Startup "Marathon Fusion" Announces Transmutation of Mercury into Gold Using Thermonuclear Fusion Neutrons

Recently, San Francisco-based startup Marathon Fusion announced that it has successfully used high-energy neutrons produced by deuterium-tritium (D-T) thermonuclear fusion reactions to transmute the element mercury into gold, claiming that its yield reached ten times the previously recorded level at CERN. It is reported that the technology is based on high-energy neutrons released by D-T fusion reactions striking mercury-198 nuclei, stripping one neutron to convert them into the radioactive isotope mercury-197, which subsequently decays to ultimately form gold-197, the only stable isotope of gold. Marathon Fusion published gamma-ray spectroscopy as characteristic evidence for the presence of mercury-197; however, the specific mass of gold produced remains at...

Russia proposes optical laser monitoring method for spent nuclear fuel reprocessing

Recently, a research team from Sechenov University in Russia, together with the Proryv Project and the All-Russian Scientific Research Institute of Inorganic Materials (VNIINM), published latest results in the journal Applied Spectroscopy, proposing a non-contact optical method for continuous monitoring of the spent nuclear fuel reprocessing process. It is reported that in the liquid-liquid extraction process of spent nuclear fuel reprocessing, traditional laboratory analysis has problems such as long sampling time and increased risk of radioactive waste. The research team introduced Raman Spectroscopy to monitor the state of extractants such as tributyl phosphate in the organic phase, measuring a median error of about 1%; meanwhile, laser-induced breakdown spectroscopy (LIBS) was used to determine the concentration of metal elements in the aqueous phase, with an average error controlled at 4%–8%, achieving near-real-time synchronous monitoring of the two-phase streams.
