Zero-dimensional global particle balance modeling was applied to the JET-ILW tokamak to investigate the particle balance in the main plasma and wall inventory, including the wall recycling effect, co-deposition, and sputtered particles. In this model, we used the fueling rate, based on the experimental work and vacuum pumping of the JET-ILW. Our modeling results were then compared with experimental data from the JET-ILW tokamak. A qualitative agreement was observed between the model results and the experimental data. In addition, this model could be a promising for studing the particle behavior in ITER-like reactors.
