Middletown, PA 1979
How it happened…• Non-nuclear portion of plant had a pump
malfunction.• This caused pressure to build in nuclear
part• A valve was opened to release pressure
and was stuck open, allowing coolant to leak out.
• Reactor core overheated, started meltdown, but did not breach containment building.

"Chernobyl. The war of all wars. There is no salvation for mankind anywhere. Not on earth,
not in the water, not in the sky."A villager in Belyibereg, Gomel
What happened?• Tests were being performed on the unit and
a variety of things “went wrong”– Too many control rods removed from coolant– Slowing turbine reduced water intake– Safety valves had been circumvented because
of testing– Poor communication between safety officials,
Radiation spread over 1000km
• Only 1 person died in explosion
• 44 within a week• Thousands have been
affected since– Thyroid cancer in
1978-1986 = 5 cases of childhood thyroid cancer.
– 1986-1998 = 600 cases!
• 19 years ago, Chernobyl exploded, vomiting 8 tons of radioactive ash into the air which swept across the lands poisoning 25% of the population and 25% of the lands of Belarus. And now the new generation of children bears its legacy through a horrifying and bewildering array of afflictions. Some children are born brain-damaged, others have genetic, physiological, neurological and psychological damage.
