In the Pre-Concept Design Phase of EU-DEMO, work package TFV (Tritium – Matter Injection Vacuum) has developed a tritium self-sufficient three-loop fuel cycle architecture. Driven by need to reduce inventory in systems an absolute minimum, this requires continual recirculation gases loops without storage, avoiding hold-ups each process stage giving preference continuous over batch technologies, and immediate use extracted from breeding blankets. order achieve goal, number novel concepts...
Experimental findings to contribute the preliminary design of a metal foil pump for fuel separation in Direct Internal Recycling loop DEMO fusion device are presented. In parametric studies on small-scale superpermeation experiment with microwave plasma source and two different materials, niobium Nb vanadium V, substantial increase permeation power decrease pressure was observed. To ease operation typical environment, in-situ heating procedures were developed recover from impurity...
In the DEMO Pre-Concept Design Phase, a novel fuel cycle architecture has been developed that aims at reducing tritium inventory of plant. contrast to previous designs, central role thereby is taken by an additional direct internal recycling loop. By already separating significant proportion pumping duct and providing this purified gas almost directly injection systems, load on plant as well overall reduced substantially. This paper summarizes activities conducted in regard integration...
Any good design of fuel cycles for thermonuclear fusion reactors, which operate on deuterium-tritium fusion, comes with minimized tritium inventory. The direct internal recycling concept can significantly reduce the inventory a power plant by introducing bypass most unburned from torus exhaust. It requires technology that sharply separate hydrogen isotopes other gases in given environment reactor's pump duct. prime candidate this task is metal foil (MFP) using plasma-driven permeation. A...
It is a challenging but key task to reduce the tritium inventory in EU-DEMO levels that are acceptable for nuclear regulator. As solution this issue, smart fuel cycle architecture proposed based on concept of Direct Internal Recycling (DIR), which Metal Foil Pump (MFP) will play an important role separate unburnt hydrogen isotopes coming from divertor by exploiting superpermeation phenomenon. In study, we present assessment performance lower port after integration MFP. For first time,...
