Description
Water-Cooled Lithium-Lead Breeding Blanket (WCLL) is considered a candidate option for European DEMO reactor. Starting from previous experiences in the frame of Power Plant Conceptual Studies within EUROfusion Consortium, , ENEA and its linked third parties have proposed and are developing a multi-module blanket segment concept based on DEMO 2015 specifications. The layout of the module is based on horizontal (i.e. radial-toroidal) water cooling tubes in the Breeding Zone (BZ), and on Lithium Lead (PbLi) flowing in radial-poloidal direction. This design choice is driven by the rationale to have a modular design, where a basic geometry is repeated along the poloidal direction of the segment. The modules are connected with a back supporting structure, designed to withstand thermal and mechanical loads due to normal operation and selected postulated accidents. Water and PbLi manifolds are designed and integrated with a consistent primary heat transport system (PHTS), based on a reliable pressurized water reactor (PWR) operating experience, and the PbLi system. The pulsed operation of DEMO is addressed thanks to the adoption of a molten salt system. Rationale and features of current status of WCLL BB design are discussed and supported by thermo-mechanics, thermo-hydraulics and neutronics analyses. Open issues and areas of R&D needs are finally pointed out.
