  Recent progresses in the description of the latter stage of nuclear fission
are reported. Dynamical effects during the descent of the potential towards
scission and in the formation of the fission fragments are studied with the
time-dependent Hartree-Fock approach with dynamical pairing correlations at the
BCS level. In particular, this approach is used to compute the final kinetic
energy of the fission fragments. Comparison with experimental data on the
fission of 258Fm are made.
