    1. Disasters in Energy Production Nuclear and Coal

    2. Major Disasters in Nuclear Energy National Reactor Testing Station- Jan. 3, 1961 Three Mile Island- March 29, 1979 Chernobyl- April 26, 1986

    3. National Reactor Testing Station Desert near Idaho Falls, Idaho The only fatal nuclear accident in US Problem control rod was removed incorrectly from a low power reactor Caused the core to melt resulting in an explosion Killed 3 military members

    4. Three Mile Island Susquehanna River, Londonderry Township, south of Harrisburg, Pa Unit 1: 802 MWe Unit 2: 906 MWe Cooling system malfunction in Unit 2

    5. The coolant malfunction damaged and overheated the core 43,000 curies of Krypton Gas released 20 curies of iodine-131 released Leukemia an Lung Cancer were up to 10 times higher down wind Increased infant mortality for 2 years

    6. Chernobyl Ukraine, USSR, 1986 Number 4 reactor Went out of control during a low power test Officials ignored safety precautions and the Uranium overheated and melted through its encasings The reactor was not equipped with a dome to keep in radiation in case of accidents Graphite blocks used to help neutralize radiation also ignited and allowed air into the reactor 20 people were killed in the explosion 28 firefighters and emergency clean up personnel died from radiation within months

    7. 49,360 were evacuated within 36 hours from the nearest town of Priypat 200,000 people were eventually evacuated from the surrounding areas 1800 documented cases of thyroid cancer in children under the age of 14, no cases in cleanup workers Radioactive fallout reached for 150,000 sq km (approx 58,000 sq mi) Allowable amounts of fallout still exist in the area

    8. According to the International Atomic Energy Agency the safe limit for a residency is 5 Ci/km2

    9. Mining Quick Facts 2030 Coal Mines In Operation as of 2007 (1) 1453 in Kentucky, West Virginia, and Pennsylvania 1.2 Billion Tons of Coal Mined in 2007(2) 726 Total Mining Incidents of More Than 5 Fatalities 1839-2007 in U.S. (3) 622 Mining Coal

    10. United States of America 34 Fatalities and 3,402 Injuries Reported in 2007 Monongah Mining Disaster was worst in US history: 362 men killed in 1907 Sago Mine Disaster in 2006 killed 12 miners in an explosion in Sago, West Virginia 1 miner survived, while in the mine for 2 days

    13. Canada 26 miners killed in 1992 on Nova Scotia following a coal dust explosion Spring Hill Mining Disaster Worst in Canadian History Spring Hill, Nova Scotia 1891- Fire Est. killed 120, dozens wounded 1956- Explosion 39 killed, 88 rescued 1958- Bump 74 killed, 100 rescued

    14. China Largest coal deposits in the world 80% of mining deaths 34% of coal mined Apr. 26 1942- Benxihu Colliery- coal dust explosion killed 1,549 miners In 2006 4,726 miners were killed

    15. United Kingdom No disaster since 1979 Range Total 1700-1750 93 1750-1800 267 1800-1850 3,486 1850-1900 59,580 1900-1950 84,331 1950-2000 16,599 Total 164356

    17. Centralia, Pa
