In this study application of modified CANDLE burn-up scheme for medium-sized (800-1500 MWt) long-life Pb-Bi cooled fast reactors with natural uranium as fuel cycle input has been performed. The reactor cores are subdivided into several parts with equal volume in the axial directions. The natural uranium is initially put in region 1, after one cycle of 10 years of burn-up it is shifted to region 2, and 10 years after that it is shifted to region 3. This concept is applied to all regions, i.e. shifted the core of I-th region into I+1 region after the end of 10 years burn-up cycle. The first region 1 is filled by fresh natural uranium fuel. The core radial size is optimised to give maximum power density around 400 W/cc.

Mining Waste Incineration in Greenland - Case Study
Location: GreenlandClients: Explorative Mining TeamsWaste Type: Camp wasteSolution Supplied: i8-20s Minerals such as Uranium and Titanium are now being mined in Greenland, a previously untapped source of minerals. Inciner8 have been on hand to provide essential waste solutions that can be moved when not in use to meet local legislation.Due to these seasonal conditions in Greenland, the project teams have a limited amount of time in which they can be operational, INCINER8 can ship and install large scale...
Mining Waste in Greenland - Mining Waste Management & Incineration Solutions
As more and more mining operations open up the unexplored frontiers of Greenland’s rugged landscape, the demand for a safe and effective way to dispose of mining waste is increasing. At Inciner8, we’re helping to lead the way in pioneering incineration solutions.The growth of mining in Greenland When most people think about mining, images of coal mines or off-shore oil rigs spring to mind, or large diamond mines in Sub-Sahara Africa perhaps. But increasingly, Greenland is the epicentre of the latest...
3 Water Utilities that Lowered their Arsenic Levels with AdEdge
Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the U.S. Environmental Protection Agency (EPA) has a maximum contaminant level standard of 0.01 mg/L. Throughout the country, municipalities are looking for ways to...
Adsorption and desorption of uranium(VI) onto humic acids derived from uranium-enriched lignites
Humic acids (HAs) were extracted and characterized from three kinds of uranium-enriched lignites from Yunnan province, China. Batch experiments were used to study the adsorption and desorption behavior of uranium (VI) onto these HAs and a commercial HA. The results showed that the optimum pH level at which all the HAs adsorbed uranium(VI) ranged from 5 to 8. The high uranium content of the HAs was released into the solution at the pH values between 1 and 3; when the HA dosage was 2.5 g L−1, the maximum concentratio...
