This is nowhere near "the worst." Dangers of nuclear reactors are deliberately exaggerated by those with an agenda in order to ensure the public reacts in fright to the word "nuclear." Medical MRI machines were initially called Nuclear Magnetic Resonance scanners (NMR). They had to change the name to get people to accept them.

This reactor isn't much danger even if all the water leaks away. It's not a POWER reactor producting large quantities of fission products.

I agree with unimogbert. It's a nonhazard and you have nothing to worry about. I have toured PSUs reactor and it is a standard TRIGA research reactor, much like the one at Texas A&M and other universities. The water has such low levels of activation products that you could probably drink it without much of a dose consequence.

My advice is to use this as an excuse to drink more beer to flush your system of potential "contaminants". I recommend Otto's brewery as a good place to start.
