What do you know
about chemical reaction that takes place in a nuclear power plant? Yes of
course there will the fission reaction of the uranium to produce power. There
are also the neutron capture, which the two are the main process focuses on.
But do you know there are also the sides dishes that is essentials in
controlling and maintaining the plan? These side reaction are the reaction of
the water chemistry as it being used as a coolant for the reactor pure.
Raw Uranium |
Uranium plays a very important
role in the production of energy through nuclear power. A heavy element located
in the Actinide series it has 92 protons as indicated by its atomic number.
Uranium has many different isotopes; different configurations of protons and
neutrons in its nucleus. Not all of its isotopes are stable. Nuclear Power is
produced when a nucleus absorbs a neutron and splits into two lighter nuclei.
This releases enormous amounts of energy which in turn produces heat. In fact
the Uranium, which is the most common element used to produce nuclear power
today, has an energy content about 3 million times greater than that of fossil
fuel. Nuclear reactors harness the heat which is produced from the energy
released when the atom splits and convert it into electrical energy.
Uranium 239 |
Neutron capture is a term used
for the scenario where a neutron comes close to a nucleus (in this case
uranium) and the nucleus captures it and becomes a different nucleus. In this
case when uranium-238 captures a neutron it becomes uranium-239. After
uranium-239 emits a beta particle (electron) it becomes neptunium-239. Then,
neptunium-239 emits a beta particle and becomes plutonium-239. The plutonium
can also be used as nuclear fuel.
Nuclear Reactor Coolant |
A nuclear reactor coolant is a coolant in a nuclear reactor used to
remove heat from the nuclear reactor core and transfer it to electrical
generators and the environment. Frequently, a chain of two coolant loops are
used because the primary coolant loop takes on short-term radioactivity from the
reactor. Almost all currently operating nuclear power plants are light water
reactors using ordinary water under high pressure as coolant and neutron
moderator. Heavy water reactors use deuterium oxide which has similar
properties to ordinary water but much lower neutron capture, allowing more
thorough moderation. However these water also has it bad effects. The effects
are the corrosion in coolant circuits. Also it does effect on the corrosion of
copper alloys and zirconium at an operating nuclear power plants.
