Here's one random incident/accident from each country mentioned:
“The worst previous incident at a Japanese nuclear facility was at a uranium processing plant in Tokaimura, north of Tokyo, in September 1999, when an uncontrolled nuclear chain reaction was triggered by three poorly trained workers who used buckets to mix nuclear fuel in a tub. The resulting release of radiation killed two workers and forced the evacuation of thousands of nearby residents.”

“Radioactive contamination detected at the Fairlie station where spent fuel flasks from Hunterston are transferred to flat bed railway trucks on their way to Sellafield. Caesium 137 levels were 30 times greater than the highest post Chernobyl concentrations and 100 times the levels found in Strathalyde where the station is located.”
