Transmutation by irradiation in nuclear reactors of long-lived nuclides like 241 Am is
therefore an option for the reduction of radiotoxicity and heat production of waste packages
to be stored in a repository. The MARINE irradiation experiment is the latest of a series of
European experiments on americium transmutation (eg EFTTRA-T4, EFTTRA-T4bis,
HELIOS, MARIOS, SPHERE) performed in the High Flux Reactor (HFR). The MARINE …
