Determination of14C in spent HTGR fuel elements

Spent HTGR-fuel spheres were analysed chemically to determine their14C content.14C is mainly (∼96%) produced in the graphite matrix of the fuel. About 75% of the14C is derived from14N. More than 99% of14C is released as CO2 during the combustion of the fuel elements. Assuming no14C retention, the maximum body burden at the critical region of a 50000 MW HTGR reprocessing plant will be ∼ 70 mrem/a.
