Understanding the interactions of hydrogen and helium within ferritic steels will aid in the development of materials appropriate for next generation nuclear reactors. We discuss interatomic potentials appropriate for simulating these elements, presenting a potential for the H-He interactions. Preliminary results for small H-He bubbles in bcc iron are given and discussed.
