IAEA

The 20th DCN Meeting 2009

• All data centres presented progress reports on their activities in A+M data for fusion in the period October 2007 – August 2009 : data compilation, evaluation and generation, web developments, publications

• Observer presentations ITER representative : requirements for modeling ITER and the main new data needs Clark: IAEA Code Centre Network Ralchenko: XSAMS: (XML Schema for AM/PSI Data Exchange)

• The long-term Priorities in A+M and PMI Data Needs for Fusion Energy research were reviewed.

• The importance of data evaluation (accuracy, uncertainties) and traceability was emphasized over and over.

• The DCN supports the development of XSAMS (XML Schema for Atoms, Molecules and Solids) as a reliable and convenient tool for AM/PMI data exchange and many of the data centres are ready to use.

• GENIE continually evolves to search new available databases on the web. The scope of GENIE should be enlarged to more processes and to molecular data.
