Perapuhan Uranium dengan Metode Hydride–Dehydride: Meningkatkan Efisiensi Bahan Bakar Nuklir dalam Mendukung Transisi Energi
No full textThe Hydride–Dehydride (HDH) method is a critical technology in uranium processing, capable of improving the efficiency and quality of nuclear fuel through a more precise embrittlement process compared to conventional techniques. This technology ensures uniform particle size and minimizes material loss during fabrication. This study was conducted using a literature review approach, supported by experimental data obtained during a 2022 internship at the Research Center for Nuclear Fuel Cycle and Radioactive Waste Technology (PRTDBBLNR). The focus of the investigation was the characterization of uranium–molybdenum (U-Mo) alloy before and after the HDH treatment process. The results indicate that heat treatment at 500 °C for 5 hours followed by annealing significantly increases the hardness of the U-Mo alloy. A phase transformation was also observed, indicated by the presence of α-U in all post-treatment samples. Nevertheless, the density of the alloy showed no substantial change. The HDH process successfully produced high-purity U-Mo powder at various molybdenum concentration levels. However, increasing Mo content resulted in lower powder density. The morphology of U-7Mo powder exhibited flake-like shapes with a rough surface, which is favorable for further fabrication in advanced fuel element production. Overall, these findings reinforce the relevance and significant potential of HDH technology in supporting advanced nuclear reactor fuel production and strengthening national nuclear energy security in a sustainable manner.The Hydride–Dehydride (HDH) method represents an important innovation in uranium processing to improve the efficiency and quality of nuclear fuel. This technology enables a more precise embrittlement of uranium compared to conventional methods such as milling and crushing, resulting in more uniform particle size and reduced material loss throughout the process. This study adopts a literature-based approach supported by practical work conducted at the Center for Research on Nuclear Fuel Cycle Technology and Radioactive Waste Management (PRTDBBLNR) in 2022, in order to evaluate the effectiveness of HDH in strengthening nuclear energy security in Indonesia. The analysis shows that HDH improves the microstructural quality of uranium and enhances processing yield by minimizing waste generation. These advantages highlight the high relevance of HDH technology in supporting the development of Generation IV nuclear reactors, which emphasize efficiency and sustainability within the fuel cycle. However, its implementation in Indonesia still faces challenges, particularly in terms of industrial infrastructure readiness, safety regulations, and nuclear material protection. Therefore, strategic policies are required to promote further research and technological investment, as well as strong collaboration between academia, government, and industry. Integrating HDH into the national uranium processing roadmap has the potential to establish this technology as a key pillar in ensuring a sustainable nuclear fuel supply and enhancing Indonesia’s energy security in the future.Metode Hydride-Dehydride (HDH) merupakan inovasi penting dalam pemrosesan uranium untuk meningkatkan efisiensi dan kualitas bahan bakar nuklir. Teknologi ini memungkinkan pengerjaan uranium secara lebih presisi dibandingkan metode konvensional seperti milling dan crushing, sehingga menghasilkan ukuran partikel yang lebih seragam dan mengurangi kehilangan material selama proses. Studi ini menggunakan pendekatan studi literatur yang diperkuat oleh hasil kerja praktik di Pusat Rekayasa dan Teknologi Deteksi Bahan Bakar Lanjut dan Non-Reaktor (PRTDBBLNR) pada tahun 2022, guna memberikan efektivitas HDH dalam mendukung ketahanan energi nuklir di Indonesia. Hasil analisis menunjukkan bahwa proses HDH mampu meningkatkan kualitas mikrostruktur uranium serta memperbaiki hasil pemrosesan dengan meminimalkan limbah. Keunggulan ini menjadikan HDH sangat relevan untuk mendukung pengembangan reaktor nuklir Generasi IV yang fokus pada efisiensi dan pembuangan siklus bahan bakar. Meskipun demikian, penerapannya di Indonesia masih menghadapi tantangan, khususnya terkait kesiapan infrastruktur industri, regulasi keselamatan, serta perlindungan bahan nuklir. Oleh karena itu, diperlukan strategi kebijakan yang mendorong penelitian lanjutan dan investasi teknologi, serta kolaborasi erat antara ilmuwan, pemerintah, dan industri. Dengan integrasi HDH ke dalam peta jalan penyediaan uranium nasional, teknologi ini berpotensi menjadi pilar utama dalam memastikan ketersediaan pasokan bahan bakar nuklir dan memperkuat ketahanan energi Indonesia di masa depan

Decarbonizing Indonesia’s Nickel Smelters: Implications for Energy Security, Carbon Pricing, and Green Finance Policies
Get PDFAs the world’s largest nickel producer, Indonesia faces critical challenges in decarbonizing its nickel smelting sector while maintaining economic growth. This study addresses the lack of integrated assessments of carbon pricing impacts and green finance mechanisms in Indonesia’s nickel industry, using exclusively secondary data from government reports (BPS, MEMR), global databases (IEA, Global Carbon Atlas), and policy documents. A gate-to-gate Life Cycle Assessment (ISO 14044) reveals that Indonesian nickel smelters emit 14.8 tons CO₂-eq per ton of product (IEA, 2023), 25% higher than the global average. Economic modeling, based on nickel price trends (LME, 2020–2023) and carbon tax scenarios, indicates that a $40/ton CO₂ tax would raise production costs by 15%, reducing export competitiveness by 6.2% under current market conditions. Policy analysis highlights the feasibility of green bonds and fiscal incentives for renewable energy adoption, referencing successful cases in the Philippines (RE Law, 2022). These findings provide a data-driven framework for aligning Indonesia’s nickel industry with its 2060 net-zero target, emphasizing the role of secondary data in shaping low-carbon transitions for resource-rich economies
