“…However, the project did not result in actually building and operating an HTGR. In the case of energy neutral mineral processing, though it may be realized, HTGRs could be the first choice over other emerging HTR technology [131][132][133], such as the compact high temperature reactor (CHTR) [134,135], fluoride salt-cooled, high-temperature reactor (FHR) [136][137][138][139], gas-cooled fast reactor (GFR) [140][141][142], lead-cooled fast reactor (LFR) [143][144][145], molten salt reactor (MSR) [146] and others that may deliver process heat at temperatures higher than or equal to 600 °C. Five countries: Great Britain, the U.S., Germany, Japan and China have experience with operating and thus licensing HTGRs.…”

A number of primary ores such as phosphate rock, gold-, copper-and rare earth ores contain considerable amounts of accompanying uranium and other critical materials. Energy neutral mineral processing is the extraction of unconventional uranium during primary ore processing to use it, after enrichment and fuel production, to generate greenhouse gas lean energy in a nuclear reactor. Energy neutrality is reached if the energy produced from the extracted uranium is equal to or larger than the energy required for primary ore processing, uranium extraction, -conversion, -enrichment and -fuel production. This work discusses the sustainability of energy neutral mineral processing and provides an overview of the current progress of a multinational research project on that topic conducted under the umbrella of the International Atomic Energy Agency.

“…The selection of this reactor was based on its excellent potential for long-term sustainability, in terms of the use of uranium and of minimizing waste through reprocessing and fission of long-lived actinides [14,15]. In terms of non-proliferation, the objective of high burn-up together with actinide recycling results in spent fuel that is unattractive for handling.…”

“…This paper studies the fracture resistance of the 14Cr ODS steel after relatively short exposure to elevated temperature gas environments. The exposure condition is selected as 720 • C in helium gas, based on the reference cooling condition of the US Dual Coolant (He and PbLi) Lead Lithium (DCLL) test blanket module concept [14] and the close to gas fast reactor (GFR) concept [15]. The second environment, the normal air, is chosen to simulate exposure to an accident situation.…”

This paper studies the impact fracture behavior of the 14%Cr Oxide Dispersion Strengthened (ODS) steel (ODM401) after high temperature exposures in helium and air in comparison to the as-received state. A steel bar was produced by mechanical alloying and hot-extrusion at 1150 • C. Further, it was cut into small specimens, which were consequently exposed to air or 99.9% helium in a furnace at 720 • C for 500 h. Impact energy transition curves are shifted towards higher temperatures after the gas exposures. The transition temperatures of the exposed states significantly increase in comparison to the as-received steel by about 40 • C in He and 60 • C in the air. Differences are discussed in terms of microstructure, surface and subsurface Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) observations. The embrittlement was explained as temperature and environmental effects resulting in a decrease of dislocation level, slight change of the particle composition and interface/grain boundary segregations, which consequently affected the nucleation of voids leading to the ductile fracture.
