چکیده	Determination of plasma density behavior in magnetic confinement system needs to study the plasmamaterials interaction in the facing components such as first wall, limiter and divertor. Recycling of hydro-gen isotope is an effective parameter in plasma density rate and plasma fueling. Recycling coefficientover the long pulse operation, gets to the unity, so it has a significant effect on steady state in magneticfusion devices. Typically, sputtered carbon atoms from the plasma facing components form hydrocar-bons and they redeposit on the wall. In this case little rate of hydrogen loss occurs. In present work azero dimensional particle equilibrium model has been represented to determine particles density rate inmain plasma and wall inventory under recycling effect and codeposition of hydrogen in case of continuesand discontinues fueling methods and effective parameters on the main plasma decay has been studied.
