Abstract. Operational window for the ITER steady state scenarios with
fusion gain Q exceeding 5 is analyzed. The ideal MHD mode stability analysis
is carried out for different shapes of plasma current profile taking into
account the ITER design wall position. Possible range of plasma parameters
with stable operation is found with moderate normalized beta (about 2.6) and
moderate enhancement factor HH (about 1.3).
