Abstract
After an analysis of published experimental results and theoretical models on irradiation creep, the authors of a recent paper [1] conclude that “the strain accumulated in the material of the first wall of fusion reactors due to creep under pulsed irradiation… can reach a inadmissible high level”. This conclusion was reached since recent experimental results [2, 3] have been omitted from the analysis and incorrect input parameters for the theoretical models have been assumed.
