Experimental devices

Invited Oral

The NSTX Upgrade (NSTX-U) team recently completed a scientifically productive research campaign with 10 run weeks of operation. NSTX-U achieved H-mode on the 8th day of operation, surpassed the maximum magnetic field (achieved Bt = 0.65 T) and pulse-duration (achieved 2 sec long pulse) of NSTX, matched the best NSTX H-mode performance at ~1MA, identified and corrected dominant error fields,...

Fusion reactor needs the steady state operation and sustaining the long pulse operation beyond transient period in term of physics and engineering parameters is essentially one of key requirements in present non DT operation tokamaks.
Recently, KSTAR reported the long pulse operation beyond 1 miniute at the injected power of about 5 MW and the plasma current of 0.5 MA. The normalized beta is...

345. Status of the ITER Vacuum Vessel Manufacturing

Dr C.H. Choi (ITER Organization)

05/06/2017, 11:20

Materials and fabrication

Invited Oral

The ITER Vacuum Vessel (VV) has major functions of being the first confinement barrier and removing nuclear heating during fusion reaction of plasma. Also the VV provide mechanical support for all in vessel components such as Blankets, Divertors, In-vessel Coils, Diagnostics, etc. The VV has been designed as a fully welded torus-shaped, double wall structure with in-wall shielding (IWS) and...

423. MAST Upgrade Divertor Facility: A test bed for novel divertor solutions

Dr William Morris (CCFE, UKAEA)

05/06/2017, 11:40

Divertors and high heat flux components

Invited Oral

The challenge of integrated exhaust consistent with the other requirements in DEMO-class tokamaks (ITER-like and alternative DEMOs, FNSF approaches) is well-known. The exhaust solution is likely to be fundamental to the design and operating scenarios chosen. While no facility can address all of the challenges, the new MAST Upgrade tokamak can explore a wide range of the aspects related to the...

152. Progress of Interface Design between Test Cell and Lithium Systems in IFMIF-DONES

Dr Kuo Tian (Institute for Neutron Physics and Reactor Technology, Karlsruhe Institute of Technology)

Experimental devices

Oral

The Test Cell (TC) in the IFMIF-DONES (International Fusion Material Irradiation Facility- Demo Oriented Neutron Source) facility is the central confinement to envelop the end section of the accelerator, the lithium Target Assembly (TA), and the test modules. The major functions of the TC include: hosting fusion material irradiation experiments in a leak-tight controlled environment, providing...

Fusion energy becomes essential to solve the energy problem with the increase of energy demands. Although the recent studies of fusion energy have demonstrated the feasibility of fusion power, it commonly realizes that more hard work is needed on neutronics and safety before real application of fusion energy. A high intensity D-T fusion neutron generator is keenly needed for the research and...
