A computer code to simulate impurity transport in tokamaks are described. The code solves the coupled rate and diffusion equations for a set of plasma ions, hydrogen isotopes plus several charge states of one or more impurity elements. Neoclassical transport for all ion species including both density gradient and temperature gradient effects is used. Impurity ions and plasma ions can be either in Pfirsch-Schluter or plateau-banana regime. Anomalous transport is also considered. Several models are used for atomic rates. The source of impurity is calculated from the sputtering of limiter and wall. The rate and diffusion equations are solved by Cranck-Nicholson's implicit scheme. The Crank-Nicholson's method is compared with more accurate Gear's method and a fairly good agreement is found between the two methods.
