This paper summarizes the work being performed at the Department of Nuclear Engineering (www.din.upm.es) of the Universidad Politécnica de Madrid to improve the education and training of future Spanish nuclear engineers according to the Bologna rules. We present two main efforts introduced in our programme: i) the understanding of the current computational methodologies/codes starting from the nuclear data processing, then the lattice and core calculations codes, and finally the power plant simulators, ii) the development of practical teaching-learning experiences with an Interactive Graphical Simulator of a real nuclear power plant
