Nuclear: operated or powered by atomic energy Waste: to destroy or consume gradually Disposal: a disposing of or getting rid of something

 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Spent fuel is fuel that has been used in and then withdrawn from a nuclear reactor. The Nuclear fuel cycle

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 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 waste material was made in the United states since 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 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.

SOME PEOPLE FEEL THAT NUCLEAR WASTE SHOULD BE BARRIED.

Although I'm not exactly sure about nuclear waste I do know that

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.
