Abstract TRISO-UN KERNEL FABRICATION AND ITS CHARACTERS, A REVIEW. High temperature nuclear reactors (HTRs) become the future nuclear power reactor due to its ability for electricity generation, hydrogen production and sea water desalination. Uranium nitride (UN) coated with tristructural isotropic (TRISO) coating materials has attracted the researchers because of its similar characteristics to UO2 buat has a higher density. There are beneficial in using UN as fuel due to the longer usage and efficient in refueling. The fabrication of UN kernel, coating of TRISO-UN, and characterics of UN have been reviewed. Among the technology provided for producing UN kernel, atomizing is selected due to its simply and less waste produced. Coating technology used follows the current technology for TRISO-UO2 that is fluidized bed chemical vapor deposition type. Since there are two types HTR fuel, block and ball types, fabrication technique of TRISO-UN fuel depends on the HTR type selected. Keywords: fabrication; coating; UN compound; TRISO-UN   Abstrak Reaktor nuklir suhu tinggi (high temperature reactors, HTR) merupakan reaktor daya masa depan karena dapat digunakan sebagai pembangkit daya listrik, penghasil gas hidrogen dan desalisasi air laut. Bahan bakar nuklir berupa senyawa uranium nitrida (UN) yang dilapisi dengan lapisan tristructural isotropic (TRISO) menjadi topik bahasan akhir-akhir ini. Pengembangan bahan bakar nuklir bentuk kernel UN untuk reaktor HTR dipromosikan karena memiliki karakter yang mirip dengan kernel UO2 namun memiliki densitas uranium lebih tinggi. UN memiliki keuntungan karena waktu pakai di reaktor lebih panjang dan penggantian bahan bakarnya lebih efisien. teknologi pembuatan kernel dan teknologi atomizing menjadi pilihan untuk pembuatan kernel UN karena proses lebih sederhana, waktu lebih cepat dan sedikit menghasilkan limbah. Teknologi pelapisan dan spesifikasi TRISO-UN yang akan dibuat mengikuti teknologi yang sudah terbukti, yaitu fluidized bed chemical vapor deposition type. Bahan bakar reaktor HTR yang ada di dunia ada dua tipe, yaitu tipe blok dan tipe bola, fabrikasi bahan bakar TRISO-UN disesuaikan dengan jenis reaktor yang akan dibangun. Kata kunci: fabrikasi; pelapisan; senyawa UN; TRISO-UN

ABSTRACTThe innovative Combustion Chemical Vapor Deposition (CCVD) process is a non-vacuum technique that is being investigated to enable next generation products in several application areas including high-temperature superconductors (HTS). In combination with the Rolling Assisted Biaxially Textured Substrate (RABiTS) technology, the CCVD process has significant promise to provide low-cost, high-quality lengths of YBCO coated conductor. The CCVD technology has been used to deposit both buffer layer coatings as well as YBCO superconducting layers. A buffer layer architecture of strontium titanate and ceria have been deposited by CCVD on textured nickel substrates and optimized to appropriate thicknesses and microstructures to provide templates for growing PLD YBCO with high critical current density values. The CCVD buffer layers have been scaled to meter plus lengths with good epitaxial uniformity along the length. A short sample cut from one of the lengths enabled high critical current density PLD YBCO. Films of CCVD YBCO superconductors have been grown on single crystal substrates with critical current densities over 1 MA/cm2. Work is currently in progress to combine both the buffer layer and superconductor technologies to produce high-quality coupons of HTS tape made entirely by the non-vacuum CCVD process.
