Radioactive Waste

Radioactive waste is waste that contains radioactive materials. This can be caused by nuclear fission, nuclear medicine, radiography, and other sources. There are very strict rules about the storage and disposal of radioactive waste.

Fission creates large amounts of radioactive waste?

The high level waste, which is the dangerous part, is contained in the spent fuel, so it has the same volume as the fuel rods, unless they are processed. The actual amount is manageable, it is the high activity that is the problem for disposal.

Where is most of high level waste stored in the US?

in on site spent fuel rod "Swimming Pools". once they are full they are full and the reactor will be forced to shut down.

What is the nuclear pore used for?

The nuclear pores are tiny holes in the the nuclear membrane surrounding the nucleus of a cell, which allow the movement of solluable materials through the nuclear membrane, in and out of the nucleus.

Is the tiberium crystal real or fictional?

its just a fictional element in command and conquesr no such thing/element exists in real life dear..

What is the percentage of nuclear waste from nuclear power plants?

All the significant high level waste is contained in the spent fuel, and will stay there when the fuel is stored after unloading, unless the fuel is taken to a plant designed for dismantling and separating it. This is done in the UK and France, possibly Russia, I'm not sure about that, but not in the US, not for commercial reactors anyway. The fissile part of the new fuel is about 4 percent U-235 and it is discharged with about 1 percent remaining so that difference determines the percentage of fission products in the discharged fuel. It will also contain plutonium which has been formed from the U-238 which forms 96 percent of the new fuel, but again a lot of the fissile plutonium formed will have been burned up during reactor operation. So the percentage by weight is a fairly small part of the spent fuel, most of which will be U-238, which if separated out is fairly inocuous and could be used in breeder reactors if we had any.

How is the largest amount of nuclear waste categorized?

They are categorized according to:

  • Physical form (solid, liquid, or gaseous)
  • radioactivity level (high, intermediate, low)

Does fusion produce radioactive waste?

No. The products of nuclear fusion are not radioactive.

Why not dispose of nuclear waste in the sun?

One reason is that it is incredibly expensive to get things to go into space. Every pound you send into space costs a couple grand. There are probably more reasons, but this is the main one.

Why can't nuclear waste be buried in uranium mines?

because it's a mine and they are still mining i think plus you need 1/2 an inch of lead to protect it. Also you need lots of room

Is nuclear waste stored in Colorado?

There are no nuclear power plants in Colorado. The only source of waste might be from a small teaching or medical isotope reactor, I have no information on this.

What are two isotopes that were released in the chernobyl accident?

Actually there were hundreds of isotopes released, about the same mix (any isotope having mass numbers from 72 to 161) as one would get from any fission bomb but in much larger quantity as the reactor core is much larger than any fission bomb core.

A few of the isotopes and some effects (where known) are:

  • selenium-75
  • krypton-85
  • strontium-90, replaces calcium in bones causing weakening and/or cancer
  • zirconium-95
  • niobium-95
  • xenon-127
  • telerium-132
  • xenon-133
  • iodine-131, concentrates in thyroid killing it and/or causing cancer
  • cesium-134, replaces potassium in the body causing widespread damage
  • cesium-137, replaces potassium in the body causing widespread damage
  • lanthanum-140
  • cerium-144
  • promethium-145
  • promethium-147
  • etc.
In addition to fission product isotopes above, many isotopes of the uranium fuel and various transuranic elements were released.

What is the problem with disposing of radioactive wastes is that they have a long what?

Radioactive substances have half-lives. This is because the isotope constantly is changing from the radioactive isotope to a daughter element. For example, eventually, when uranium's radioactivity is gone, it becomes lead. After one half life of a radioactive substance, only 50% of that substance is still radioactive. Therefore, after one half-life, a piece of uranium is 50% lead and therefore %50 less radioactive. After another half-life, it has 25% of the original radioactivity, and 75% of the original uranium has become lead. This is the problem with radioactive wastes. It takes many years just for one half lives for some substances, such as uranium. Because radioactivity is harmful, those substances have to be stored until they are no longer radioactive. So, in short, the problem with disposing of radioactive wastes is that they have long half-lives. (although this is not true with ALL substances because some have short half-lives, but, in general, radioactive substances have long half-lives.

Why are current methods of nuclear waste disposal inadequate?

It is not true. Currently; there are well established methods and approaches to deal with radioactive waste based on the waste form (solid, liquid. gaseous) and the radioactivity level (low, intermediate, high). There are well practiced regulations and laws to deal with radioactive waste to protect the public and workers from being exposed to any unjustified hazards or radiations from radioactive waste.

What is the chemistry in the disposal of nuclear waste?

The disposal of nuclear waste typically involves encapsulating the waste in materials like glass or ceramic to prevent the release of radioactive materials. This process is aimed at minimizing the long-term impact of radioactive waste on the environment and human health. Specialized facilities, such as deep geological repositories, are used for the final disposal of nuclear waste.

What are the benefits of disposing nuclear waste?

Since it is highly reactive, you can keep it away from humans and vice versa so that it wont harm humans in any shape way or form.

How are radioactive substances used in hospitals?

they are used as:

  • radioactive tracers to be injected to the patient for later on photographing for diagnosis purposes.
  • as enclosed and shielded radioactive source and the patient is exposed to its radiation for treatment and/or diagnosis.

Determination of the location of stable sites for nuclear wastes is based upon the theory?

To prevent damage, the NRC has found means of "controlling" radiation. Materials with high levels of radiation are shipped from the nuclear generating stations, where they were created as a by-product, to reprocessing plants. The transportation process itself could be hazardous. Here they are concentrated and stored temporarily in underground tanks. Because long-term tank storage is not as safe as desired, these materials are changed from liquid to solid form. The solids are then sent to a federal storage site, such as an abandoned salt mine, for permanent storage. Salt mines are considered to be excellent sites because they are currently geologically stable. They are not able to be penetrated by water, and not connected to underground water sources. The assessment of stability is based on the assumption of uniformitarian geology.

The process of nuclear change in an atom of radioactive material is called what?

I'm not sure if there is one word to describe different processes. Thus there can be radioactive decay into a different isotope (alpha or beta decay), gamma ray emission which means a change in energy state of the nucleus, nuclear fission as in U-235 in a reactor, and neutron induced change such as U-238 absorbing a neutron becoming Pu-239.
