Which risk increases during deuterium-tritium fusion reactors if the plasma's density collapses below a critical threshold?

💡 Explanation

Neutron activation of the reactor's containment increases because decreased plasma density reduces the probability of neutron capture within the plasma via neutron moderation. Therefore, runaway neutrons escape more frequently, rather than being absorbed by the plasma, because lower density limits interaction probability.
