The management of irradiated graphite (i-graphite) is a worldwide concern. On a global scale, more than 250000 tons of i-graphite has now accumulated. At the same time, progress toward ultimate disposal solutions remains slow, leaving out a vast domain of research work. In Belgium, the main source of i-graphite is the BR1 reactor at SCK•CEN, which is an air-cooled, graphite-moderated reactor with aluminium clad natural uranium as fuel. The moderator consists of 14000 individual blocks of graphite, leading to a total weight of 492 ton. At the current regime, the BR1 operation is destined to continue for a few more decades, but ultimately the reactor will be decommissioned and the graphite blocks removed for treatment and disposal as radioactive waste. When considering irradiated graphite (or i‑graphite) as waste, from a safety assessment point of view, the main concern are the mobile isotopes (in the geo- and biosphere), notably 3H, 14C, and 36Cl, with the latter two isotopes being long-lived. The fate of 14C is currently studied in the EC project CAST (CArbon-14 Source Term), which focuses on the 14C release and speciation from, among other materials, graphite. From recent studies, several potential decontamination methods, aimed at removing 14C from i-graphite, emerged, including thermal oxidation and treatment with molten salts. In particular, thermal oxidation, applied on a laboratory scale to British and German i-graphite, seems a promising technique. The effect of thermal oxidation is based on its removal of a thin layer from the graphite's surface, which is reported, at least for British and German i-graphite, to contain an important fraction of the 14C inventory. The purpose of the current Master thesis proposal is to investigate whether a 14C-enriched surface layer is also present on the BR1 i-graphite. This finding can form the basis for further research on the decontamination of BR1 graphite. The ultimate goal of the study is to find a method to decontaminate the i-graphite in such a way that geological disposal is not needed.
