Nuclear Energy Christopher Liu, Michael Coppinger APES, Period 4

What is Nuclear Energy? Energy derived from nuclear reactions. o Currently, only through nuclear fission

How Does It Work?: Nuclear Fission Decay of an atom into two different atoms Produces energy (as heat) and additional neutrons as products

How Does It Work?: Nuclear Reactors

How are We Using It?: Domestic Current number of reactors in the US: 104 Local Reactors: Diablo Canyon o San Luis Obispo San Onofre o 45 miles SE of Long Beach

How are We Using it?: Domestic US is THE largest producer of nuclear energy Accounts for 19% of total energy output Produces 821 billion kWHs of energy annually

How are We Using It?: International 17% of energy production worldwide Over 430 plants Majority used for electricity production CountryPercent Reliance France77.7 Slovakia54.0 Belgium54.0 Ukraine47.2 Hungary43.3 Slovenia41.7

What are the Advantages? NO emissions NO air pollution NO water pollution Once built, reliable and cheap energy Uses small amounts of land Abundant fuel source

What are the Disadvantages? Produces radioactive waste o Must be stored and managed for thousands of years Potential terrorist acquisition Possibility of accidents o Chernobyl o Fukushima

How Likely is an Accident? Only three major accidents o Chernobyl (Doesn't count, they're Soviets) o Three Mile Island (Radiation was entirely contained) o Fukushima No known terrorist acquisitions

So, It's Safe? Coal vs. Nuclear; 4,000 deaths: 1 death One of the safest forms of energy production

What Can We Expect in the Future? Nuclear use will expand in future o China and India Possibility of cold fusion technology Radioactive waste? o Geological Repositories o Waste Reusel
