Dauphin County near Harrisburg, Pennsylvania - Partial core meltdown of a pressurized water reactor - Accident began at 4:00 a.m. Wednesday, March 25, 1979 - Started with a loss of nuclear reactor coolant - 12 days prior, The China Syndrome depicted an accident at a nuclear reactor - Voluntary evacuation of five mile radius (140,000 people leave) - TMI 1 still in use
Chernobyl April 26, 1986 WORST NUCLEAR POWER PLANT ACCIDENT IN HISTORY
- Chernobyl Nuclear Power Plant in Pripyat, Ukraine (then Ukrainian Soviet Socialist Republic) - Reactor #4 experienced a sudden and unexpected power surge - Emergency shutdown attempted leads to exponentially larger power surge - Series of explosions exposes graphite moderator to air and it ignites - Fire sends plume of highly radioactive fallout into the atmosphere (mainly over Soviet Union and much of Europe)
- 1986-2000: 350,400 people evacuated - Last reactor shut down in 2000 - Fifty deaths directly from accident - 4,000 deaths attributed - 400x more radioactive material than the atomic bombing of Hiroshima
The accident raised concerns about the safety of the Soviet nuclear power industry, as well as nuclear power in general, slowing its expansion for a number of years and forcing the Soviet government to become less secretive about its procedures. The government cover-up of the Chernobyl disaster was a "catalyst" for glasnost (openness), which "paved the way for reforms leading to the Soviet collapse."
Exxon Valdez - March 24, 1989 - Prince William Sound, Alaska
- Oil tanker spilled 260,000-750,000 barrels (10-11 million gallons) of crude oil - Covered 1300 miles of coastline and 11,000 square miles of ocean - Deepwater Horizon spill: - 4.9 million barrels
Both the long-term and short-term effects of the oil spill have been studied. Immediate effects included the deaths of, at the best estimates, 100,000 to as many as 250,000 seabirds, at least 2,800 sea otters, approximately 12 river otters, 300 harbor seals, 247 Bald Eagles, and 22 orcas, and an unknown number of salmon and herring. The effects of the spill continued to be felt for many years afterwards. Overall reductions in population were seen in various ocean animals, including stunted growth in pink salmon populations. The effect on salmon and other prey populations in turn adversely affected killer whales in Prince William Sound and Alaska's Kenai Fjords region. - Wikipedia
WHY DO WE CARE!? In all seriousness, they are accidents...what is our duty as citizens of this nation, and more importantly, this world to the environment? Write a paragraph response for why we should care and what we can do to help prevent this from happening.
