1
Fallout from Chernobyl
3
400 million people exposed in 20 countries
5
Chernobyl’s political fallout
Stimulated Gorbachev’s glasnost (openness) Stimulated nationalism in Ukraine, Belarus, and other republics that lost clean-up workers. Growth of environmental opposition Questioning of the heart of technocratic power Soviet leaders were engineers, not lawyers USSR collapsed within 5 years.
6
Radiation and Health Health effects as a result of radiation exposure:
-increased likelihood of cancer -birth defects including long limbs, brain damage, conjoined stillborn twins -reduced immunity -genetic damage
7
3.5 million sick, one/third of them children
8,000 deaths in 14 years 3.5 million sick, one/third of them children

“It Can’t Happen Here” U.S. reaction to Chernobyl, 1986
Blamed on Communism, graphite reactor Also Soviet reaction to Three-Mile Island, 1979 Blamed on Capitalism, pressurized-water reactor No technology 100% safe Three-Mile Island bubble almost burst
16
Three-Mile Island, PA 1979
18
Health around TMI In 1979, hundreds of people reported nausea, vomiting, hair loss, and skin rashes. Many pets were reported dead or showed signs of radiation Lung cancer, and leukemia rates increased 2 to 10 times in areas within 10 miles downwind Farmers received severe monetary losses due to deformities in livestock and crops after the disaster that are still occurring today.
19
Plants near TMI -lack of chlorophyll -deformed leaf patterns
-thick, flat, hollow stems -missing reproductive parts -abnormally large TMI dandelion leaf at right
20
Animals Nearby TMI Many insects disappeared for years.
Bumble bees, carpenter bees, certain type caterpillars, or daddy-long-leg spiders Pheasants and hop toads have disappeared.
21
Nuclear reaction Chain reaction occurs when a Uranium atom splits
Different reactions Atomic Bomb in a split second Nuclear Power Reactor more controlled, cannot explode like a bomb
22
History of nuclear power
1938– Scientists study Uranium nucleus 1941 – Manhattan Project begins 1942 – Controlled nuclear chain reaction 1945 – U.S. uses two atomic bombs on Japan 1949 – Soviets develop atomic bomb 1952 – U.S. tests hydrogen bomb 1955 – First U.S. nuclear submarine
23
“Atoms for Peace” Program to justify nuclear technology
Proposals for power, canal-building, exports First commercial power plant, Illinois 1960
24
Economic advantages The energy in one pound of highly enriched Uranium is comparable to that of one million gallons of gasoline. One million times as much energy in one pound of Uranium as in one pound of coal.
25
Emissions Free Nuclear energy annually prevents
5.1 million tons of sulfur 2.4 million tons of nitrogen oxide 164 metric tons of carbon Nuclear often pitted against fossil fuels Some coal contains radioactivity Nuclear plants have released low-level radiation
26
Early knowledge of risks
1964 Atomic Energy Commission report on possible reactor accident 45,000 dead 100,000 injured $17 billion in damages Area the size of Pennsylvania contaminated
27
States with nuclear power plant(s)
28
Nuclear power around the globe
17% of world’s electricity from nuclear power U.S. about 20% (2nd largest source) 431 nuclear plants in 31 countries 103 of them in the U.S. Built none since 1970s (Wisconsin as leader). U.S. firms have exported nukes. Push from Bush/Cheney for new nukes.
29
Countries Generating Most Nuclear Power
Country Total MW USA 99,784 France 58,493 Japan 38,875 Germany 22,657 Russia 19,843 Canada 15,755 Ukraine 12,679 United Kingdom 11,720 Sweden 10,002 South Korea 8,170
32
Nuclear fuel cycle Uranium mining and milling
Conversion and enrichment Fuel rod fabrication POWER REACTOR Reprocessing, or Radioactive waste disposal Low-level in commercial facilities High level at plants or underground repository
33
Front end: Uranium mining and milling
34
Uranium tailings and radon gas
Deaths of Navajo miners since 1950s
35
Uranium enrichment U-235 U-238 Plutonium-239 Fissionable at 3%
Weapons grade at 90% U-238 More stable Plutonium-239 Created from U-238; highly radioactive
36
Radioactivity of plutonium
Life span of least 240,000 years Last Ice Age glaciation was 10,000 years ago Neanderthal Man died out 30,000 years ago
37
Risks of enrichment and fuel fabrication
Largest industrial users of water, electricity Paducah, KY, Oak Ridge, TN, Portsmouth, OH Cancers and leukemia among workers Fires and mass exposure. Karen Silkwood at Oklahoma fabrication plant. Risk of theft of bomb material.
39
Nuclear Reactor Process
3% enriched Uranium pellets formed into rods, which are formed into bundles Bundles submerged in water coolant inside pressure vessel, with control rods. Bundles must be SUPERCRITICAL; will overheat and melt if no control rods. Reaction converts water to steam, which powers steam turbine
40
Technology depends on operators
41
Other reactor accidents (besides TMI and Chernobyl)
1952 Chalk River, Ontario Partial core meltdown 1957 Windscale, England Graphite reactor fire contaminates 200 square miles. 1975 Browns Ferry, Alabama Plant caught fire 1976 Lubmin, East Germany Near meltdown of reactor core . 1999 Tokaimura, Japan Nuclear fuel plant spewed high levels of radioactive gas
43
United States
44
Risk of terrorism (new challenge to industry)
9/11 jet passed near Indian Point
45
Nuclear Reactor Structure
Reactor’s pressure vessel typically housed in 8” of steel 36” concrete shielding 45” steel reinforced concrete
47
Breeder reactor “Breeds” plutonium as it operates
Uses liquid sodium metal instead of water for coolant Could explode if in contact with air or water 1966 Fermi, Michigan Partial meltdown nearly causes evacuation of Detroit 1973 Shevchenko, Russia Breeder caught fire and exploded Controversial proposals in Europe, U.S.
49
Reprocessing Separates reusable fuel from waste 1960s West Valley, NY
Large amounts of radioactivity released 1960s West Valley, NY Radiation leaked into Lake Ontario 1970s La Hague, France Released plutonium plumes into air
50
Back end: Radioactive wastes
Low-level wastes in commercial facilities Spent fuel in pools or “dry casks” by plants Nuclear lab wastes Hanford wastes leaked radiation into Columbia River High-level underground repository Yucca Mountain in Nevada to 2037 Wolf River Batholith in Wisconsin after 2037? Risks of cracks in bedrock, water seepage

55
Kyshtym waste disaster, 1957
Orphans Explosion at Soviet weapons factory forces evacuation of over 10,000 people in Ural Mts. Area size of Rhode Island still uninhabited; thousands of cancers reported
57
Radioactive Waste Recycling
Disposal of radioactive waste from nuclear power plants and weapons facilities by recycling it into household products. In 1996, 15,000 tons of metal were received by the Association of Radioactive Metal Recyclers . Much was recycled into products without consumer knowledge. Depleted Uranium munitions for military.
58
Summary Nuclear energy has no typical pollutants or greenhouse gasses
Nuclear waste contains high levels of radioactive waste, which are active for hundreds of thousands of years. The controversy around nuclear energy stems from all parts of the nuclear chain.
