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 کاملLow-voltage electroosmotic pumps fabricated from track-etched polymer membranes.
Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...
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 ...
متن کاملProton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
