"The #US has more than 100,000 tons of waste accumulated from #nuclearpower plants. Instead of waiting about 3,000 years for it to become nontoxic, a new process could reduce that time to around 300 years and reclaim 90 percent of the #wasteasnewfuel...The technique is called #pyroprocessing. It uses molten salts and electricity to pull out most of the #radioactivematerial and leaves little toxic waste behind...#BLSK plans to begin commercial #reprocessing of #nuclearwaste in a facility to open in eight to 10 years."

LIST OF INDUSTRIAL PROCESS

                      Industrial processes are procedures involving chemical, physical, electrical or mechanical steps to aid in the manufacturing of an item or items, usually carried out on a very large-scale. Industrial processes are the key components of heavy industry. 1. General processes   These may be applied on their own, or as part of a larger process. Liquefaction of gases – for ease of…

The Korea Atomic Energy Research Institute (KAERI) has been developing pyroprocessing technology for recycling useful resources from spent fuel since 1997. The process includes pretreatment, electroreduction, electrorefining, electrowinning, and a waste salt treatment system. This paper briefly addresses unit processes and related innovative technologies. As for the electroreduction step, a stainless steel mesh basket was applied for adaption of granules of uranium oxide. This basket was designed for ready handling and transfer of feed material. A graphite cathode was used for the continuous collection of uranium dendrite in the electrorefining system. This enhances the throughput of the electrorefiner. A particular mesh type stirrer was designed to inhibit uranium spill-over at the liquid Cd crucible. A residual actinide recovery system was also tested to recover TRU tracer. In order to reduce the waste volume, a crystallization method is employed for Cs and Sr removal.Experiments on the unit processes were tested successfully, and based on the results, engineering-scale equipment has been designed for the PRIDE (PyRoprocess Integrated inactive DEmonstration facility).
