 This is bullshit. There only two VVER vessels in the world protected by "free world" definition containment buildings. They both stand in Finland and they are soviet-czech made VVER-440 vessels, which were installed under honest concrete bunkers from the first minute, at the special insistance of the finns. (If the reactor blows up, the finns can never again export their wood or paper due to pollution and that's economy domesday scenario for them.) 

 All other VVER vessels, as they stand in ex-WARPAC/COMECON countries, are located inside large barns/sheds with very limited over-pressure resistance and zero missile repelling capability. Some of them, however, like those at Paks, Hungary are equipped with an auxillary emergency tower, wich has huge trays of boric cid water in them. If the reactor blows up, that water is supposed to absorb a large part of the radiactive product. However, it would be an outright lie to call that containment. 

 Admit no containment can stop a full-speed impacting An-124 giant cargo plane loaded with a 109-ton diesel locomotive in its belly, but COMECON-standard VVER-440 reactor housing sheds are penetrable by african swifts on a good summer day... 8-(
