"没有合适的原料，我们就自己开发。"抚顺特钢技术中心主任助理王树财回忆道，2012年研发之初，中 国科学院上海应用物理研究所团队在确定GH3535合金元素成分的精准配比后，精准控制成分是大生产 冶炼的第一道难关。科研人员在冶炼炉前熬过无数个通宵，记录本上写满了密密麻麻的数据，经过坚持 不懈的试验，最终确立了精准的合金化学成分及控制体系。 成分难题刚破，金属"偏析"问题接踵而至。"所谓偏析，就像炒大锅菜，食材越多越难拌匀，有的地方 咸、有的地方淡，影响了合金的整体性能。"王树财说，这种化学元素的不均匀会直接影响合金的耐蚀 性和强度。由中国科学院上海应用物理研究所、中国科学院金属研究所和抚顺特钢联合组成的团队不断 改善熔炼和扩散退火工艺，最终让合金各部位的成分均匀度达到标准。 本报记者 崔振波 日前，由中国科学院上海应用物理研究所牵头建成的2兆瓦液态燃料钍基熔盐实验堆首次实现钍铀核燃 料转换，成为目前全球唯一运行并实现钍燃料入堆的熔盐堆。钍基熔盐堆是以钍为燃料，以高温熔盐作 为冷却剂的第四代先进核能系统，与目前普遍使用的压水堆不同，无须巨大压力容器，也不用大量水冷 却，就像把核燃料放在高温的盐里流动发电，既安全又 ...
