The creep behavior of actively cooled alloys exposed to neutron irradiation in fusion reactors is expected to critically affect the operation of reactor components. Here, experiments and simulations of a 16 μm thick tungsten wire exposed to low-temperature irradiation reveal stress relaxation rates far exceeding those associated with thermal creep.
