Experimental test of the system of vertical and longitudinal lithium limiters on T-11M tokamak as a prototype of plasma facing components of a steady-state fusion neutron source

, 2015
A new functional model of the prototype of closed Li circuit for protection of the chamber wall was tested in T-11M tokamak by simultaneous use of the vertical Li limiter as an emitter of Li and a new longitudinal Li limiter as its collector.

Unsteady Mixed Convection Flows in a Rectangular Duct and Dynamical Behaviors of Flow Channel Insert

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
Buoyancy‐assisted upward MHD flows and dynamical behaviors of flow channel insert (FCI) in the dual‐coolant lead‐lithium (DCLL) blanket are studied numerically. Based on our internally developed and validated solver, the dynamical behaviors of magneto‐thermo‐fluid‐structure coupled multiphysical field are investigated. A large amplitude, low frequency,

Structure of chaotic magnetic field lines in IR-T1 tokamak due to ergodic magnetic limiter

AIP Advances, 2018
In this paper we have studied an Ergodic Magnetic Limiter (EML) based chaotic magnetic field for transport control in the edge plasma of IR-T1 tokamak. The resonance created by the EML causes perturbation of the equilibrium field line in tokamak and as a

On the power and size of tokamak fusion pilot plants and reactors

, 2015
It is generally accepted that the route to fusion power involves large devices of ITER scale or larger. However, we show, contrary to expectations, that for steady state tokamaks operating at fixed fractions of the density and beta limits, the fusion ...

Experimental observations of bifurcated power decay lengths in the near Scrape-Off Layer of ST40 High Field Spherical Tokamak

Nuclear Materials and Energy
The scrape-off layer parallel heat flux decay lengths measured at ST40, a high field, low aspect ratio spherical tokamak, have been observed to bifurcate into two groups.

Tailoring tokamak error fields to control plasma instabilities and transport

Nature Communications
A tokamak relies on the axisymmetric magnetic fields to confine fusion plasmas and aims to deliver sustainable and clean energy. However, misalignments arise inevitably in the tokamak construction, leading to small asymmetries in the magnetic field known

Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry

Nuclear Materials and Energy
Plasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MW/m2. The magnitude of these heat loads is set by the width of the channel, the ‘scrape-off layer’
