| 中文摘要 | 在聚变堆初步概念设计的基础上,针对固态包层设计路线,提出了一个先进的氦冷固态包层概念。设计采用Be_(12)Ti和Li_2TiO_3陶瓷小球混和球床,物理和化学相容性好;采用SiC作为结构材料,提高耐高温性能及氦气出口温度。计算结果表明:选择Be_(12)Ti和Li_2TiO_3球体积比在2和4之间较合理;在Be_(12)Ti和Li_2TiO_3球体积比为3时~6Li富集度取30%～80%较适宜;球床的最高温度低于材料的温度限值,温度分布合理均匀。该方案可较大程度提高热效率和改善中子学以及氚增殖性能。; Based on the preliminary design of fusion reactor,aiming at the outline of solid blanket design,an advanced helium cooled solid blanket concept was developed. Be_(12)Ti and Li_2TiO_3 mixed pebble bed as neutron and tritium breeder which has high compatibility was adopted,and SiC as structure material which can endure high tempera- ture for increasing the temperature of helium outlet.Calculation results show that the volume ratio of Be_(12) Ti and Li_2 TiO_3 should properly approximate between 2 and 4.In case of selecting 3 as volume ration of Be_(12) Ti and Li_2 TiO_3, ~6Li enrichment ranged between 30%and 80%is suitable.The maximum temperature in the pebble bed is below the limited temperature of blanket material,and temperature distribution is rea- sonable properly uniform.This scheme can improve the thermal efficiency as well as neutronics and tritium breeding performance. |
