Main experience in the nuclear sector

The national and international projects in which the Group has been involved in recent decades have concerned various aspects related to the nuclear energy sector.

• Decommissioning and Waste Management: 
  • decommissioning strategies and management and characterization of waste and nuclear materials;
  • design and qualification of containers for the transport and temporary and permanent storage of radioactive waste;
  • participation in the UNI technical bodies and in the Scientific Council of SOGIN;
  • anti-terrorism detection and "nuclear security" systems.

• Reactor Physics: 
  • development of deterministic numerical and deterministic-stochastic hybrid models for neutron transport;
  • design of advanced reactor cores and reactor configurations for Boron Neutron Capture Therapy (BNCT);
  • support for particle physics experiments;
  • use of the most common Monte Carlo codes for radiation transport (MCNP, OpenMC, Serpent);
  • use of the deterministic PartiSN code.

• Severe accidents in nuclear installations:
  • modelling analysis of severe accidents and prediction of relevant transients in installations (MELCOR, ASTEC and ECART codes);
  • modelling activities on the behaviour of dusts in fusion reactors, in collaboration with ENEA Frascati and RSE – Milan.

• Structural Mechanics and Nuclear Constructions:
  • mechanical design and design and safety analysis in relation to internal and external events at reactors with ANSYS, MARC, PATRAN, COMSOL, DYTRAN codes;
  • analysis of the problems of degradation and aging of nuclear components (in support of the extension of operation, LTO);
  • development of innovative HPC and AI methodologies for monitoring and predictive maintenance of nuclear fission and fusion plants.

• Networking for higher education:

  • training of TSO staff in cooperation with ENSTTI.

• Fusion Reactors:
  • thermo-hydraulic and safety studies of blanket refrigeration systems (WCLL) for ITER and DEMO (with codes RELAP5, SIMMER, MELCOR, ECART);
  • analytical and experimental studies of the behaviour of fusion reactors in the event of an accident (small and large scale equipment).

• Nuclear instrumentation and measurements and radiation protection:
  • radiation protection management activities at the level of Radiation Protection Expert;
  • measurements of environmental radioactivity;
  • shielding design;
  • experimental testing of radioactive gas filter systems (for EdF);
  • design of dosimetry and sensor equipment.

• Nuclear thermohydraulics:
  • aspects of thermohydraulics of advanced reactors (AP600, SBWR, AP1000, EPR, VVER, LFR, SCWR, VVER);
  • use of calculation codes for the thermohydraulics of light water nuclear reactor systems and innovative (RELAP5, CATHARE) and CFD codes (FLUENT, CFX, STAR-CCM+);
  • experimental activities on passive systems (heat and mass transfer, natural and gas-injection assisted circulation (with own experimental equipment and in collaboration with SIET and the ENEA Brasimone center);
