The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...

Liquid radioactive waste is a common by-product when using radioactive isotopes in research and medicine. Efficient remediation of such liquid waste is crucial for increasing safety during the necessary storage of the material. Herein, we present a novel Gum Karaya stabilized magnetite for the efficient removal of radioactive phosphorus (32)P from liquid radioactive waste. This environmentally ...

Pathology, microbiology, blood bank and other diagnostic laboratories generate sizable amount of biomedical waste (BMW). The audit of the BMW is required for planning proper strategies. The audit in our laboratory revealed 8 kgs anatomical waste, 600 kgs microbiology waste, 220 kgs waste sharps, 15 kgs soiled waste, 111 kgs solid waste, 480 litres liquid waste along with 33,000 litres per month...

A preliminary study, which establishes the treatment methodology of liquid waste containing sludge and uranium in the lagoon of the conversion facility has been performed. Properties of the liquid waste such as initial water content, density and radiochemical composition were obtained by analyzing the samples taken from the lagoon. In order to minimize the secondary waste resulting from treatme...

Heavy ion beam driven inertial fusion energy (IFE) power plants employ liquid wall materials to protect the structure against the energetic x-rays, ions, and debris emitted from the target following each shot. The objective of this assessment is to identify the radiological issues of the candidate liquid wall materials (Pb, LiPb, Sn, and Flibe) using the ARIES-IFE radiation chamber environment....

waste low density polyethylenes (ldpe) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. the effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. the effect of catalyst o...

Five steroidal sapogenins (tigogenin, neotigogenina, hecogenin, gloriogenin, and dehydrohecogenin) were characterised by gas chromatography coupled with mass spectrometry (GC-MS) from a hydrolysed extract of sisal waste. In addition, pure hecogenin, an important raw material for the pharmaceutical industry, was obtained from this waste by selective liquid-liquid extraction of saponins with only...
