Surveying of the inner first wall (IFW) during the last two years of operation (P. max = 9 MW, t = 20 s) has shown an important disparity of the power deposition on this belt limiter and the appearance of localised hot spots. These anomalies were imputed to the misalignment of the limiter sectors and to the propagation of braze defects. During the autumn 1991 shut-down, four IFW sectors were rebrazed and the inner first wall was realigned within less than one mm with respect to the toroidal field coils. Recent results have shown that these corrections were valuable for the long pulse operation (1 minute duration).
