本文描述了高温气冷堆用的u0。燃料芯核的溶胶一凝胶法制造过程。它采用脲素络合硝酸铀酰制备胶体,用聚乙烯醇及四氢糠醇调节溶胶性质,通过振动喷嘴分散成滴在氨水柱中造粒。对溶胶喷射流均一造滴的条件进行了研究。
This article describes u0 for high-temperature gas-cooled reactors. Fuel-core nuclear sol-gel process. The preparation method comprises the following steps: preparing urea by uranyl complex uranyl nitrate, adjusting the sol property by using polyvinyl alcohol and tetrahydrofurfuryl alcohol, and dispersing the solution into granulated ammonia in a ... ... ammonia column through a vibrating nozzle. The condition of droplet formation by sol jet was studied.
