Abstract
It has been understood that thermonuclear plasma confinement and behaviour of the plasma was
mostly depend upon the magnetic surfaces on which the confining magnetic field and the
plasma current he. However magnetic surfaces are not stable and prone to the
magnetohydrodynamic(MHD) stabilities and reconnection and finaly they lead to the magnetic
island formation. Resistive magnetohydrodynamics and instabilities are reviewed both
experimentally and theoretically, among them; tearing mode and mode locking phenomena,
topological relaxation (sawteeth oscillation), magnetic island overlap and plasma minor and
major distruption.are investigated. The tearing mode growth rate are determined. Magnetic field
reconncection on the rational surfaces and magnetic island formation, magnetic island growth
rate and plasma confinement relation and energy confinemenet degradation are emphasized:
The island width and island evaluation equations are derived. Performance limitation and MHD
activities and mode structure m=0,n=0,m=1,n=1 and their sidebands and overlap are reviwed.
Plasma distruptive phenomena with up to date experiments are presented.
