The Newcomer's dilemma: Navigating strategic risks in nuclear fuel cycle development a simulation-based framework for Indonesia Suparman Suparman, Djarot Sulistio Wisnubroto, Gagad Rahmadi, Ganisa Kurniati Suryaman Nuclear Engineering and Technology, 2026 This paper presents a comprehensive simulation-driven framework to optimize the nuclear fuel cycle for Indonesia's ambitious 2060 net-zero roadmap. Utilizing the IAEA's INPRO ROADMAPS-ET model, the analysis quantifies the massive material flows required to support a 44 GWe (99-reactors) fleet, including demands for 131,000 tonnes of uranium and the management of nearly 15,000 tHM of spent fuel. More significantly, the analysis moves beyond mere quantification to uncover critical strategic dilemmas. It identifies a "Fabrication Sovereignty Gap" with over 90% import reliance, a "Converter's Dilemma" driven by high market entry barriers, and a "Backend Reality Gap" between optimistic planning and geopolitical realities of waste management. These findings underscore the necessity of a dual-track policy for waste and phased localization for fuel supply. Ultimately, this study provides a replicable analytical framework and a new vocabulary for emerging nuclear nations to assess and navigate the complex trade-offs between sovereignty, security, and economic viability in their decarbonization strategies.
Arc Plasma-Synthesized Graphene Oxide From Coconut Fibers: A Green Adsorbent for Co-60 and Cs-137 Removal From Nuclear Liquid Waste Sriyono Sriyono, Komar Sutriah, Djarot Sulistio Wisnubroto, Geni Rina Sunaryo, Noorshida Mohd. Ali, Dyah Iswantini Chemistryselect, 2026 The management of liquid radioactive waste (LRW) from nuclear facilities is challenging due to the persistence and toxicity of long‐lived radionuclides. This study reports an environmentally friendly synthesis of graphene oxide (GO) from coconut fiber biomass using a catalyst‐free arc plasma technique (> 3000°C), enabling complete carbon conversion and offering a sustainable pathway that leverages Indonesia's abundant biomass resources. The resulting GO was characterized by BET, FTIR, Raman, XRD, SEM, and HR‐TEM. BET characterization showed that the GO possessed an extensive surface area of 3302 m 2 /g with a highly developed porosity, whereas FTIR spectra verified the presence of oxygenated functional groups, including carboxyls, which facilitate ion‐exchange interactions. SEM and HR‐TEM showed uniform morphology and elemental composition dominated by carbon, oxygen, hydrogen, and trace potassium. Batch adsorption experiments with actual LRW from the G.A. Siwabessy reactor demonstrated high removal efficiencies, achieving 98.7% for Co‐60 and 75.6% for Cs‐137. The adsorption kinetics were consistent with a pseudo‐second‐order model, pointing to chemisorption as the dominant pathway, whereas the equilibrium data aligned with the Langmuir isotherm, yielding maximum uptake values of 249.047 MBq/g (Co‐60) and 151.016 MBq/g (Cs‐137). The findings highlight the promise of arc plasma‐derived GO as a green, high‐performance adsorbent for sustainable LRW remediation.
Phytoremediation of cesium-contaminated soils using Sorghum bicolor, Albizia falcataria, Amaranthus viridis, and Vetiveria zizanioides in tropical environments Nuril Hidayati T.H, Gustri Nurliati, Mirawaty Mirawaty, Zeni Anggraini, Raden Sumarbagiono, Sugeng Purnomo, Suryantoro Suryantoro, Ajrieh Setyawan, Moch Romli, Mukhamad Nurhasyim, Sunardi Sunardi, Dyah Sulistyani Rahayu, Suhartono Suhartono, Djarot Sulistio Wisnubroto, Dadong Iskandar, Susetyo Hario Putero, Chalid Talib, Indra Gunawan, Nana Mulyana, Irawan Sugoro, Muhammad Yusuf Nuclear Engineering and Technology, 2026 Radioactive cesium (Cs-137) contamination in soil presents serious environmental and health concerns due to its long-lasting presence and high mobility. Conventional remediation techniques are often expensive and technically complex, prompting the need for more sustainable approaches. This study investigates the potential of phytoremediation as an environmentally friendly approach for soils contaminated with stable isotope Cs-133, using Sorghum bicolor, Albizia falcataria, Amaranthus viridis, and Vetiveria zizanioides under controlled conditions. The results indicate that a mong the four species studied, Amaranthus viridis and Sorghum bicolor achieved the higher bioaccumulation and translocation factors, with Amaranthus viridis producing a peak biomass of 125 g at 100 ppm and Sorghum bicolor reaching 180 g at 50 ppm. All species showed translocation factor values greater than 1, confirming their ability for phytoextraction. However, while bioaccumulation factor values exceeded 1 at cesium concentrations below 50 ppm, they decreased at higher concentrations, suggesting a threshold for effective uptake. These findings indicate that Amaranthus viridis and Sorghum bicolor are promising candidates for phytoremediation of cesium-contaminated soils, particularly at concentrations up to 50 ppm, offering valuable insights into sustainable radioactive waste management, especially in tropical settings.
Indonesia's RDE program: A multifaceted approach to nuclear energy development encompassing human Resource building, public acceptance, and technological innovation Djarot Sulistio Wisnubroto, Geni Rina Sunaryo, Yarianto Sugeng Budi Susilo Nuclear Engineering and Technology, 2025 Indonesia faces the challenge of balancing energy development with environmental conservation. The Experimental Power Reactor (RDE) symbolizes progress toward sustainable energy solutions, reducing reliance on fossil fuels while prioritizing environmental protection. Launched in 2014, the RDE project supports Indonesia's commitment to achieving net-zero emissions by 2060, using nuclear power as a key contributor. It focuses on small-scale High-Temperature Gas-cooled Reactors (HTGR) tailored to local needs, aiming to enhance community engagement and build nuclear expertise. The program includes detailed feasibility studies, site selection, international partnerships, and public outreach. Collaborations with organizations like Tsinghua University and the International Atomic Energy Agency (IAEA) are vital for technical support and capacity building. The RDE highlights the importance of community involvement, strategic global alliances, and developing local expertise to advance nuclear energy in Indonesia. It provides a framework for integrating nuclear power into a broader green energy strategy, supporting regulatory reforms and public engagement. The RDE's approach combines technological innovation with socio-political awareness, positioning nuclear energy as a sustainable part of Indonesia's energy future. This initiative serves as a model for future projects, demonstrating Indonesia's dedication to sustainability and energy security.

Durability study of AlMg2 in high-purity cooling water: A 15-year case from the RSG-GAS nuclear reactor International Journal of Corrosion and Scale Inhibition, 2025 This study presents a long-term corrosion assessment of AlMg2, an aluminum-magnesium alloy extensively used as fuel cladding in nuclear research reactors.The evaluation was conducted after 15 years of uninterrupted exposure in the high-purity primary cooling water of the 30 MW RSG-GAS reactor in Indonesia.The objective was to determine the extent of surface degradation and elemental alteration under chemically controlled conditions.Surface morphology and elemental composition were analyzed using optical microscopy, Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDS).Results indicated minimal corrosion, with pit depths remaining below 5 m and the total affected surface area limited to less than 0.01%.These observations confirm the alloy's high resistance to crevice corrosion.Elemental analysis of the passive oxide layer identified aluminum, oxygen, and magnesium as the dominant constituents, with trace carbon likely originating from postexposure adsorption of airborne hydrocarbons or interaction with atmospheric CO2.The findings affirm the long-term structural integrity and durability of AlMg2 under sustained reactor operation, reinforcing its suitability for application in water-cooled research reactors and prospective small modular reactor (SMR) technologies.
