Cutting the fuel supply
Damage to the reactor walls.

Question 9

What happens to the mass in a reaction

Answer 9

Mass is Converted into energy

Question 10

Why magnetic fields are used to contain the plasma inside the fusion reactor

Answer 10

So that plasma won’t cool down when it goes near the reactor walls. which makes it shut down
