Abstract

Effect of turbulence on neoclassical tearing modes (NTM) is studied assuming the scale separation between the small scale turbulence and large scale magnetic island. The modified Ohms law taking into account the bootstrap current and the current diffusion due to the small scale turbulence is used. It is shown that the turbulent spreading of the current reduces the pressure gradient drive for NTM and provides an amplitude threshold for NTM excitation.
