Nuclear Energy in the U.S. Juliet, Thurman, Conner, and Taylor
What is Nuclear Energy? • What is it? • Capturing atomic nuclei for energy use for people • Two kinds: • Fission • Fusion • Most common form of fission involves splitting Uranium 235
Fission • What is it? • Splitting of two atoms into smaller pieces • Fission produces smaller pieces of the atom, along with more energy, and electromagnetic radiation • Fission of Uranium produces resources by; Produces heat -> produces steam -> steam drives turbines to create electricity
Fusion • What is it? • Pairing small atoms together to become one to release large amounts of energy
History • 1939- development of nuclear fission began in labs • 1940- Manhattan project (secret military objective to build the first nuclear weapon Atomic Bomb) • 1950’s-1980- popularity of nuclear energy was an increased way of producing energy • 1980’s- popularity decreased due to cost restraints
Current Statistics in the U.S. • 61 Nuclear Power Plants • 99 Nuclear Reactors • Spread among 30 states • Makes up about 19% of the U.S. energy • No way to get rid of the waste
Waste from Nuclear Energy • Budget of $32 million set aside for the storage of the waste • Stored underground and in the reactors • Waste keeps piling up • Affects the surrounding environment where it is stored
Waste from Nuclear Energy cont. • Low-level waste • Includes items that have been contaminated by radioactive material • Intermediate-level waste • Filters, steel components, other various parts of the reactor • High-level waste • -Highly radioactive materials produced as a byproduct of the reaction from nuclear fission
How Waste Is Managed • Two acceptable and regulated methods of storing nuclear waste • Spent Fuel Pools: are placed in the reactor and contain at least 20 feet of water, there are neutron absorbing materials placed as a barrier in the fuel pool • Dry Cask Storage: developed as an alternative when fuel pools began, allows waste that has spent a year in the fuel pool is placed in leak-confined steel cyclinders
Future of Nuclear Energy in the U.S. • Use of nuclear power within the states appears limited • Optimists may believe there will be a surge with nuclear power once again due to more efficient plants and safer more advanced equipment • Nuclear power is quickly becoming outsourced as an energy resource by other forms of energy such as natural gas • The cost of continuing to run nuclear power plants and stockpile the waste is beginning to outweigh the rewards and efficiency of nuclear energy
