Abstract
The so-called \"Cristallini Method\" for sampling of UF6 by adsorption and hydrolysis in alumina pellets inside a fluorothene P-10 tube was developed by the Brazilian- Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) several years ago. This method has several advantages compared to the currently used sampling method, for which UF6 is distilled into a stainless steel tube for transportation, with hydrolysis and isotopic analysis being performed after shipping to the analytical laboratory. Using the Cristallini sampling method the transport will be cheaper and safer concerning radiological and chemical protection aspects.
