APESCH19
| Term | Definition |
|---|---|
| Black Lung Disease | Inflamation and fibrosis caused by accumulation of coal dust in the lungs or airways |
| Breeder Reactors | a nuclear reactor that produces fuel by bombarding isotopes of uranium and thorium with high-energy neutrons that convert inert atoms to fissionable ones |
| Calorie | |
| Carbon Sequestration | storing carbon (usually in the form of CO2) in geological formations or at the bottom of the ocean |
| Chain Reaction | a self-sustaining reaction in which the fission of nuclei produces subatomic particles that cause the fission of other nuclei |
| Coal-to-liquid technology | turning coal into liquid fuel |
| Control Rods | neutron-absorbing material inserted into spaces betwen fuel assemblies in nuclear reactors to regulate fission reaction |
| Energy | the capacity to do work (that is, to change the physical state or motion of an object) |
| Fossil Fuels | petroleum, natural gas, and coal created by geological forces from organic wastes and dead bodiso f formerly living biological organisms |
| Fuel Assembly | a bundle of hollow metal rods containing uranium oxide pellets; used to fuel a nuclear reactor |
| High-level waste repository | a place where intensely radioactive wastes can be buried and remain unexposed to groudwater and earthquakes for tens of thousands of years |
| Integrated Gasification Combined Cycle | a power plant that heats fuel to high temperatures and pressures in the presence of 96 percent oxygen. Hydrogen is separted from hydrocarbons and separated from CO2 and other contaminants. The hydrogen isburnedin a gas turbine and surplusheatdrivesturbine |
| Joule | a unit of energy. One joule is the energy expended in 1 second by a current of 1 amp flowing through a resistane of 1 ohm |
| Methane Hydrate | small bubbles or individual molecules of methan (natural gas) trapped in a crystalline matrix of frozen water |
| Monitored, retrievable storage | holding wastes in underground mines or secure surface facilities such as dry casks where they can be watched and repackaged, if necessary |
| newton | |
| Nuclear Fission | the radioactive decay process in which isotopes split apart to create two smaller atoms |
| Oil Shale | a fine-grained sedimentary rock rich in solid organic material called kerogen. When heated, the kerogen liquefies to produce a fluid petroleum fuel |
| Power | the rate of energy delivery; measured in horsepower or watts |
| Proven Reserves | those that have been thoroughly mapped and are economical to recover at current prices with available technology |
| Tar Sands | sand deposits containing petroleum or tar |
| Work | the application of force through a distance; requires energy input |
