27 Facts About Nuclear waste

Radioactive Nuclear waste is a type of hazardous Nuclear waste that contains radioactive material.

Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, rare-earth mining, and nuclear weapons reprocessing.

The storage and disposal of radioactive Nuclear waste is regulated by government agencies in order to protect human health and the environment.

The Nuclear waste is subsequently converted into a glass-like ceramic for storage in a deep geological repository.

Time radioactive Nuclear waste must be stored for depends on the type of Nuclear waste and radioactive isotopes it contains.

Short-term approaches to radioactive Nuclear waste storage have been segregation and storage on the surface or near-surface.

All radionuclides contained in the Nuclear waste have a half-life — the time it takes for half of the atoms to decay into another nuclide.

High-level Nuclear waste is full of highly radioactive fission products, most of which are relatively short-lived.

Radioactive medical Nuclear waste tends to contain beta particle and gamma ray emitters.

Low-level waste is generated from hospitals and industry, as well as the nuclear fuel cycle.

Low-level Nuclear waste is divided into four classes: class A, class B, class C, and Greater Than Class C .

Intermediate-level Nuclear waste contains higher amounts of radioactivity compared to low-level Nuclear waste.

High-level waste is produced by nuclear reactors and the reprocessing of nuclear fuel.

Ongoing controversy over high-level radioactive waste disposal is a major constraint on the nuclear power's global expansion.

Under U S law, transuranic waste is further categorized into "contact-handled" and "remote-handled" on the basis of the radiation dose rate measured at the surface of the waste container.

Future way to reduce Nuclear waste accumulation is to phase out current reactors in favor of Generation IV reactors, which output less Nuclear waste per power generated.

Nuclear waste requires sophisticated treatment and management to successfully isolate it from interacting with the biosphere.

Long-term storage of radioactive Nuclear waste requires the stabilization of the Nuclear waste into a form that will neither react nor degrade for extended periods.

The resulting glass is a new substance in which the Nuclear waste products are bonded into the glass matrix when it solidifies.

The properties of phosphates, particularly ceramic phosphates, of stability over a wide pH range, low porosity, and minimization of secondary Nuclear waste introduces possibilities for new Nuclear waste immobilization techniques.

Process of selecting appropriate deep final repositories for high-level Nuclear waste and spent fuel is underway in several countries with the first expected to be commissioned sometime after 2010.

Ocean floor disposal of radioactive Nuclear waste has been suggested by the finding that deep waters in the North Atlantic Ocean do not present an exchange with shallow waters for about 140 years based on oxygen content data recorded over a period of 25 years.

Management of radioactive waste and its safe and secure disposal is a necessary step in the lifecycle of all applications of nuclear science and technology .

Radioactive waste is therefore generated in practically every country, the largest contribution coming from the nuclear energy lifecycle in countries operating nuclear power plants.

The radioactivity of high-level radioactive Nuclear waste affords proliferation resistance to plutonium placed in the periphery of the repository or the deepest portion of a borehole.
