Glossary
Plutonium: the chemical element of atomic number 94, a dense silvery radioactive metal of the actinide series, used as a fuel in nuclear reactors and as an explosive in nuclear fission weapons. Plutonium only occurs in trace amounts in nature but is manufactured in nuclear reactors from uranium-238.
Uranium: the chemical element of atomic number 92, a gray, dense radioactive metal used as a fuel in nuclear reactors.
Nucleus: the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
Neutron: a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
Heavy Water: water in which the hydrogen in the molecules is partly or wholly replaced by the isotope deuterium, used especially as a moderator in nuclear reactors
Kilogram: the SI unit of mass, equivalent to the international standard kept at Sèvres near Paris (approximately 2.205 lb).
