FFUSION2 - Technology Programme

• The objective is to develop technology with
  Finnishindustry for international fusion
  projects as a fullyintegrated partner in the
  European Fusion Programme.The ultimate goal is
  harnessing fusion energy.

• Programme duration 1999-2002
• Programme volume 15 million euros
• Programme Manager Seppo Karttunen, VTT

FFUSION2 cooperation

• The FFUSION2 Programme is fully integratedinto
  the European Fusion Programme by theContract of
  Association(Association Euratom-Tekes)
• Multilateral European Fusion DevelopmentAgreement
  (EFDA) covers the JET activitiesand Technology
  Programme for ITER andlong-term European RD
• Association Euratom-Tekes participatesactively
  in the joint European experiments(JET, ASDEX-U)
  and in the research anddevelopment work for
  ITER. Finnish industryis involved in the fusion
  technology work.

ITER - International Tokamak Experiment

• The goal of ITER is to demonstratescientific and
  technical feasibilityof fusion energy production
• Final design has been completedand negotiations
  on site and costsharing are underway
• Canada, France, Spain and Japanhave proposed
  sites for ITER
• Direct construction cost is 3.5billion euros
• Decision on construction isexpected in 2003-2004

• ITER is a tokamak-type fusiondevice with thermal
  fusion powerof 500 MW. The reference pulseis
  400 sec long, but ITER isdesigned for
  steady-stateoperation, too. Heating poweris
  50-100 MW.

Objectives
The global goal is to develop fusion power as a
environmentallyfriendly, safe and economically
viable energy source for mankind

• Programme objectives
• To produce high-quality science andnew
  technology in our focus areas tothe European
  Fusion Programme
• To promote collaboration betweenresearch
  institutes and industry inpreparing for ITER
  construction
• To provide Finnish technology to ITERand benefit
  from the technology transferand spin-offs from a
  large internationalprogramme

Research Results 1

• Over 100 publications dealingwith plasma
  heating, transportphenomena and MHD stabilityof
  fusion plasmas. Most of thework is carried out
  in collabo-ration with European tokamaksJET,
  ASDEX-U and Tore Supra(VTT, Helsinki University
  ofTechnology).
• Development of plasma facing coatings,surface
  analysis and molecular dynamicsimulations have
  considerably deepenedthe understanding of plasma
  surfaceinteractions (VTT, University of
  Helsinki)
• Diarc Technology provided tungstencoated
  divertor tiles which were tested and installed
  into JET

JET - Joint European Torus

• JET is the joint European fusionexperiment in
  Culham, UK.
• JET is the most powerful fusiondevice in the
  world having theworld record fusion power of16
  MW

• The Tekes Association isactively involved in the
  JET workprogram-me carrying out
  scientificco-ordination, modelling and
  dataanalysis of JET experiments. Thework covers
  the internal transportbarriers, radio-frequency
  heatingand plasma-wall interactions.
