CANDU burns natural unenriched uranium.
Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
It exists in liquid qualitatively alter the nature of transition.
Around 1500 unstable nuclei (or radioisotopes).
Centrifugal forces at present do not exist in nature. However, the opposite of centrifugal forces, centripetal forces, do exist. Centrifugal forces are used only to explain that centripetal forces need an opposite force to act against it.
Diverse types of waves exist in nature, whether we like it or not. They can be used to transfer both information, and energy.
Uranium exist in nature as minerals and ores; more than 200 uranium minerals are known today.
Uranium is a metal, natural, radioactive. Uranium exist only as minerals in the nature. Soils contain traces of uranium.
Different types of nuclear plants: Pressurised Water Reactor (PWR); Boiling Water Reactor (BWR); Heavy Water Moderated Reactor (CANDU); Advanced Gascooled Reactor (AGR); Fast Breeder Reactor (FBR); Pebble Bed Gascooled Reactor; Water Cooled Graphite Reactor (RBMK). There are other ideas that only exist on paper.
Protactinium exist in minute traces in uranium ores.
Actinium exist in minute traces in uranium and thorium ores.
Uranium - for economical exploitation - exist in mines.But uranium is is a common element in all rocks, all waters, building materials, soils etc.
Natural isotopes of plutonium exist only in traces in uranium ores.
Neptunium exist in nature in: - uranium ores, in extremely traces concentrations - in areas of past nuclear weapons tests
Technetium is an artificial chemical element; only ultratraces exist in nature in uranium ores.
A nuclear reactor is a plant which deliver electricity and (or) heat.The function principle is the release of energy from nuclear fission of fissile materials as the isotope uranium-235.
In the nature uranium exist only as compounds; approx. 200 uranium minerals are known today. In the US: New Mexico, Wyoming, Colorado, Texas, Arizona, and Utah. Canada has even larger supplies.
Plutonium exist in extremely low concentrations in uranium minerals; the chemical form is probably plutonium dioxide or a complex oxide with uranium.
