    Nuclear power plant cogeneration with Multi-Effect Distillation (MED) offers a solution to provide both electricity and a freshwater supply in West Kalimantan. The influence of tropical seawater quality on the corrosion and scale formation potential and its implications for desalination performance were described. A physicochemical characterization of seawater quality for consistent feedwater is crucial to ensure desalination performance. Results indicated moderate corrosion rates (0.46–0.47 mm/year), driven largely by high chloride concentration, elevated TDS, and near-neutral pH. The content of Fe, Zn and Pb is potentially accelerating corrosion. In contrast, consistently negative LSI values (−1.83 to −2.44) confirmed negligible scaling potential but high corrosivity. Corrosion will accelerate material degradation, reduce thermal efficiency, and decrease the ratio between the amount of distillate produced and steam used. This also impacts the reliability and safety of nuclear installations, which require a freshwater supply for cooling systems. These findings emphasize corrosion as the critical operational challenge and highlight the need for corrosion-resistant materials, protective coatings, cathodic protection, and advanced pretreatment to ensure safe and sustainable MED–nuclear cogeneration systems in coastal environments. • Site-specific seawater analysis for nuclear cogeneration desalination (Pantai Gosong). • High chloride, TDS, and heavy metals accelerate corrosion in MED feedwater. • LSI results show negligible scaling potential but significant corrosivity risk. • Corrosion is identified as the critical challenge for safe and efficient MED operation. • Mitigation strategies include corrosion-resistant alloys, coatings, and pretreatment.
  • Integrated seismic modelling for NPP risk assessment in Serpong: Using hybrid machine learning clustering and support vector machine methods

    Open Geosciences, 2026
    The pursuit of clean and sustainable energy in Indonesia has intensified focus on nuclear power, positioning Serpong, West Java, as a prospective site. While previous studies have addressed regional seismicity, a comprehensive, high-resolution seismic hazard assessment – critical for the safety of nuclear power plants (NPPs) – remains underdeveloped. This study bridges the gap by implementing a hybrid machine learning framework that integrates DBSCAN, Hierarchical Clustering, and Support Vector Machine (SVM) to delineate seismic source zones and evaluate fault activity. Our methodology leverages an updated earthquake catalog up to 2024 and incorporates newly identified seismic sources to enhance clustering precision. The analysis delineates 12 distinct seismic zones with heterogeneous magnitude and depth distributions, pinpointing specific high-risk areas. Gutenberg-Richter analysis reveals anomalously low b-values within these zones, signaling a heightened potential for large-magnitude seismic events. Furthermore, the SVM model successfully captures complex, non-linear seismic patterns, significantly improving hazard prediction accuracy. The findings provide critical, data-driven insights for informed site selection, resilient structural design, and proactive risk mitigation strategies. The proposed framework establishes a robust and transferable paradigm for preliminary seismic hazard evaluation of critical infrastructure in seismically active regions globally.

    Case Studies in Chemical and Environmental Engineering, 2024
    The Small Modular Reactor emerges as a recommended technology for nuclear power plant (NPP) development in West Kalimantan, particularly at the Pantai Gosong site. NPP demand highly purified water for cooling system, while seawater contains high TDS, so desalination by utilizing heat and power from NPP, offers a viable solution. Additionally, desalination products can supply freshwater to communities within a 10 km radius, including Sungai Raya and Sungai Raya Island Districts. This study aims to determine the techno-economic aspect of desalination cogeneration with SMR-type NPP for West Kalimantan. The methodologies in this research encompass a comprehensive literature review, a qualitative assessment of desalination technology, and a quantitative economic analysis utilizing the DEEP version 5.1. Techno-economic analysis shows that simple payback period for MED is 12.3 years, while MSF is 13.9 years. Power lost at MED is 5.3 MWe, while MSF is 9.1 MWe. At a temperature 30.7 °C, the total water cost of the MED is $1.277 $/m3, while MSF is $1.595 $/m3. MED desalination with temperature 70 °C can be effective using residual heat as an energy source. Cogeneration of the MED technology can be option for utilization of heat and power in the context of NPP development in West Kalimantan.
  • Impacts of Award Provision to Improve Nuclear Knowledge Management Program Implementation in a National Nuclear Institution
    Sudi Ariyanto, Siti Komariah
    Aip Conference Proceedings, 2024
    Knowledge is an important asset for a national nuclear institution to ensure the safe, secure, and sustained operation of nuclear facilities. As a result of the government's policy of moratorium on hiring new employees a few yearsago, there was a knowledge gap between seniors and juniors, as well as a potential loss of critical knowledge. Nuclear Knowledge Management (NKM) program is implemented to handle these issues, and it has become a program for the entire organization. The program includes identification and mapping competencies, knowledge documentation, knowledge sharing, knowledge preservation, and Community of Practice development. Program implementation is monitored and evaluated. An intervention activity is carried out in the form of an NKM award provision to improve the quality of the implementation of the NKM program. The scoring is carried out based on criteria covering aspects of Leadership (15%), NKM Program (10%), Human Resource Management (20%), Knowledge Documentation (20%), Knowledge Sharing, and Cooperation (20%), and Innovation (15%). The attributes of the implementation of the NKM program are determined based on an assessment by the BATAN NKM Team. From 2019 to 2020, the intervention of the NKM Award increased the average score of the NKM program implementation, and also increased the number of working units that obtained good and excellent attributes. Furthermore, the effective implementation of NKM provides impacts of real benefits in the form of fulfilling regulatory requirements to produce radiopharmaceuticals in the country, increasing employee qualifications, maintaining employee competence, reducing singleton reliance, and also increasing innovation.
  • Potential of Community Involvement at The Constructions Stage of Nuclear Power Plant Introduction Plan in West Kalimantan

    Aip Conference Proceedings, 2024
    Qualified, specialized, trained, and motivated human resources are required in the construction of nuclear power plants which is categorized as an industry with high technology, complexity, and high risk. Identification of human resources (HR) based on the education of the labour force living around the nuclear power plant prospective site is necessary to assess the potential of involvement of existing human resources. This study aims to assess the potential of HR within a 10 km radius of the demographic-based site reference point at the nuclear power plant construction stage. The methods used include primary and secondary data collection, literature review, and further analysis. The results of the study show that the majority of the population in the assessment area has low education (graduated from elementary school), and mostly has professions as fisherman/farmers. Local HR who have experience working in steam power plants can supply the needs of craftsmen during an NPP construction project, but about 10-20% of craftsmen need to be given basic training in nuclear power and training, in particular in the fields of mechanics and electricity. The population of the labour force with a Bachelor's degree within a radius of 10 km is 3.86%, while those in West Kalimantan Province is 9%. It is known that the capacity of technicians, professionals, supervisors and managers in the area needs to be upgraded. An effort should be taken to improve the qualifications and competencies of the existing HR. The regional government may take a lead in planning and implementing such an effort, in collaboration with the project owner, the local government, the National Research and Innovation Agency as well as the state-owned electricity company. The activities may include the provision of scholarships, training, a talent management program, internship, and other viable modalities.
  • Relaxation process of thermal non-equilibrium in boiling two-phase flow, (I) experimental results
    Ariyanto SUDI, Masanori ARITOMI, Akira MURASE, Kunihiro IWAKI
    Journal of Nuclear Science and Technology, 1994
    Abstract The thermo-hydraulics in a thermal non-equilibrium state, which may appear during a postulated loss-of-coolant accident, is one of phenomena which have never been understood enough. In this paper, accelerating boiling two-phase flow is dealt with which realizes thermal non- equilibrium conditions in a steady state in order to clarify the relaxation process of superheated liquid. The following insight is clarified from the results; Jones' model cannot explain the underpressure and relaxation time unless an empirical constant is changed. Therefore, the effect of interfacial area density on the macroscopic relaxation inception is experimentally investigated by adding artificially bubbles in accelerating boiling two-phase flow in order to offer a fundamental data base for modeling the relaxation process of superheated liquid. It is made clear that the macroscopic relaxation inception can be evaluated by a relationship between the integration of liquid superheating by the travelling time and the initial interfacial area density.
