Would it be possible for a faction of the Soviet government to cause an intentional Chernobyl style disaster? The purpose would be to release large amounts of radiation over Europe or other unfriendly nations by finding a reactor with a vulnerable design near to the border with the proper wind and weather conditions to spread radiation mostly on enemy terrain? The disaster would be caused by assigning lower quality personnel to the nuclear plant and putting in a few special forces agents, in order to make it look like a pure accident.
