NUCLEAR WASTE DISPOSAL

CHEMISTRYTASIA MILLER

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then withdrawn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.

How is nuclear waste created???

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.

SHOULD NUCLEAR WASTE BE BURIED?

SOME PEOPLE FEEL THAT NUCLEAR WASTE SHOULD BE BARRIED.

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.
