Pyroprocessing (from Greek Πυρος = fire) is a process in which materials are subjected to high temperatures (typically over 800 °C) in order to bring about a chemical or physical change. …

Pyroprocessing R & D activities span the range from fundamental property measurements to pilot-scale processing demonstrations to develop, and engineer innovative and commercially viable …

2012年6月22日 · Pyroprocessing begins by chopping the ceramic fuel into little pieces and converting it into metal. Then it’s submerged in a vat of molten salts, and an electric current …

2015年12月1日 · Pyroprocessing is a high-temperature electrochemical fuel processing technology for recycling the spent fuel into metal fuel for a nuclear fast reactor. In other words, …

In pyroprocessing, chemical separations largely take place in high-temperature molten salts. The oxide reduction (OR) cell is used to chemically convert oxide fuels to metals.

Our pioneering pyrochemical processes recycle used nuclear fuel into new fuel and durable waste forms. Advanced molten salt technologies support advanced reactor designs and safety …

Pyroprocessing Technology (aka Electrochemical or Electrometallurgical Processing) • Developed at Argonne National Laboratory under the Integral Fast Reactor program in 1980s to provide − …

Therefore, the development of advanced partitioning processes, based either on hydrometallurgical or on pyrometallurgical technologies, has received an increasing interest in …

Forms for the EBR-II Spent Fuel Treatment Process,” International Pyroprocessing Research Conference, Idaho National Laboratory, INL/CON-10-19439, November 2010.

Pyroprocessing uses electrochemical reactions to extract fissile material from used fuels and generate source material suitable for recycle. The processes were originally developed to treat …
