17th Meeting of the International Network of Nuclear Structure and
Decay Data Evaluators, 11-15 June 2007
Data services, data networks and user support
1.
Collect accurate and up-to-date atomic and nuclear data,
and disseminate to satisfy the needs of users from Member
States
2.
Co-ordinate networks of national and regional data
centres, and promote the exchange of atomic and nuclear
data for various applications
3.
Maintain manuals and software for internationally-agreed
database formats and exchange procedures
4.
Improve the methods of providing information to data
users, and provide training in the effective use of atomic
and nuclear data through workshops

International Atomic Energy Agency
Nuclear data standards and evaluation methods
Enable users to produce evaluated nuclear data that
satisfy the high accuracy and consistency demanded
by emerging nuclear technologies through the
production of clearly defined evaluation methods and
procedures
- CRP on “Improved Cross-Section Standards”
assemble and publish technical report, 2006-07
- maintain international neutron cross-section
standards file and associated evaluation
techniques (Special Service Agreement)
- continuation of CRP on “RIPL-3”, 2003-08; final
RCM in 2007
International Atomic Energy Agency
Nuclear data for radiotherapy using
radioisotopes and external radiation sources

Results:
1. Successfully schooled 82 students from 29 countries
2. 21 students have gone on to be mentored by the NSSD
Evaluators’ Network to evaluate mass chains …………….
also a success in finding new blood, albeit sometimes
only on a temporary basis
3. Hope to organize more workshops of this type in the
foreseeable future
