Chernobyl accident

Igor Kudrik

The very word Chernobyl has become synonymous with catastrophe since the Ukraine based plant’s reactor No. 4 exploded in the early morning hours of April 26, 1986, spreading radioactive fall-out as far north as Scandinavia. Chernobyl ran on the water cooled graphite moderated RBMK type reactor that has since been deemed fatally flawed by experts. The accident began with an ill-planned experiment to suck extra energy out of the turbines after the reactor had been cooled. Operators where controlling the reactor manually. Water pressure in the reactor’s damp feeds built to an uncontrollable point and the operators pushed the emergency stop button. The damp feeds in the core exploded shortly thereafter, and the consequent heat build up blew the lid off of the reactor, spreading 3 million TBq of radiation―95,000 TBqs of which were of the long-lived elements like caesium, strontium and plutonium. Official death tolls are hard to reckon. Thirrty workers were killed immediately in the blast, but the radiation spread continues to claim countless victims.

ANALYSIS: Roof collapse at Chernobyl: What does it mean for Russia’s aged Chernobyl-type reactors?
MOSCOW/ SLAVUTCH, Ukraine – A “combination of negative factors” rather than excessive snowfall was the cause of the February 12 partial wall and roof collapse at Chernobyl’s infamous Reactor Unit 4, recent findings of two commissions that investigated the incident revealed. Notably, the risk of concrete slabs collapsing over the reactor halls of the defunct nuclear plant’s three other units had been discussed just one day earlier, on February 11, in Ukraine’s Slavutich. And Russia has three stations running Chernobyl-type reactors, RBMK-1000s – all three of similar or older ages and still in operation. How badly should Russia be concerned about its old stations’ safety?

Demonstrators in Russia use 26th Chernobyl anniversary to insist on righting pervasive nuclear defects
MOSCOW/MURMANSK - Activists across Russia Thursday used the 26th anniversary of the disaster at Chernobyl to spotlight ongoing problems in the country’s ailing nuclear industry – many of which demonstrators say could lead to a Chernobyl take two as government and industry officials persistently ignore the lessons of Fukushima.
