Depending on the stainless steel alloy composition -- and the quality of the welds in that stainless catch-basin, those Brits should be concerned about having that much strong oxidizer (conc. HNO₃) on the loose -- radioactive or not...

Not the sort of thing I'd want anywhere near my water supply...

I was thinking the same- how long before it eats through those welds...

Sure would suck to be an engineer at that place today.
