• Experimental evidence indicates that transport of
  various quantities in magnetically confined
  fusion plasmas often exhibits a non-diffusive
  character.
• This transport appears to be well modeled in
  terms of fractional differential equations
  (CTRW).
• Several techniques have been developed to
  characterize non-diffusive transport in (mainly
  electrostatic) numerical simulations of
  turbulence.
• In this project, we will apply these techniques
  to the transport characterization of magnetic
  turbulence driven by tearing modes in a reversed
  field pinch.

• Numerical evidence suggests that transport across
  sheared flows is affected more profoundly that
  previously thought.
• Not only is transport reduced, but its nature
  changes, no longer being well described in terms
  of usual diffusion.
• In this project, we will apply different
  techniques to the characterization of transport
  across sheared flows in tokamak turbulence using
  both fluid and gyrokinetic simulations.

The use of Oxide Dispersion Strengthened (ODS)
Reduced Activation Ferritic Steels (RAF) steels
together with other Tungsten and Titanium alloys
have been proposed as structural materials in
fusion reactor applications. The manufacturing
route and the involved parameters mean a key
point in the development of suitable materials,
i.e. with high strenght at high operating
temperatures. So, a detailed study in both
preparation and characterization of candidate
materials needs to be fulfilled.

The objectives of the present Project
are 1-Material production via powder metallurgy
techniques mechanical alloying, Hot Isostatic
Pressing (HIP), forging, etc. and the selection
of the optimised conditions. 2-Mechanical
characterization of the obtained materials
microstructure (by electron microscopy
techniques), micro and/or nano hardness, tensile
properties, Charpy impact properties, etc.
