Boiling water reactor
(BWR) |
A type of fission reactor in which
water surrounds the nuclear fuel core within the reactor. |
|
|
breeder reacting
|
Creating nuclear fuel from a substance that is not fissionable.
|
|
|
control rod
|
Part of a fission reactor that sits betr,r.een the fuel rods and absorb strav neutrons.
|
|
|
electron
|
A negatively charged atomic particle.
|
|
|
half-life
|
The time it takes for half the atoms present in an unstable element to transform into a new element.
|
|
|
isotope
|
One of two or more atoms with the same number of protons but with different numbers of neutrons.
|
|
|
kyoto protocol
|
Thrgets setin1997 by countries wishing to increase capacity while reducing carbon dioxide (CO.) emissions.
|
|
|
neutron
|
an uncharged atomic particle
|
|
|
nuclear fission
|
The process of splitting a larger atom to produce two smaller atoms and a tremendous amount of energy.
|
|
|
nuclear fusion
|
The combining of two nuclei into a larger nucleus. The large nucleus weighs less than the two smaller nuclei that formed it.
|
|
|
Nuclear waste fund
|
A multibillion-dollar fund used for the development of a permanent nuclear waste disposal site
|
|
|
Nuclear waste policy act
|
An acl passed by Congress lrl.1982 promising that the federal government is to take nuclear waste from the utilities for permanent storage.
|
|
|
nucleus
|
The center portion of an atom containing the protons and neutrons.
|
|
|
plasma
|
Ionized gas with an equal number of positive and negative charges.
|
|
|
plutonium 239 (Pu-239)
|
A fissionable fuel created from uranium 238 (U238)by a breeder reactor.
|
|
|
pressurized water reactor (PWR)
|
A reactor that works similarly to aboiling water reactor (BWR), except it makes use of a heat exchanger known as a steam generator.
|
|
|
primary loop
|
The part of a pressurized water reactor (PWR) in which the water is heated. It surrounds the reactor core.
|
|
|
proliferation
|
The use of by-products of nuclear power for the production of nuclear weaPons.
|
|
|
proton
|
A positively charged atomic particle
|
|
|
radioactivity
|
A property of some atoms, such as those of uranium decay, in which they give off atomic particles. The particles emitted are harmful to humans and other living things.
|
|
|
secondary loop
|
The part of a pressurized water reactor (PWR)in which steam is created.
|
|
|
shipping cask
|
a container designed to ship spent fuel from one facility to another
|
|
|
three mile island (TMI) accident
|
A nuclear disaster occurring in7979 near Harrisburg, Pennsylvania. The Unit 2 reactor reached excessir.ely high temperatures through a series of faulty readings and operator errors.
|
|
|
uranium 235 (U235)
|
An element whose atoms can be split more easily than most others, making it suitable for refining into nuclear fuel.
|
|
|
uranium 238 (U238)
|
Atype of uranium that is a nonfissionable element. About99'h of all uranium mined is this type.
|
|
|
yucca mountain storage facility
|
A govemmentowned facility in southern Nevada that is a planned site for permanent storage of nuclear waste.
