摘要
韩国(KO)开发了液体增殖毯,并参与了国际热核实验反应堆(ITER)小组的测试毯模块(TBM)项目,该项目具有氦冷却熔融锂(HCML)概念。基于这一概念,氦(He)和液态锂(Li)分别被用作冷却剂和增殖剂。此外,铁素体马氏体(FM)钢被认为是一种结构材料。然而,根据我们开发液体增殖剂TBM的策略及其更相关的DEMO概念,不仅考虑了液体锂增殖剂,还考虑了铅锂(PbLi)增殖剂。为了验证我们的电磁(EM)泵的设计和制造,构建了液体增殖器(ELLI)的实验环路;测试磁流体动力学(MHD)的效果;用铁素体马氏体钢等结构材料研究PbLi的相容性。在ELLI中,以Li为15.7 at %(以下称为PbLi)的Pb-15.7Li作为繁殖材料,EM泵使其通过回路循环。回路最大工作压力为0.5 MPa,最大工作温度为550℃。在本研究中,对电磁泵进行了性能测试。在三个单独的实验中,EM泵以0.16 m/s的速度运行250 h进行腐蚀测试。针对一种腐蚀试验材料,制作了管状和圆柱状试样,分别安装在环形试验槽的三个试验槽中。在将样品安装到回路中后,EM泵在340℃下以0.16 m/s的流速运行250小时,进行腐蚀测试。
Performance tests of an Experimental Loop for Liquid breeder in Korea
Korea (KO) has developed a Liquid breeder blanket and participated in the Test Blanket Module (TBM) program within the International Thermonuclear Experimental Reactor (ITER) group with a Helium Cooled Molten Lithium (HCML) concept. Based on this concept, helium (He) and liquid lithium (Li) were used as a coolant and breeder, respectively. Additionally, ferritic martensitic (FM) steel was considered as a structural material. However, according to our strategy for developing a liquid breeder TBM and its more relevant DEMO concept, not only liquid lithium breeders, but also lead-lithium (PbLi) breeders were considered. An Experimental Loop for a Liquid breeder (ELLI) was constructed for the purpose of validating the design and fabrication of our electromagnetic (EM) pump; testing the effects of the magneto-hydro-dynamics (MHD); and investigating the compatibility of PbLi using structural materials such as ferritic martensitic steel. In the ELLI, Pb-15.7Li, where Li is 15.7 at % (called PbLi hereafter), is used as the breeding material, and the EM pump circulates it through the loop. The maximum operating pressure and temperature in the loop are 0.5 MPa and 550 °C, respectively. In this study, performance tests with the EM pump were carried out. During the three separate experiments, the EM pump was operated for 250 h with a speed of 0.16 m/s for corrosion tests. For a material of corrosion test, tubular-type specimens and cylindrical-type specimens were fabricated and installed in three test pots of the loop. After installing the specimens into the loop, the corrosion test was performed while the EM pump was operating with a 0.16 m/s flow rate at 340 °C for 250 h.
