We see fuel shipped to nuclear reactors in what are called fuel bundles. These fuel bundles are comprised of a number of fuel elements, which can be round rods or flat plates. The individual elements are welded up to make the fuel bundle. The fuel bundle is packed in a very heavy and heavily armored container, and that fuel bundle is ready to be loaded into the core of a reactor during fueling.
The fuel inside the fuel elements is usually uranium oxide (UO2), with U-235 as the primary isotope. This uranium has had its light isotope content lifted above what it would be naturally by a process called enrichment. The enriched uranium is oxidized to be turned into fuel. (The oxide of uranium will not burn as the pure metal would.)

What is a sentence for energy?
Nuclear energy is obtained by the fissioning of nuclei of uranium235, in a controlled chain reaction in a nuclear reactor, which produces heat that can be converted to electricity by normal power plant methods.
What is one bad use of uranium235?
can cause lung cancer
How does scientists create nuclear fuels?
Uranium ore (usually black oxide) is mined.Uranium ore is shipped to Mill.Mill separates Uranium from ore and converts black oxide to yellow oxide (yellowcake).Yellowcake is shipped to Enrichment plant.Preprocessing plant converts yellowcake to Uranium Hexafluoride (the only Uranium compound that is a gas near room temperature, but also corrosive to almost every metal except nickel and explosive in contact with either water or oil!!!)Enrichment plant enriches the Uranium in the Uranium Hexafluoride gas from 0.72% Uranium-235 (natural level) to 3% Uranium-235 (power reactor fuel level)Postprocessing plant converts enriched Uranium Hexafluoride to enriched yellowcake.Yellowcake is shipped to fuel pellet Canning plant.Canning plant cans yellowcake in Zirconium alloy fuel pellet cans.Fuel pellets are shipped to fuel rod Assembly plant.Assembly plant inserts fuel pellets into steel fuel rod tubes.Fuel rods are shipped to Reactor.Fuel rods are inserted in Reactor as needed.This is the basic outline from mine to a water moderated & cooled reactor. There are many additional minor steps along the way. For other reactor designs (e.g. metal cooled fast breeder reactor, gas cooled high temperature graphite moderated pebble bed reactor, liquid metal fueled reactor) several of the basic steps themselves will have to change.
What is true about the fission of uranium235?
The reaction produces more neutrons than were needed to start it.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What is the form of nuclear energy?
Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
What rhymes with factor?

Are there more are there one type of nuclear reactor?
the boiling water reactor, pressurized water reactor, and the LMFB reactor
What are a completely mixed flow reactor and its concentration characterisrtics?
a completely mixed reactor. the concentration in the reactor is the same that flows our of the reactor
How big is the reactor vessel in a boiling water reactor?
A reactor vessel in a boiling water reactor is approximately 300 tons.
What is nuclear reactor kinetics?
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
What is a reactor used for in welders?
Not a nuclear reactor!
