TEPCO had that happen. Waste liquid (read: fissionable salts in solution) was being collected in a large, stainless (IIRC) bucket for disposal. When nearly full it went critical. One employee with a LARGE dose, many more with smaller doses, a huge cleanup bill, a huge fine. They should have also been deauthorized for this and another couple of incidents where bureaucratic carelessness spreading downwards led to nuclear accidents, but they had friends in the government.
A few years later several of their reactors melted down after the Fukushima tsunami.
