Safety Analysis of SMR with PAssive Mitigation strategies – Severe Accident
Short description
The key objective of SASPAM-SA is to investigate the applicability and transfer of the operating large-LWR reactor knowledge and know-how to the near-term deployment of integral PWR (iPWR), in the view of Severe Accident (SA) and Emergency Planning Zone (EPZ) European licensing analyses needs. This includes also dedicated actions on Accident Tolerant Fuels (ATF) as well as on In-Vessel Melt Retention (IVMR). The proposed project outcomes should be supportive for the iPWR licensing process by bringing up key elements of the safety demonstration needed. This will speed up the licensing and siting process of iPWRs in Europe. To do that, four main elements, not addressed in other on-going SMR oriented initiatives, will be investigated:
- Identification of plausible SA scenarios for iPWR designs;
- Identification of the conditions in the vessel and in the containment that characterize iPWR designs, in hypothetical postulated SA scenarios, and differ significantly from those in large-LWRs;
- Study the applicability of the existing experimental database to iPWR and identify new experimental needs;
- Assess the capability of internationally recognized European and Non-European computational tools (largely used in Europe) to describe the behaviour of the most promising iPWR designs during postulated SA scenarios and to predict the resulting radiological impact on- and off-site.
