There are currently 4 active nuclear power stations (NPS) and 13 operational VVER energy units, producing a total power of 11880 MW, in the country. According to the data collected from the International Agency of Nuclear-Power Energy, Ukraine is in seventh place for the largest supply of uranium on the planet. The use of nuclear power in Ukraine includes: extraction and processing uranium ore, production of UF6, production of zirconia rental and purveyances from a zirconia alloy, production of heat-radiating collections, storage of exhaust nuclear fuel and nuclear wastes. The realisation of uranium isotopic enrichment is the main problem in the structure of organisation in nuclear fuel production in Ukraine. This country has a unique station, non-operative Chemobyl NPS, where different types of wastes are located. Two factories are currently being built there in order to process the liquid and solid radio-active wastes. In perspective, Ukrainian nuclear-power energy will be enriched with new nuclear-power units and security systems to ensure safe manufacturing.展开更多

A pilot plant for cellulosic ethanol production with a capacity of one ton in dry biomass per day was established in 2007 and launched test-run operations for mass production in early 2010. The feedstock is focused on rice straw currently, but is also flexible for sugarcane bagasse and hardwood. The operative experiences and the experimental data will provide valuable information for the evaluation of production cost as well as the foundation for design of a commercial production plant in Taiwan. Additionally, this pilot plant will also serve as an important platform for validation of technologies related to cellulosic ethanol production and biorefinery operations. The biomass-to-ethanol process of this plant is based on the route of biochemical conversions. Developed and developing technologies, such as acid hydrolysis pretreatment, high solid to liquid ratio hydrolysis, in-house cellulase production, xylose fermentation, and the distillation and dehydration processes will be introduced.展开更多
