Abstract
Experimental results related to processing of high-temperature gas-cooled reactor fuels containing carbon are discussed. Various reagents, such as nitric acid vapor, oxygen, carbon dioxide and steam have been used to treat this fuel type.
It was also possible to halogenate directly uncoated uranium carbide by means of hydrogen fluoride or chloride. The compounds so formed can be further converted to volatile halides and especially to hexafluorides achieving a high decontamination. Of the processes investigated, the use of the nitric acid vapor opens a new way for both dry and aqueous reprocessing of carbon coated fuels.
