Production in Nuclear Reactors
Significant quantities of the three light platinum group metals—ruthenium, rhodium and palladium—are formed as fission products in nuclear reactors. With escalating prices and increasing global demand, reactor-produced noble metals are emerging as an alternative source. Various reports are available on the possibility of recovering fission noble metals from spent nuclear fuel.
Recently there is an upsurge in the recovery of valuable fission products which reflects in the form of articles in leading scientific journals. Palladium has been of special interest due to its less complex behavior when compared to rhodium and ruthenium. The special interest in palladium may be also due to its widespread application in chemical catalysis and the electronics industry. Several research groups are exploring the possibility of recovering palladium by various methods like direct electrolysis of high-level liquid waste, using room temperature ionic liquids (RTILs) as electrolyte for nuclear fuel dissolution and recovery, solvent extraction, ion exchange, etc. Room temperature ionic liquids have been employed to recover rhodium, and ruthenium also recently.

Famous quotes containing the words production and/or nuclear:
“The growing of food and the growing of children are both vital to the family’s survival.... Who would dare make the judgment that holding your youngest baby on your lap is less important than weeding a few more yards in the maize field? Yet this is the judgment our society makes constantly. Production of autos, canned soup, advertising copy is important. Housework—cleaning, feeding, and caring—is unimportant.”
—Debbie Taylor (20th century)
“The problems of the world, AIDS, cancer, nuclear war, pollution, are, finally, no more solvable than the problem of a tree which has borne fruit: the apples are overripe and they are falling—what can be done?... Nothing can be done, and nothing needs to be done. Something is being done—the organism is preparing to rest.”
—David Mamet (b. 1947)
