Radioactive Wastes

Disposal of Radioactive Wastes

Almost all major nuclear operations produce residues containing radioactive materials; in reactor operations, for example, the fission products, new elements (such as plutonium) produced by neutron irradiation and the unfissioned nuclear fuel are all radioactive. Some of this material can be put to further use: useful radioisotopes, for instance, can be extracted from the fission products and p...

Downblending Contaminated Radioactive Wastes

Dilution is the mixing of radioactive waste with non-radioactive material, whereas downblending is the mixing of high-level radioactive waste with low-level radioactive waste. These processes have been applied predominantly at nuclear sites as part of the decontamination procedures for the disposal of blended wastes in licensed facilities. Proper health and safety assessments should be carried ...

The Management of High-Level Radioactive Wastes

The terms, low-level, mediumor intermediate-level and high-level radioactive wastes are being universally used, implying different concentrations of radionuclides or radioactivity in the waste. These terms originated in the 1950's for operational purposes and generally indicated how the waste was being handled or treated and what was being done with it under the local operating conditions at a ...

Liquid Radioactive Wastes Treatment: A Review

Radioactive wastes are generated during nuclear fuel cycle operation, production and application of radioisotope in medicine, industry, research, and agriculture, and as a byproduct of natural resource exploitation, which includes mining and processing of ores, combustion of fossil fuels, or production of natural gas and oil. To ensure the protection of human health and the environment from the...
