Presentations by class mates

• 2 days of research for topics mentioned. See me if a picture in the text is something you would like to include.

• 2 days of presentations by classmates.• Grade will be a group grade – pick your

partners wisely!• Grade for notes taken during

presentations.• Test over 17 and 18 Nov. 20th

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• Ukraine (former USSR)

"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,

testing officials.

Radiation spread over 1000km

Health effects

• 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.
