This fear seems to have been largely played up for drama. My understanding of the situation is that at one point they went 'Huh, we could potentially set off a chain reaction here. We should check out if the math adds up on that.'

Then they went off and did the math and quickly found that this wouldn't happen because the amount of energy in play here was order of magnitudes lower than what would be needed for such a thing to occur and went on about their day.

The only reason it's something we talk about is because of the nature of the outcome, not how seriously the physicists were in their fear.
