Russia has had several significant nuclear material release incidents in the last twenty years, only detected because the waste/fallout plume reached monitoring sites outside the country. The most recent was the 2018 disaster involving a nuclear torpedo. Russia has used its reactors to produce materials to conduct political assassinations on foreign soil, which have ended up injuring and contaminating many innocent people.
