The overall objective of PASTELS is to improve the ability of European nuclear actors to design and deliver innovative passive safety systems and simulate their behaviour to support the safety demonstration.
PASTELS aims at making significant progress in the study of two specific passive systems, the Containment Wall Condenser (CWC) and the Safety Condenser (SACO) by:
- Building on and leveraging existing available computational codes to simulate the relevant thermal-hydraulics phenomena,
- Developing a robust, validated, multi-scale simulation methodology of passive systems,
- Performing new experimental studies to obtain the relevant validation data.
