TEM samples of alloy T91 were irradiated in-situ in a TEM with 1 MeV Kr ions so that irradiation induced defects could be followed in situ and characterized as a function of dose at different temperatures (25C, 400C, and 470C). Dynamic observations of irradiation induced defect formation and evolution were done at the different temperatures. The loop size and density was measured as a function of dose. It was observed that (i) the density of irradiation induced loops increases at low doses (build up) and then decreases at higher doses, (ii) both <111> and <100> loops were observed; (iii) at higher doses, the decrease of number of loops affects more the <111> loop population. The possible loss mechanisms of the <111> loops are discussed.
