The behaviour of the pomeron propagator in the external nuclear field is
studied in the (2+1)-dimensional QCD. It is shown that in the physically
interesting case when the field does not vanish at large rapidities the
propagator in the field vanishes much faster than in the vacuum, in agreement
with the results found in the local Regge-Gribov model. However if the nuclear
field vanishes at high rapidities the field does not change the behaviour of
the pomeron propagator.Comment: 14 pages, 10 figure
