Dr. Yacine Addad holds the Associate Department Chair in Nuclear Engineering and Deputy Director of the Emirates Nuclear Technology Center (ENTC) within Khalifa University, UAE. He is an expert in the field of nuclear Thermal-Hydraulics (T-H) analysis. He is leading the Emirates Nuclear Technology Center (ENTC) Theme-1 research team focusing on the assessment of the thermal hydraulic safety analysis codes capabilities to mimic dominant T-H phenomena occurring in nuclear power plants under postulated accident scenarios including rare events.

Dr. Addad is actively involved in many UAE and internationally coordinated research programs. He is a leading academic researcher and has attracted over $8 Million in grants as PI and Co-I from various bodies including, FANR, ENEC, UK funding councils, and ASPIRE programs to support R&D in nuclear. He has given invited lectures and short courses in United Kingdom, Algeria, Japan, South Korea, France, and the United Arab Emirates. Dr. Addad is the author and co-author of 100+ articles in refereed journals and peer-reviewed conference proceedings.

Research Projects

1- Morad Project: The primary objective of this project is to augment the United Arab Emirates' capacity to simulate the dispersion of radionuclides across marine, atmospheric, and continental environments, while meticulously considering regional and local characteristics. In light of the UAE's commencement of its nuclear program, marked by the construction of four nuclear power plants, the nation is earnestly dedicated to bolstering its human resource capabilities in the realm of nuclear safety. The present undertaking not only aligns with the overarching aspiration of diversifying the Emirate's economy but also serves to mitigate the impact of this newly embraced sustainable energy source on the natural environment.

2- OECD-ATLAS-III Project: Following the successful participation of the KU team in Phase II of the OECD-ATLAS project, where they achieved significant safety analysis milestones through Validation and Verification (V&V) of the system code, FANR and Khalifa University continue their collaboration. They are now focused on implementing Phase 3 activities within the ATLAS project to produce numerical results for pre-test and post-test simulations. Additionally, this project aims to expand its scope by comparing two principal system codes, RELAP5 and TRACE, and by developing experimental capabilities at Khalifa University through the commissioning and operation of separate effect test facilities.

3-ASPIRE Project: Molten Corium-Concrete Interaction (MCCI) is considered a significant concern due to its propensity to cause concrete ablation through the dissipation of heat from molten corium onto the concrete walls. Models for MCCI currently employed within numerical tools still harbor notable uncertainties, necessitating enhancements to reinforce the reliability of numerical predictions related to MCCI. In light of this, the present project intends to develop a numerical model grounded in a multi-physics computational fluid dynamics (CFD) framework. This model will be utilized to investigate the thermal behavior of molten corium and its consequential impact on concrete ablation during MCCI under severe accident conditions.
