Thermochemcial characteristics of powder fabricated using oxidation treatment of spent PWR fuel and SIMFUEL were evaluated for recycling of spent fuel such as DUPIC process. Especially, the influence of spent fuel burn-ups on the powder fabrication characteristics was experimentally evaluated, ranging from 27,300 to 65,000 MWd/tU. Densities of powder manufactured from an oxidation, OREOX and th...

CASK (Ca2+/calmodulin-activated serine kinase) is a synaptic protein that interacts with the cytosolic tail of adhesion molecules such as neurexins, syncam and syndecans. It belongs to the MAGUK (membrane-associated guanylate kinase) family of scaffolding proteins which are known to decorate cell-cell junctions. CASK is an essential gene in mammals, critical for neurodevelopment. Mutations in t...

The rapid consumption of petroleum deposits and the escalating air pollution problems caused by burning fossil fuels have driven the global research community to look for cleaner and renewable energy resources. Albeit not a primary energy source, hydrogen is an ideal energy carrier. It almost triples the gravimetric heat of combustion of gasoline (120 MJ kg 1 vs. 44.5 MJ kg ). More importantly,...

A numerical simulation of flow and heat transfer in a ventilated concrete dry storage cask system–17 (VSC–17) is performed and results compared with experimental data to assess the validity of the computational approach. The measurements of steady state temperature distributions on the cask surface, concrete surface, air flow channels, and fuel canister guide are available. Numerical simulation...

Biofuels that are produced from biobased materials are a good alternative to petroleum based fuels. They offer several benefits to society and the environment. Producing second generation biofuels is even more challenging than producing first generation biofuels due the complexity of the biomass and issues related to producing, harvesting, and transporting less dense biomass to centralized bior...

Previous Advanced Fuel Cycle Initiative (AFCI) studies were made to assess the effects of the existing accumulation of LWR spent fuel in the United States on the capability to partition/transmute actinides using existing and advanced LWRs. The concept of treating the “oldest fuel first” indicated that significant advantages could be gained in both partitioning, transmutation, and in overall cos...

The operating license of Kori units 3 and 4 are to be expired in 2024 2025. If the plants decided decommissioned, spent nuclear fuels fuel storage pool (SFP) have removed from site. However, no proper facility is currently available Korea. To overcome difficulty, this study proposes application an independent temporary SFP cooling system. It expected safely isolate plant. case conducted showed ...

In this paper, the transmutation of TRUs of the DUPIC (Direct Use of Spent PWR Fuel in CANDU) spent fuel has been studied with the HYPER system, which is an LBE-cooled ADS. The DUPIC concept is a synergistic combination of PWRs and CANDUs, in which PWR spent fuels are directly reutilized in CANDU reactors after a very simple re-fabrication process. In the DUPICHYPER fuel cycle, TRUs are recover...

A study of the DUPIC (Direct Use of Spent PWR Fuel In CANDU) cycle was made to analyze cycle performance relative to that of PWR and CANDU fuel cycles in terms of uranium utilization and spent fuel production efficiency. The DUPIC cycle was found to be most efficient in terms of minimizing spent fuel production as well as most efficient (within limits) in terms of maximizing natural uranium uti...
