THE SECOND SAUDI INTERNATIONAL CONFERENCE ON NUCLEAR POWER ENGINEERING (SCOPE-2)

The safe decontamination of abandoned radioisotope and radiopharmaceutical production facilities in Indonesia for reuse is a pressing need due to the increasing local demand and the country's current dependence on imports. This study presents a structured risk evaluation model for the decontamination process in such facilities, integrating qualitative risk assessment with the Analytic...

The revitalization of abandoned nuclear facilities requires a strategic approach that emphasizes safety, operational efficiency, and sustainability. Robotics technology has emerged as a transformative solution, offering remote operation capabilities that reduce human exposure to hazardous environments while increasing precision and effectiveness in revitalization tasks. International examples...

The increasing number of disused sealed radioactive sources (DSRS), particularly from cobalt-60 (⁶⁰Co) teletherapy units, poses a significant challenge for radioactive waste management in Indonesia. In accordance with national regulations, these sources must be securely transported and stored by the authorised institution. However, the lack of cost-effective and certified transport containers...

A robust and accessible database of radioecological parameters is essential for effective emergency preparedness and response to radiological and nuclear incidents. Such a database compiles critical information on radionuclide behavior in various environmental compartments, including soil-to-plant transfer factors, distribution coefficients, ecological half-lives, and bioaccumulation rates...

This paper presents an innovative methodology for analyzing and modeling fission product releases in Small Modular Reactors (SMRs) using the Probabilistic Model Chain Methodology (PMCM). The proposed approach integrates detailed site-specific meteorological data, reactor design parameters, and severe accident scenarios to enable more accurate predictions of radioactive plume dispersion and...

The rapid detection and characterization of accidental radioactive releases is critical for public safety, environmental protection, and informed emergency response. In the Gulf region, the increasing presence of nuclear power infrastructure—including the operational Barakah Nuclear Power Plant (UAE), the Bushehr facility (Iran), and a planned plant in Saudi Arabia—necessitates robust regional...

The dispersion of hazardous pollutants in urban environments presents a complex challenge, especially in the context of nuclear accidents or malicious releases involving radioactive substances. In such scenarios, understanding the transport mechanisms of contaminants is crucial for emergency preparedness, risk assessment, and public safety. Numerical simulations based on computational fluid...

This study focuses on enhancing safety validation methods for small modular reactors (SMRs) by investigating the behavior of passive containment cooling systems (PCCS) during severe accidents. Many SMR designs rely on a containment-water pool coupling, which acts as a final heat sink during events like loss-of-coolant accidents (LOCA). The thermal-hydraulic behavior inside the containment—such...

The revitalization of the Radioisotope and Radiopharmaceutical Technology Facility (ITRR) is a critical step toward strengthening the domestic production of radioisotopes in Indonesia. Previously operated by the Indonesian Nuclear Industry (INUKI), the facility has been transferred to the National Research and Innovation Agency (BRIN) for rehabilitation following years of inactivity and...

Nuclear safety analysis, particularly in the context of severe accidents (SAs), requires modeling complex physical and stochastic phenomena. The Risk-Oriented Accident Analysis Methodology (ROAAM+) framework, under development at KTH, addresses this by integrating full-scale mechanistic models with computationally efficient surrogate models (SMs). However, many existing SMs lack the capacity...

The world currently employs nuclear energy to meet the growing energy demand and contributes 10% of global electricity output. Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs) are the main types of reactors used in the nuclear power industry. Together, they are known as Light Water Reactors (LWRs) and account for over 90% of the world’s reactors, with PWRs making up more...

A 2 page-extended abstract, titled "Seismic Response Calibration of a Scaled CPR1000 Prestressed Concrete Containment Vessel Using ABAQUS" has been attached to the submission.

Filtered Containment Venting System is a passive safety system that is used for mitigation of severe accidents. Its main objectives are control of over-pressurization and removal of radioactive products like iodine. An FCVS tank with scrubbers is connected with containment via a pipe. When pressure inside the containment starts building up after an accident, this system gets activated. The air...

Phase Change Materials (PCMs) have garnered considerable attention for thermal energy storage applications due to their capacity to absorb and release latent heat during phase transitions. In nuclear power plant passive containment cooling systems, the effectiveness of PCMs heavily depends on the thermal medium used to initiate and sustain melting. This study presents a comparative numerical...
