  A fusion reactor requires plasma pre-heating before the rate of
deuterium-tritium fusion reactions becomes significant. In ITER, radiofrequency
(RF) heating of 3He ions, additionally puffed into the plasma, is one of the
main options considered for increasing bulk ion temperature during the ramp-up
phase of the pulse. In this paper, we propose an alternative scenario for bulk
ion heating with RF waves, which requires no extra 3He puff and profits from
the presence of intrinsic Beryllium impurities in the plasma. The discussed
method to heat Be impurities in D-T plasmas is shown to provide an even larger
fraction of fuel ion heating.
