Sulfuric acid digestion and water leaching. Another way to dissolve the metals present in a solid matrix is the acid digestion process. According to Vijayalakshmi et al. (), more than 98% of rare earth was recovery from xenotime concentrate using digestion with sulfuric acid. lactic acid production and accumulation during anaerobic digestion of municipal solid waste (MSW) leachate. production of lactic acid in the process. There have been very Radioactive Waste.
In J. Davidovits’ book, Geopolymer Chemistry & Applications, Chapter 10 is dedicated to Rock-based Geopolymer cements. The project seek to manufacture economical geopolymeric cements primarily for the long-term containment of hazardous and toxic wastes and for restoring sites highly contaminated with uranium mining waste (the WISMUT sites in. The following conclusions resulted from operation of Radioactive Acid Digestion Test Unit (RADTU) for processing transuranic waste: (1) the acid digestion process can be safely and efficiently operated for radioactive waste treatment.;.
Abstract. These practices cover three standard technique for dissolving glass samples containing radioactive, nuclear, and mixed wastes. These techniques used together or independently will produce solutions that can be analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS.

Conference Lerch, R E ; Allen, C R ; Blasewitz, A G. Acid digestion has been developed at the Hanford Engineering Development Laboratory (HEDL) in Richland, Washington to reduce the volume of combustible nuclear waste materials, while converting them to an inert, noncombustible residue.
The Acid digestion process for radioactive waste: proceedings of a seminar organised under the R & D Programme of the European Communities on Radioactive Waste Management and Storage, held at the Central Bureau for Nuclear Measurements, Geel, Belgium, 28 September The Radioactive Acid Digestion Test Unit (RADTU) was constructed at the Hanford Site, Richland, WA to demonstrate application of the acid digestion process for treating combustible transuranic wastes and scrap materials.
Using its original tray digester vessel, RADTU recently completed a six-month campaign of processing potentially contaminated non-glovebox wastes from a Hanford plutonium. The following conclusions resulted from operation of Radioactive Acid Digestion Test Unit (RADTU) for processing transuranic waste: (1) the acid digestion process can be safely and efficiently.

The acid digestion process has been developed and demonstrated on an engineering scale in several countries and appears to be especially applicable to treatment of combustible wastes containing high levels of transuranic contamination, where there is potential for recovering the transuranic radionuclides.
In this process dry cement and a disposable mixing weight are placed in a L drum, followed by the waste and any additional chemicals. The drum is then capped prior to end over end tumbling.
For this system, cap removal, filling, cap replacement and mixing is an. Reports Series and Safety Series documents on radioactive waste management over nearly three decades. These documents have served Member States presenting basic reference material and comprehensive surveys of the 'state-of-the-art' technologies applied to radioactive waste management.
The need for assistance in specific waste management. Large quantities of radioactive waste, with varying characteristics, are generated from the operation and maintenance of nuclear power plants, the nuclear fuel cycle facilities, research laboratories and.

Radiological impact assessment for workers on treatment of radioactive acid digestion, (2) wet oxidation, (3) molten salt oxidation, (4) electrochemical selectively separated from the spent resin while minimising secondary waste.

There are a number of liquid processes and waste streams at nuclear facilities (i.e. nuclear power plants, fuel reprocessing plants, nuclear research centres, etc.) that require treatment for process chemistry control reasons and/or the removal of.
WASTE PROCESSING AND HANDLING. Waste processing and handling are key concerns as a hazardous waste begins its journey from the generator site to a secure long-term storage facility.
Ideally, the waste can be stabilized, detoxified, or somehow rendered harmless in a treatment process similar to the following. Chemical Stabilization/Fixation. A new collaborative research project for systematic treatments of radioactive liquid wastes containing various reagents generating in nuclear facilities was started from initiated by Japan Atomic Energy Agency.
The project was named as STRAD (Systematic Treatments of RAdioactive liquid wastes for Decommissioning) project. COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.
Sulphuric acid digestion process is used to digest lanthanide concentrate at °C for hours in a stirred reactor.
During the digestion most of Th, rare earth elements and U go into the solution with sulfate and phosphate anions. Because of the chemical similarity between thorium and lanthanides cations in solution selective precipitation is.
Developed and demonstrated by Principal Investigators at the DOE’s Savannah River Site (SRS), Acid Digestion is an oxidative destruction technology for organic constituents of mixed waste. In the Acid Digestion Process waste is fed into a reaction or oxidation vessel containing nitric acid in a phosphoric acid carrier solution.
