Reference operating scenarios for the physics phase of the International Thermonuclear Experimental Reactor (ITER) rely on low temperature, high density operation for good divertor performance. Operating points in this region are usually thermally unstable and active burn control is required to maintain operation at the selected operating point. We present a series of transport simulations of ITER burn control scenarios with modulated neutral beam heating, using the 1-1/2D code WHIST. Our results indicate that control is possible, except at very high densities ({l angle}n{sub e}{r angle} {ge} 1.80{times}10{sup 20} m{sup {minus}3}) where off-axis heating due to the poor beam penetration makes control difficult, especially for negative perturbations 15 refs., 20 figs.
