review text: A multicode consisting essentially of three modules, the ''first wall module'', the ''neutral gas module'' and the ''plasma module'', is applied to compute the time evolution of the protium, deuterium and tritium densities within the wall of a fusion reactor. The first wall module describes the protium, deuterium and tritium diffusion implantation and trapping within and the recombination processes at the wall. The neutral gas module resorting to Monte-Carlo techniques computes the atomic and molecular flux densities hitting the wall. The plasma module calculates the parameters of the plasma background on the basis of the familiar transport equations. In the first wall module the predictor-corrector method is employed for solving the coupled system of diffusion equations with nonlinear boundary conditions. Nonanalogue methods, a combination of the tracklength and the collision estimator are applied in the neutral gas module to reduce the variance. As a specific example the code is applied to the first wall of an INTOR-like device.
