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...
متن کاملDisposal 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...
متن کاملDownblending 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 ...
متن کاملTreatment of Radioactive Wastes Using Liquid-liquid Extraction Technologies-fears, Facts, and Issues
Liquid-Liquid Extraction (LLE) technologies have been extensively used in the nuclear industry worldwide since the 1940’s for the recovery and purification of uranium and plutonium. These and related LLE technologies continue to be successfully utilized outside of the U.S., but their use for nuclear applications in the U.S. has been essentially discontinued. Numerous LLE technologies have been ...
متن کاملThe 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 ...
