The dual parton model provides a unique picture not only for hadron-hadron interactions, but also for the description of particle production in hadron-nucleus and nucleus-nucleus collisions at high energies. Within this model the high-energy projectile undergoes a multiple scattering process as formulated in Glauber`s approach; particle production is realized by the fragmentation of colorless parton-parton chains constructed from the quark content of the interacting hadrons/nucleons. DTUNUC, the author`s Monte Carlo realization of the model includes the cascading of secondaries within the target as well as in the projectile which is suppressed by the formation time concept. Semihard parton-parton collisions (for the description of minijet production) are not included in this version. With this restriction the model should not be applied beyond RHIC energies ({radical}s {approx_equal} 200 GeV, E{sub lab} {approx_equal} 20 TeV). At lab energies below 5 GeV the formation zone cascade becomes the conventional intranuclear cascade; thus the model may be applied in the range well below 1 GeV. DTUNUC should eventually replace the present hadronic event generators in the FLUKA-hadron cascade code.
