Within the framework of EUROfusion Program, Dual Coolant Lithium Lead (DCLL) is one four EU breeder blanket concepts that are being investigated as candidates for DEMO. DCLL uses PbLi main coolant, tritium breeder, carrier, and neutron multiplier. The structures, including first wall, cooled with helium. program proposed next years will consider a version limited to 550 °C in order allow use conventional materials technologies. During year activities, draft design has been proposed....

During the last years CIEMAT has been leading activities in European Program to develop an integral breeding blanket with advanced performances work a realistic DEMO scenario. This is dual coolant lithium lead (DCLL) working at limited temperature order allow use of conventional materials and technologies. The design this was finished, including definition tritium extraction system simulations. Then, determined by selection other two concepts as driver blankets for DEMO, focus put on...

Abstract There is no doubt about the interest of achieving as fast possible capability to build and operate high performance reactors that finally allow fusion competing in electricity market. An advanced breeding blanket based on Dual Coolant Lithium Lead concept with single module segment architecture, designed for European DEMO, certainly aligned such objective. This work describes some recent outcomes efforts carried out framework Prospective R&D Work Package EUROfusion develop this...

Advanced stellarators require convoluted modular coils to produce a plasma with satisfactory performance. Moreover, the number of is sometimes high decrease ripple created by coils. For reactor stellarators, these requirements imply relatively small ports for in-vessel access and maintenance, i.e. in comparison tokamaks. The blankets divertor modules will have be replaced periodically (about each 1-4 years depending on design) due neutron damage, also erosion targets. Blanket are activated,...

Magnetohydrodynamic (MHD) processes are known to be critically important for the dual coolant lithium lead (DCLL) breeding blanket (BB) concept. In order minimize MHD pressure drop in European DCLL design, liquid metal breeder (PbLi) is decoupled electrically from ferritic–martensitic structure (EUROFER) using insulating ceramic-based flow channel inserts (FCIs). The impact of FCI on velocity profile and front poloidal channels studied. Two-dimensional momentum induction equations fully...

Tritium recovery is one of the major issues a future DEMO reactor, in order to comply with requirements tritium self-sufficiency. Within EUROfusion Programme permeation against vacuum (PAV) technique has been considered as baseline for those blankets which use PbLi breeder. A conceptual design rectangular multi-channel PAV its implementation an experimental loop, under construction at CIEMAT, produced. comparison between vanadium/niobium/tantalum and α-Fe membranes performed terms costs,...

Since the advent of wavelength division multiplexed optical systems, increasing bit rate per carrier has proved to be most effective method drive overall cost systems down. However, multicarrier approaches have gained momentum for 400-Gb/s transport cope with bandwidth limitations optoelectronic components. In this paper, single modulated over transatlantic distances is demonstrated first time. Using high-speed digital-to-analog converters, we successfully generated a 64 GBaud...

During the pre-conceptual design phase of DEMO, different alternatives have been explored to be implemented as tritium extraction and removal system (TERS) for blanket concepts considered in EUROfusion. The TERS is conceived extract from breeder route it Tritium Plant final processing. A careful review showed that those blankets operated with PbLi should use permeation against vacuum (PAV) technique primary option which based on a one-step, fully continuous procedure. In this paper,...
