There are several identical reactors in use at a nuclear power plant called Ignalina in Lithuania. It's like "the sister" of Chernobyl. The name was mentioned a lot just after the accident. But the view of experts was that it was in fact safe. I guess that's a good reflection on the design.
Apparently that it is still in use; the Lithuanians refuse to close it, despite the EU insisting on it. I don't know what reservations the EU has though. Lithuania has no other good source of power and any alternative would make them too dependent on imports and "dirty energy" like coal.
I saw the documentary that's mentioned here, and IF the information in that reconstruction is true; then Dyagilev has a lot of lives on his conscience!! It's hard to imagine that anyone can decide to ignore safety regulations at a nuclear power plant...
