What are the practical difficulties in the operation of a fusion reactor a large scale? 2 marks.

The main difficulty is that the temperature and pressure required for the reaction produced are very large. The state of matter at these temperatures is something called plasma, and AA-type material there is gas where atoms are ionized (electron stripes on them) There is no substance that can withstand these conditions and remain in a solid form. As a way they're trying to do this is by containing the plasma in a field magnetic (exceptionally high power field). The merger has been successfully achieved in a laboratory on a small scale, but be long before click on a commercial basis. With respect to environmental problems is the cleanest fuel available, producing mainly as a byproduct.
