I never said anything about an explosion. I'm pointing out the effect of a radiation leak from a reactor that is, by definition, leagues above any fusion reactor we have created today.

Fusion reactor we have today work by heating gasses to their fusion point, and as soon as we stop heating them, they repel each other again. Thus the reaction stops. Any reactor that powers something, and as such creates a net positive energy output, will need to be self sustaining. In other words, when the reactor is breached, it will not instantly stop the reaction.

The reaction will continue after reactor breach. Eventually it will collapse, yes, but it is not instant. And until it does you will have an unconfined reaction occurring. Which will both put off a ton of radiation and, yes, have explosive potential. A fusion bomb is [i]by definition[/i] an uncontained fusion reaction.

Fusion reactors are only safe by government standards because none of the ones we have created, [i]ever[/i], are on anywhere near the level of what would be powering Gren.
