Science Problem Fusion reactor blanket
studies. It includes tritium breeding, heat
removal and material studies. Title
Accumulation of hydrogen in multielemental and
multilayered thin films under high-flux,
low-energy H2(H) irradiation modeling and
experiment Goals - to study the behavior of H in
metastable (amorphous, nanocrystalline)
thin films doping effects - to study the role
of very surface (oxide layer, impurities)
on the mechanism of H retention International
