The IFMIF-DONES Facility is built with the purpose of irradiating materials under DEMO Tokamak-like conditions and a first-of-a-kind project that foreseen to be in Granada, Spain. A systematic top-down approach used design its Systems aid harmonization interaction between them. One these main systems Test which serves as meeting point for other major such Lithium System (LS) Accelerator (AS), while also providing connection Facilities Complementary Experiments (FCE) additional irradiation...

On a Wendelstein 7-X (W7-X), an alkali metal beam (AMB) diagnostic system was installed in order to measure the plasma edge electron density profiles and turbulence transport. A sodium injected plasma, light emission observed by optical system. During last operation phase, OP1.2b campaign trial spectral measurements were performed with dedicated branch. The results showed emergence of potential CX lines spectra during injection. identified as Carbon III, which dominant other diagnostics at...

Large port-based tokamaks for energy production are expected to be developed around breeding blanket technology, the purpose of which is breed Tritium, provide shielding vessel walls, and carry heat transfer loops. These blankets split into five segments in every torus section [1], each weighing up 60 tons, will require periodic replacement through Upper Port maintenance. During replacement, need guided vacuum highly restricted kinematic paths avoid collisions. A Two Remote Handling approach...

The analysis of the gas expansion in test bench ITER DMS Support Laboratory is discussed. For this purpose, numerical FEM simulations were performed during design phase laboratory. These are compared with experimental data, that have been obtained after construction was finished. and results found to agree well. Both indicate emergence pressure waves acceleration barrel. contribute pellet detachment from barrel wall. Supersonic velocities also observed simulations, an indirect indication for...

The international fusion materials irradiation facility-DEMO-oriented neutron source (IFMIF-DONES) is a facility that designed under the framework of EU roadmap. It going to be an essential for testing and qualifying candidate severe conditions field having energy spectrum like one present in power reactor. material specimens are irradiated containment structure named test cell (TC), which part systems (TS). TC also houses other major system (lithium system, LS), provides liquid lithium...
