NUCLEAR SAFETY

Main research areas:

  • Probabilistic safety assessment (Level 1, 2 and 3 PSA, risk monitoring)
    • Assimilation, development, performance assessment and documentation of programs and working methodologies used in the probabilistic safety analysis;
    • PSA applications in the design, operation and management of nuclear facilities;
    • Including external events and the consequences of the components ageing in the PSA analyzes for nuclear facilities in operation;
    • Study of nuclear facilities using the analyzers and simulators process;
    • Human reliability analysis and of the interaction man - machine - organization for nuclear facilities in operation, for normal and accident/incident operation situations;
    • Severe accident analyses using the probabilistic methodologies.
  • Deterministic safety analysis for nuclear facilities in exploitation
    • Assimilation, development, performance assessment and documentation of programs and working methodologies used in deterministic safety analysis;
    • Accident scenarios analysis provided in the Final Safety Report of the CANDU NPP (reactor physics, thermal-hydraulic) using the new computational tools and assimilated methodologies;
    • Safety analysis for other nuclear facilities (research reactors, waste treatment facilities, facilities related to transport of nuclear materials, storage etc.) using deterministic methodologies;
    • Severe accident analysis using deterministic methodologies;
  • Support studies regarding the integrity of structures, equipment and nuclear facilities components, including their ageing
    • Experiments simulating the behavior of facilities components in accident conditions;
    • Studies on the consequences of extending the facilities' lifetime on nuclear safety;
    • Hazard studies for nuclear facilities in exploitation;
  • Exploitation the experience of operating nuclear facilities
    • Collecting information regarding the design, operating procedures/normal exploitation of interest facilities and emergency/accident ones, as well as information regarding the human-machine-organization interaction;
    • Estimating based on the international experience in operating and decommissioning similar facilities, of the issues brought-up by decommissioning interest facilities from Romania.
  • Education and training in field of nuclear safety
    • Coordinating in partnership with higher technical education institutions, bachelor/master/PhD papers with topics in the field of nuclear safety, internships in research, engaging students in internal or international projects during work placements;
    • Organizing thematic visits, conferences, round tables on nuclear safety issues, where (anti-) nuclear NGO representatives will be invited, for promoting a positive attitude towards safety culture;
    • Participating in international projects related in areas close to nuclear safety (consequences of the components ageing - APSA).
  • Nuclear facilities safety after the Fukushima-Daiichi events
    • Study of the implications of the Fukushima - Daiichi accident on the content and the quality of the analyzes of nuclear safety.

Main research results:

  • Development computer software packages and qualified methodologies for probabilistic analyses;
  • Carrying out probabilistic security analyzes for the authorization/reauthorization and improving the performance in exploitation and increasing nuclear facilities safety (PSA models and studies for the TRIGA reactor and other nuclear facilities);
  • Development of computer software packages and qualified methodologies for deterministic safety analyzes (development and documentation of our own computer programs: CP2D, DIREN, LEGENTR; assimilation of computer programs purchased by ICN or supplied by external partners within various agreements/international projects: ASTEC, CATHARE, CATHENA, DRAGON, MCNP, RELAP, RFSP, SCALE, WIMS);
  • Carrying out deterministic safety analyzes for the authorization/reauthorization and improving the performance in exploitation and increasing nuclear facilities safety (neutron calculations coupling with thermal -hydraulic; multi-channel modeling of thermo-hydraulic phenomena; modeling and the analysis LOCA accidents for Cernavoda NPP; accidental criticality analysis and biological protection for the transport and intermediate storage of nuclear fuel used);
  • Obtaining experimental results useful in the qualification of computer programs and work methodologies;
  • Human-machine-organization interaction analysis during nuclear facilities exploitation in normal and accident/incident conditions;
  • Estimating the technical, material and human resources needed for decommissioning of the nuclear facilities;
  • Coordinating research internships for students in the final study years, co-tutoring license/masters/doctorates and joint research projects in partnerships with technical higher education institutions (development of training and laboratory modules concerning numerical and experimental methods in reactor physics; coordinating research internships and license papers in partnership with the Polytechnic University of Bucharest and the University of Pitesti);
  • INR accreditation for education / training activities in the field of nuclear safety;
  • Analysis of stress carried out at different nuclear facilities;
  • Including external event in the existing analyzes.
