DIMNP is a research structure of the University of Pisa, with more than 50 academic and research staff members and about 30 technical-administrative staff members. Since its institution, the Department has been characterized by a strong orientation of the activities towards collaborations with Italian and European Industries in applicative research projects with wide scientific and technological significance. The main research activities regard safety analysis in nuclear and conventional fields, activities related to peaceful applications of nuclear energy, with main emphasis on plant design and safety, radiation measurements and reactor physics, management of risk and emergency in industrial plants, characterization and machining of conventional and innovative materials, design of machines and two- and four-wheel vehicles, and related studies on strength, reliability, lubrication, robotics and automation in industrial processes, and rapid prototyping technologies. Beyond these topics, several applicative studies have been carried out in many different fields. Among the most important collaborations, the following companies can be mentioned: the Italian University Ministry (MIUR), the European Union, ANPA, ENEA, ENEL, FIAT, FIAT-AVIO, PIAGGIO, NUOVO PIGNONE, BREDA, ANSALDO, AGIP, etc.

Nicola Forgione is presently Assistant Professor of Nuclear Power Plants at the University of Pisa. He has a Ph.D. in nuclear engineering (Safety of Nuclear Plants) in 2000. Dr. Forgione performed research activities in the field of Nuclear Reactor Safety since his degree in Nuclear Engineering in 1996. In the following, a summary of the main achievements is reported.

  • Experiments and modelling of falling film evaporation.
  • Modelling of condensation in the presence of noncondensable gases.
  • Measurement and statistical characterisation of falling films.
  • CFD applications to heat and mass transfer of interest for Light Water Reactors, Liquid Metal Reactors and Fusion Reactors.
  • Numerical analysis of heat conduction.
  • Experiments and code predictions on natural and gas-injection enhanced circulation.
  • Experiments on steam condensation in the presence of noncondensable gases
  • Actively involved in different EC Project as INCON, DABASCO, SCACEX, EUROTRANS, ELSY and THINS.

He is teacher of the course “Elements of Applied Informatics” at the 3rd year of the “Laurea in Sicurezza Industriale e Nucleare” of the University of Pisa;
He supports the courses of “Thermodynamics and Thermal-hydraulics”, “Nuclear Power Plants” and “Thermo-technical Plants” in the Degree in Nuclear and Mechanical Engineering.

Walter Ambrosini is presently Associate Professor Assistant Professor of Nuclear Power Plants at the University of Pisa. He obtained a PhD in nuclear engineering (Safety of Nuclear Plants) in 1988. Prof. Ambrosini performed research activities in the field of Nuclear Reactor Safety since his degree in Nuclear Engineering in 1985. In the following, a summary of the main achievements is reported.

  • Application and validation of codes for safety analysis of nuclear reactors
  • Development of models for basic thermal-hydraulic phenomena and plant transients: development and application of numerical methods for heat transfer and fluid-dynamic problems; proposal and application of mechanistic correlations for basic phenomena; development of codes for the analysis of plant transients; models for instabilities in single-phase loops and boiling channels
  • Experimental activities: experimental studies on falling film evaporation (DABASCO Project, 4th Framework Programme);
  • statistical characterisation of falling films; experiments on natural circulation and gas-injection enhanced circulation for ADS applications in a water loop; experiments on steam condensation in the presence of non-condensable gases

He started supporting the courses of Thermal-Hydraulics and Numerical Methods for Nuclear Reactors for the Degree in Nuclear Engineering. Walter Ambrosini is President of the Teaching Board of the Research Doctorate in Nuclear and Industrial Safety (SNI) at the University of Pisa. Though not responsible, he has been de facto involved in contracts with the European Commission (DABASCO, INCON; SCACEX; THINS).
