This report contains the breakup bubble model developed at the UPM Chair of Nuclear Technology. The model is based on experimental studies of gas-liquids hydrodynamics performed by Battelle Columbus. The expressions developed, by this institution, for the arithmetic average bubble surface and volume have been used for the development of the model. The bubble breakup model has been implemented in the BUSCA JUN '90 code and validated against the ACE Phase A tests. A sensibility analysis has also been performed for the AA1, MnO test. Some conclusions have been obtained. The input data for the four ACE Phase A tests have been included in the Annex.
