Working Group on Analysis and Management of Accidents (WGAMA)
Programme of work
The GAMA programme of work includes the
following areas, covering all the items in its mandate and the CSNI
high-level and safety issues/topics List. The main objectives of the
work are to improve the knowledge base available to member countries in
the area of accident analysis and management and to reach international
technical consensus in the field. The current four main areas of work are:
1. Thermal-Hydraulics of the Reactor
Coolant System and Related Safety and Auxiliary Systems
- Qualification and application of best estimate methods, including uncertainty methods and evaluation (BEMUSE) programme;
- Use of Computational Fluid Dynamics (CFD) codes for NRS;
- Transfer of competence, knowledge and experience gained through CSNI activities in the field of thermal-hydraulics (THICKET-2008);
- PKL-2 Joint Project on boron dilution and fuel uncovering;
- ROSA Joint Project to resolve issues in thermal-hydraulics analyses relevant to light water reactor (LWR) safety;
- PSB-VVER Joint Project to provide the experimental data
needed to allow full validation of the computer codes used in the thermal-hydraulic
analysis of VVER-1000 reactors.
2. In-Vessel Behaviour of Degraded
Cores and In-Vessel Protection
-
Accident progression benchmarking exercise (predictability of TMI-2 core degradation);
-
ISP-46 exercise based on the PHEBUS FPT-1 test;
- Steam explosion resolution for nuclear applications (SERENA) phase-1 analytical exercise (FCI and steam explosion);
- MASCA Joint Project on in-vessel corium behaviour.
3. Containment Behaviour and
Containment Protection
4. Fission Product Release, Transport,
Deposition and Retention
5. Co-ordinated Programme,
Cross-cutting issues, and others
- GAMA integrated plan;
- Fire safety (Fire and PRISME joint projects;
- GAMA/WGOE workshop and action plan for updating the
knowledge base for ECCS recirculation reliability with respect to
the potential for strainer clogging;
- GAMA/WGRISK/IAGE workshop on evaluation of uncertainties,
with particular emphasis on severe accidents;
- SARNET seminar on severe accident knowledge transfer.
