Loss-of-primary-flow-without-scram tests: Pretest predictions and preliminary results

A US perspective on fast reactor fuel fabrication technology and experience part I: metal fuels and assembly design

“…Metal fuel has often been selected for use in fast reactors because it can be easily fabricated and has high thermal conductivity, high fissile and fertile density capability, and small Doppler reactivity feedback [38]. Furthermore, metallic fuels are easily recycled using melt refining or can be readily dissolved and electrorefined in a molten salt electrolyte.…”

Phase characteristics of a number of U–Pu–Am–Np–Zr metallic alloys for use as fast reactor fuels

“…Fuels for fast reactors must behave in a benign manner during core transient events, maintain integrity at high burnup, lend themselves to low-loss recycling processes, and be easily fabricated with minimal material loss in a remote handling environment. The application of metal alloy fuels for use in fast reactors for MA transmutation is of particular interest, due to the ease in fabrication, high thermal conductivity, high fissile and fertile density capability, and small Doppler reactivity feedback [1]. Because of this, metal alloy fuels are one of the common fuel types considered for fast reactor recycle.…”

Metallic fast reactor fuel fabrication for the global nuclear energy partnership

“…One of the two leading candidates for next generation fast reactor fuels is metal alloys, resulting from the notable successes obtained from driver fuel utilization and/or testing in the 1960s to early 1990s in both the experimental breeding reactor-II (EBR-II) and the fast flux test facility (FFTF). Metal fuel has the advantage of simple fabrication, high thermal conductivity, high fissile and fertile density capability, and small Doppler reactivity feedback [5]. Furthermore, metallic fuel can be simply recycled using either melt refining or an electrorefining process.…”
