UK Threat Levels The current level was reduced to Severe on the afternoon of 17 September 2017/[2] It had been raised to Critical following the 2017 Parsons Green bombing on 15 September.[3]
Chernobyl disaster The event occurred during a late-night safety test which simulated a station blackout power-failure, in the course of which safety systems were intentionally turned off. A combination of inherent reactor design flaws and the reactor operators arranging the core in a manner contrary to the checklist for the test, eventually resulted in uncontrolled reaction conditions. Water flashed into steam generating a destructive steam explosion and a subsequent open-air graphite fire.[note 1] This fire produced considerable updrafts for about nine days. These lofted plumes of fission products into the atmosphere. The estimated radioactive inventory that was released during this very hot fire phase approximately equaled in magnitude the airborne fission products released in the initial destructive explosion.[3] Practically all of this radioactive material would then go on to fall-out/precipitate onto much of the surface of the western USSR and Europe.
