heat (heat from the nuclear reaction is used to warm up water- turning it into steam). The steam is then used to spin turbines which create motion inside a generator to produce electricity.
This electricity usually goes straight out to the national grid which supplies our homes and businesses with electricity, but could, I suppose, be used to charge a giant battery as a way of storing the energy.
