  In this paper we describe the implementation of the charged current decays of
the kind t --> b l^+ nu_l (gamma) into framework of SANC system. All
calculations are done taking into account one-loop electroweak correction in
the Standard Model. The emphasis of this paper is done on the presentation of
numerical results. Various distributions are produced by means of a Monte Carlo
integrator and event generator. Comparison with the results of CompHEP and
PYTHIA packages are presented for the Born and hard photon contributions. The
validity of the cascade approximation at one-loop level is also studied.
