In the last years, CIEMAT worked in the development of a low temperature DCLL breeding blanket design aimed at using conventional materials and technologies. It followed the multi-module segment (MMS) approach, which allows operating within the thermal range tolerated by EUROFER while keeping a low bulk velocity of the self-cooled liquid breeder (PbLi) in the breeding zone. Thinking in the commercial exploitation of fusion, it must be taken into account that there is risk that the foreseen availability goal in fusion reactors is not achieved. In that case, the limited net efficiency of low temperature blankets could not be sufficient to obtain a competitive cost of the electricity. For that reason, more advanced blanket solutions are being explored with the objective of developing a simpler, more reliable and more efficient design based on a single-module segment (SMS) architecture and the use of self-cooled incompressible liquid breeder. In this work, different strategies to solve interrelated aspects like the topology and electrical insulation of the breeder circuits, the first wall integration and the main neutronic responses are analysed and discussed.

在过去的几年中，CIEMAT致力于使用常规材料和技术开发低温DCLL育种毯设计。它遵循了多模块段（MMS）的方法，该方法允许在EUROFER允许的温度范围内运行，同时在繁殖区保持自冷液体育种器（PbLi）的较低整体速度。在对聚变的商业开发中进行思考时，必须考虑到存在无法实现聚变反应堆中可预见的可用性目标的风险。在那种情况下，低温毯子的有限净效率不足以获得具有竞争力的电力成本。因此，我们正在探索更高级的毯式解决方案，以期开发出一种更简单，基于单模块段（SMS）架构和使用自冷却不可压缩液体育种剂的更可靠，更高效的设计。在这项工作中，分析和讨论了解决相互关联的方面的不同策略，例如繁殖电路的拓扑和电绝缘，第一壁集成和主要中子响应。
