Solutions for Nuclear WasteA lot of things are currently done with nuclear "waste". First it should be understood that the majority of what people consider waste is actually "spent nuclear fuel". This is fuel that comes out of a reactor after it has been used for electricity production. What most people don't know is that although the fuel isn't fit for further use in a reactor, it contains a great deal of uranium and other isotopes with a very high energy content. The reason it is referred to as waste is because we (the U.S.) currently don't have a way to utilize this material. This is due to a ban on reprocessing in our country. Through reprocessing we can separate out the nuclear material that can still be used as fuel from that which can't. Around 95% of the spent fuel is actually uranium that can be reprocessed.

As for disposal, several methods exist to keep nuclear material away from humans and vice versa. Geologic disposal (such as the Yucca Mountain facility), transmutation (a process wherein radioactive material is changed into more stable forms), and reuse of fuel material in advanced reactor designs. I'm only aware of storage currently being used, transmutation and advanced reactors are currently under development around the globe.

A great deal of R&D and policy decisions are needed before the nuclear waste issue can be completely solved. The R&D work is being carried out at universities and laboratories around the world and hopefully the policy-makers will have come to their senses before it is too late.

One possible solution to the problem would be to re-enrich the uranium in the spent fuel and develop advanced reactor fuels to burn long-lived radioisotopes (such as transuranic elements). If these can be removed from the waste, the time frame for required observation of geologically disposed waste would be reduced to a few hundred years; a much more manageable scale than the current requirement of thousands of years. Not only would this reduce the long-term waste liability of these materials, it would also provide a new energy source from the spent fuel.

Here are more opinions and answers from other FAQ Farmers:

  • There are no good solutions. Right now the government is planning on burrying our nuclear waste in a saced native American mountain where it can leach into the ground eventually. Also, this option would only get rid of some of the waste. We need to start investing in renuable energy like wind and solar energy.
  • Currently nuclear waste goes into the ocean in areas not controlled by any particular country [over 12 miles from land, I can't remember the actual distance].

Why isn't nuclear waste have its radiation used for solar power?

Because nuclear waste doesn't give off the same radiation as the sun.


Why is nuclear waste renewable?

Nuclear waste is NOT renewable. It is typically buried and sealed off because of its non-usability and the radiation damage that can afflict people from being in the vicinity of nuclear waste.


Why is the waste produced from a nuclear reaction harmful?

Because it emits ionising radiation


What does nuclear waste do to you?

The nuclear waste gives off radiation. That radiation in large enough doses changes DNA in cells. When the DNA changes sometimes the cells can become cancerous. In even higher doses the cells will die.


Is it safe to go near Nuclear Waste?

No. It emits radiation and is very harmfull without a proper Radiation Protective equipment


Why are nuclear waste at times said to be a problem which is too complicated to solve?

Nuclear wastes are sometimes said to be a problem too difficult to solve because the waste stays radioactive for so long. The only thing that gets rid of nuclear waste is time.


How does nuclear energy affect the human?

I assume you mean how does nuclear radiation affect the human body. Nuclear energy as used in nuclear power plants has no effect normally as the radiation is well contained. However if you want to know about the effect of radiation on the body, see the link below


What does Yucca Mountain have to do with nuclear radiation?

Yucca Mountain is a proposed repository site for storing high-level nuclear waste in the United States. The site was chosen for its geologic stability and isolation to prevent radiation from reaching the environment. If approved and constructed, Yucca Mountain would be used to store spent nuclear fuel and other radioactive waste generated by nuclear power plants.


What are some surrounding problems with nuclear power producing electrical energy?

Some surrounding problems with nuclear power include the risk of accidents and radioactive waste disposal. Accidents like meltdowns can have severe consequences for human health and the environment. Additionally, finding long-term solutions for storing radioactive waste safely is a challenge.


What does nuclear disaster mean?

it means that either a nuclear rocket or a nuclear lab has exploded letting out nuclear waste and radiation which means the city would have to be evacuated until they are out of the nuclear radation zone.


What happens with the waste from nuclear power?

The waste from nuclear power, known as nuclear waste, is typically stored in secure containers at nuclear power plants or in underground repositories. Different countries have different strategies for managing and disposing of nuclear waste, with some exploring options for recycling or reprocessing it to reduce its volume and radioactivity. Long-term solutions for nuclear waste disposal, such as deep geological repositories, are being developed to ensure safe containment for thousands of years.


What is the harmful radiation released by nuclear wastes?

There are various kinds of harmful ionizing radiation. These include alpha, beta, and gamma rays; free neutrons; X-rays; and ultraviolet light. Depending on the specifics of the waste, nuclear waste can emit alpha, beta, and gamma rays, and neutrons.
