“…6) became the EURATOM Consortium's (EVOL's) "reference" MSR. 19 While most of the previous studies of fast-spectrum MSRs had assumed a chloride 20 -based solvent salt in order to facilitate Pu breeding [11], fertile-free TRU burning, or U-supported TRU burning [12], EVOL's leadership assumed a somewhat less fast fluoride salt-based system in order to capitalize upon ORNL's extensive materials science and fuel salt chemistry experience [13].…”

“…Unfortunately, it was subsequently essentially forgotten until the EVOL's MSR researchers decided to resurrect it. 20 All else being equal, a chloride-based MSR is "faster" than its fluoride analog because the halide atoms comprising~two-thirds of those present in either of their salt streams are heavier. 21 "Durability" because the blanket salt would intercept the fast-moving neutrons that would eventually damage the reference MSFR's axial reflectors.…”

A simultaneously "nuclear", permanent, and in-time solution to mankind's energy-related problems would require the relatively rapid manufacture of 10,000-30,000 genuinely sustainable, full-sized (~1 GW e ) reactors. This "nuclear renaissance" would have to be implemented with breeder reactors because today's commercial nuclear fuel cycle is unsustainable and based upon a fuel ( 235 U) that is intrinsically expensive and politically problematic. The purpose of this paper is to point out why a simple/cheap "minimal reprocessing" implementation of the European Union's (EU's) molten salt fast reactor (MSFR) concept represents the most promising way to implement that technical fix:• It would be relatively simple/cheap to both build and operate, • Its fuel cycle is genuinely sustainable (no fuel shortages "forever"), • Radwaste management would also be relatively simple and cheap, • Operation would neither generate nor require huge amounts of transuranic (TRU) elements, • The consequences of accidents (fuel spills, etc.) would be relatively benign, • When steady state is achieved, the world would no longer need its uranium enrichment facilities.

“…Diffusion welds properly made should have microstructures very close to that of the base metal. Nonetheless, specimens were prepared for testing by colleagues under the direction of Prof. Kumar Sridharan at the University of Wisconsin, where substantial corrosion work for molten salt media has been ongoing for some years (Olson, Ambrosek, Sridharan, Anderson, & Allen, 2009). …”

This report addresses present work concerned with heat exchanger development for molten salt service, including the AHTR (Advanced High Temperature Reactor), which uses molten salt for cooling and process heat transfer. These results are an outgrowth of recent work done under the Next Generation Nuclear Plant (NGNP) Project, which was concerned with the diffusion welding of Alloys 800H, 617, and similar materials for oxidation resistance at operating temperatures up to 900 °C. The molten salt systems discussed herein use other alloys such as Alloy N and 242, which show corrosion resistance to molten salt at nominal operating temperatures up to 700 °C. These alloys were diffusion welded, typically at 1150 °C for 3 hours under applied loads of ~5 MPa using the Gleeble thermomechanical testing machine. Thermocalc/DICTRA models were developed to predict diffusion, and compositions of welds with a 15 µm nickel foil interlayer were measured after welding for comparison. Calculated and experimental values were in good agreement. Test specimens were prepared for exposing diffusion welds to molten salt environments. Alloy N and 242 were found to be weldable by diffusion welding, with ultimate tensile strengths about 90% of base metal values. Both diffusion welds and sheet material in Alloy N were corrosion tested in 58 mol% KF/42 mol%ZrF 4 at 650, 700, and 850 °C for 200, 500, and 1000 hours. Corrosion rates were similar between welded and nonwelded materials, typically <10 mils per year.
