CCN Meeting in 2010

• 15 participants (with data users D. Coster and D. Elder)• Valuable exchange of information on data production and applications

• Flexible group of participants• Utilize CCN as a network for the coordination and collaboration on code activities

• Larger network with diverse background desirable • codes, models, experiments

• Concerns over the uncertainties of on-line code calculations • More harm to have online codes without the expert help

• Better to host expert-generated data

• An integrated database of recommended data and code capabilities• A database based on the decision tree concept proposed

• The quality and availability of data sets should be provided for a data inquiry

• CCN activities should be formulated to benefit code developers directly• Code comparison workshops (eg. NLTE7)

IAEA

Coordinated Research Projectshttp://www-amdis.iaea.org/CRP/

2008-2012: Characterization of Size, Composition and Origins of Dust in Fusion Devices

2009-2013: Light Element Atom, Molecule and Radical Behaviour in the Divertor and Edge Plasma Regions

2010-2014: Spectroscopic and Collisional Data for Tungsten from 1 eV to 20 keV

2011-2015: Atomic and Molecular Data for State-Resolved Modelling of Hydrogen and Helium and Their Isotopes in Fusion Plasma

2012-2016: Data for Erosion and Tritium Retention in Beryllium Plasma-Facing Materials

2013-2017 (tentative): Plasma-material Interaction for Irradiated Tungsten and Tungsten Alloys

2015-2019 (tentative): Plasma Interaction with Low-activation Stainless Steel Surfaces

IAEA

2012-2016: Data for Erosion and Tritium Retention in Beryllium Plasma-Facing Materials

http://www-amdis.iaea.org/CRP/Beryllium/

Processes include physical and chemical sputtering and trapping and transport of hydrogen (H,D,T) for beryllium-based surfaces. The CRP will emphasize data for the relevant mixed materials, especially Be-(H,D,T,He), Be-C, Be-N, Be-O. The most important projectiles are H, D, T, He, Be, C, N, O, Ne and Ar.

The first RCM was held 26-28 Sep 2012.

Comments (BJB):

Experimental database is basically PISCES.

Theoretical database is basically Eckstein’s BCA (“TRIM”) data.

This is all a bit limited relative to the importance of the subject. Beryllium should be the ideal material for large scale computational work.

IAEA

2013-2017 (planned): Plasma-material Interaction for Irradiated Tungsten and Tungsten Alloys

This CRP is in the Programme and Budget to start in 2013.

Overall objective: To enhance the knowledge base on interaction of H and He in plasma with tungsten-based plasma-facing materials in the nuclear environment of a fusion reactor.

Tritium retention and tritium removal may be strongly influenced by radiation damage and alloy formation. The CRP must include study of the effects of irradiation on surface microstructure.

IAEA

Possible follow-up to Light Elements CRP

• CRPs are “fully booked” until 2015, with focus on PMI.

• Assembly, evaluation and recommendation of data for beryllium in plasma.• Processes of Be, BeH and BeH2 and their ions in edge plasma.

• Fusion conditions, data and data evaluation for the needs of fusion plasma modelling and diagnostics.

• Not a CRP; can have a Consultant Meeting (CM) or small Technical Meeting (TM).

• Data for neutral beams in plasma• This may be a good topic for a somewhat larger TM.• Neutral beams are mainly H, He, Li; possibly Na.• Computational and diagnostics aspects
