Even though the Chornobyl nuclear accident occurred more than 30 years ago, there are many questions still open about why and how that happened and how the Soviet authorities responded. Ukraine’s Security Service has now published 190 KGB documents which cover the period from 1970 to November 1986.

According to documents in the book, between 1971 and 1981 alone, the atomic power plant suffered accidents, eight of which were the fault of operators and the rest apparently because of poor construction materials. In 1984, the KGB warned that the facility was an accident waiting to happen because of problems with the reactor that eventually melted down.

But perhaps the most disturbing report contained in these documents is that the KGB itself noted that after the accident when operators fled the scene, no one was in control of the operation of the facility “for some time,” a situation that likely made the consequences of the accident even worse.
