The open core also allowed atmospheric oxygen to contact the super-hot core containing 1,700 tonnes[8] of combustible graphite moderator. The burning graphite moderator increased the emission of radioactive particles, carried by the smoke. The reactor was not contained by any kind of hard containment vessel (unlike all Western plants, Soviet reactors often did not have them).[9] Radioactive particles were carried by wind across international borders,
First over an extensive geographical area, including the nearby town of Pripyat, 18 km NW of the city of Chernobyl.
