If the water coolant level drops enough to expose fuel rods, the surface of those rods can then get hotter than the boiling point of water. The fuel pellets inside the rods are clad in zirconium metal, which when it gets hot enough will decompose water (both as liquid and as steam) into hydrogen and oxygen. As the hydrogen is lighter than air it accumulates as a "bubble" in the top of the reactor vessel.
Note: early reactors clad the fuel pellets with aluminum, but it decomposes water at a much lower temperature than does zirconium.

What fusion in stars occurs to create the element helium?
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
What kind of change is hydrogen to helium?
nuclear fusion of hydrogen to form helium
How do you find elements of nuclear fusion?
In nuclear Hydrogen bomb is based on the principle of fusion. In fusion two hydrogen fuses to form one helium.
How is helium formed from hydrogen?
It's called the proton-proton cycle. It's the source of the sun's energy. Also called nuclear fusion.
How can you combine 2 hydrogen atoms to form a helium atom?
Nuclear fusion. - - - - - There's three kinds of hydrogen: protium, deuterium and tritium. Protium is the vast majority of all hydrogen, and it has no neutrons. Deuterium has one neutron and tritium has two. With no neutrons you can't produce an atom with more than one proton, because they repel each other without the moderating force neutrons give. In the conditions of the sun, neutrons can be made; therefore, you can make helium out of protium. (But it'll take four atoms of protium to give one of helium, two of which will become neutrons.) The fusion reactors we have on earth require deuterium and tritium to work. On earth or in space, sticking two hydrogen atoms in close proximity gives an H2 molecule, not a He atom.
Form of matter found in lighting bolts nuclear reactors and stars?
form of matter found in lightning bolts, nuclear reactors, and stars?
A form of pollution associated with nuclear power reactors is?
heat
What is the Form of matter found in lighting bolts nuclear reactors and stars?
Lightning bolts are discharges of electricity. Nuclear reactors contain mainly uranium. Stars contain light elements undergoing nuclear fusion. I don't see any common form of matter.Actually, plasma is found in all of them.
What metal is mainly used to fuel nuclear reactors?
Uranium, but it is actually in oxide form, UO2
What fusion in stars occurs to create the element helium?
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
Is fission reaction chemical reaction?
A fission reaction is a chemical reaction wherein the atom gets split to generate energy. The most commonly used controlled form of this is in splitting Hydrogen for producing energy in nuclear reactors. It is also used in weaponry such as Hydrogen Bombs which have much greater power than in nuclear fusion reactions.
What kind of change is hydrogen to helium?
nuclear fusion of hydrogen to form helium
What is an hydrogen bomb?
A hydrogen bomb is a nuclear weapon that releases atomic energy by union of light(hydrogen) nuclear at high temperatures to form helium.
Why do nuclear reactors use coolants?
Nuclear reactors use coolants (a main coolant) to keep form overheating, of course. They are also used totransfer the thermal energy (heat) generated by a reactor to the steam generating units.
Why are nuclear reactors so reliable?
Because they can be used to exterminate tiny kittens and some form of Arabs
What prosses causes atars to give off heat and linght?
Nuclear Fission and Nuclear Fusion are the reactions which enable stars to give off heat and light. Nuclear Fission: When a nucleus of an atom of heavy element splits is called nuclear fission. The principle used in Nuclear reactors. Uranium 255 is broken down to form krypton and lead. Nuclear Fusion: When nuclei of 2 or more light atoms fuse or join together is called nuclear fusion. The principle used in Hydrogen Bomb. Two Hydrogen atoms fuse together to form a Helium atom.
What are graphite's uses?
Graphite is a pure form of coal or carbon. It is a good conductor of heat and electrcity. It is used as a neutron moderator in nuclear reactors of type Gas Cooled reactors.
