Transcript of CHEMISTRY TASIA MILLER. Nuclear: operated or powered by atomic energy Waste: to destroy or consume...
Nuclear waste:The material that nuclear fuel becomes after the fuel is used in a reactor.
Nuclear waste is produced from nuclear energy.
Nuclear waste refers to the entire array of radioactive materials created by all aspects of nuclear technology.
Nuclear: operated or powered by atomic energy
Waste: to destroy or consume gradually
Disposal: a disposing of or getting rid of something
Three Types of Nuclear Waste HIGH-LEVEL NUCLEAR WASTE-High-level nuclear
waste is generated by the chemical reprocessing of spent nuclear fuel to recover uranium and/or plutonium.
LOW-LEVEL NUCLEAR WASTE-All radioactive waste other than spent fuel, high-level waste, and transuranic waste is considered to be low-level waste.
TRANSURANIC NUCLEAR WASTE-Transuranic waste is physically similar to low-level waste but is contaminated with transuranic elements to a level requiring geologic disposal.
SPENT NUCLEAR FUEL-
Spent fuel is fuel that has been used in and
then withdrawn
from a nuclear reactor.
The Nuclear fuel cycle
HIGH-LEVEL NUCLEAR WASTE
This type of waste has mostly spent nuclear reactor fuel from commercial power plants and military facilities. So does
reprocessed materials. It can have large amounts of radiation for thousands years. Commercial nuclear power
plants in the United States produce 3,000 tons of high-level waste every year. When high-level waste repositories isn't there, nuclear power plants store their spent fuel rods
in lead-lined conceete pools of water. The pools have spread of gamma radiation by keeping the rods cool.
LOW-LEVEL NUCLEAR WASTE-
Low-Level are not spent fuel, milling tailings, reprocessed materials, or transuranic materials. It has the left over's of
radioactive wastes and materials in power plants, like contaminated reactor water, and wastes created in
medical laboratories, hospitals. This level can be unsafe for more than ten of thousands years.
Most come from reactors, The low-level wastes can be divided into two categories. They are called Fuel wastes and
Nonfuel wastes.
TRANSURANIC NUCLEAR WASTE
Transuranic waste material was made in the United states since 1940. Transuranic means the atoms of man-made
elements that are heavier than uranium. Some Transuranic nuclear waste has organic and inorganic residues or they are enclosed and contaminated cases which radioactive
materials were handled. This nuclear waste has laboratory equipment tainted with radioactive materials, and rags, and tools. Some Transuranic nuclear waste gives high
levels of penetrating radiation. A problem with this nuclear waste is that most of the radioactive elements stay
radioactive for a long time.
EIGHT STEPS OF NECLEAR WASTE DISPOSAL
How radioactive waste is disposed depends on the material's half-life and its level of radioactivity.
Theses are steps for disposing waste:1. Place the waste in a water pool, as a radiation shield to protect workers.2. The fuel dissolves in chemicals to recover unfissioned uranium, then
waste turns into liquid.3. Reprocess the waste for use in nuclear weapons or to reuse in new fuel.4. Reduce storage volume, and then the waste is concentrated by
calcination.5. The waste is bonded into glass or concrete.6. Keep waste from leaking and going into the biosphere. 7. Then they stabilize the waste for later consolidation.8. The acceleration of decay produce products.
How I feel about the process of disposing nuclear waste.
Although I'm not exactly sure about nuclear waste I do know that
Why Nuclear Waste Dangerous
Nuclear waste is very dangerous because,
Nuclear waste is radio active. The atoms it is
made out of breaks down easily. Then it releasing radiation in the form of alpha, beta and gamma
radiation. They are all bad for us to us and other living things. They can
cancer. If they go through the ground into ground
water, it pollutes it. That’s why the workers who
dispose it have to be very careful.
