Nuclear Safeguards (major part of budget) The Nuclear ‘Police’ Force... negotiates protocols and
makes inspections Support for Peaceful Uses of Atomic Energy
Documentation to provide guidance to Member States... NOT to make policy or to prescribe procedures

We seek to learn from the
behaviour of existing graphites how new
graphites will behave and how existing
graphites will perform at fluences we have not
yet reached
THE KNOWLEDGE BASE: A HISTORY (1)
1995: issue of potential ‘loss’ of knowledge highlighted at IAEA Specialist Meeting in Bath, UK IAEA commissions AJW to prepare a proposal for debate at IWGGCR – accepted, but no funding
UK nuclear regulator recognises value for UK reactor life extension and agrees to fund the development and start-up
KNOWLEDGE BASE: A HISTORY (2) Debated at several IAEA meetings (principally with UK, Germany, USA, Japan, France, China and Russia interested) Database formally commenced in 1999 with UK handing full development and IPR to IAEA For different reasons, France and Russia do not formally participate at present: the current membership is: Germany (FZJ), Japan, Rep. Of Korea, Lithuania,
The Netherlands, The United Kingdom, The United States of America , P.R. China, Ukraine
GRAPHITE SPECIALISTS ARE NOTIT SPECIALISTS !!
Consequently, the current version of the Database usesMicrosoft Excel
Over 34,000 lines of data
Quality Assurance cannot be applied retrospectively to old data sources, but the technical steering committee reviews all source reports on the basis of its collective experience...
Rigorous QA is applied to the data-input process
FROM ‘DATABASE’ TO ‘KNOWLEDGE BASE’
Decision taken to collect the historical and current documents relating the irradiation behaviour of nuclear graphites to assist the next generation of nuclear engineers: newly-written overview documents being created at two levels – relatively simple for public consumption, and detailed technical level for project participants
Restricted Knowledge Base
Levels of access-Project members
Detailed Reports-Current technical reports-Historical scanned reports
Navigation-Context searching-Tagging-Related documents
Restricted Knowledge Base: Principal Topic Areas accessible through Individual Folders
Plus DefinitionsCodes
One stop shop for historical and current knowledge
- Incorporating the numerical database- Linking related initiatives (INGSM, CRPs etc.)
Immediate access to recent knowledge updates
- Recently acquired knowledge- Scanned historical publications
Strengthening the global community
- Relevant position on graphite research and/ or operating experience in participating member states- Enabling access to satellite knowledge bases

RECENT DEVELOPMENTS
Used as repository for CRP documents on ‘Irradiation Creep in Graphite’
Development of other sections into ‘topic folders’ BUT: had to be hosted externally with significant costs
until... IAEA introduced Sharepoint on own servers (mid-2012) Transfer effected with IAEA departmental funding for
further software development Subsequently, no hosting charges
BUT: major issues between MicroSoft SharePoint security and IAEA firewall for external users! Led to a delay of over one year in progressing the ‘population’ of the Knowledge Base
RECENT DEVELOPMENTS
Thanks to the efforts of IAEA Nuclear Energy Division and IT staff, these problems appear to have been overcome
The problem has been addressing reference documents via hyperlinks on Excel spreadsheets... Solution seems to be to replace these with direct URLs opening in a new window...
So NOW is the time to address who the users of 2015 and the future will be, and what their needs are... And that means YOU!
RECENT SUGGESTIONS
Bibliographies (UK Environment Agency proposal on i-graphite investigations being one example)
Additional reference books (subject to copyright issues)
Archive documentation from research investigations (including, but not limited to, CRPs)
Personal memoirs... ...more material waiting to be added very
shortly following a major review of the system and how it is operating (in December 2014)
GETTING THE IT RIGHT
A special meeting is being held in Vienna in December (11th-12th) with IAEA IT people to make sure we are getting the It right
This is NOT limited to the formal Technical Steering Committee (TSC) – anyone who would like to participate and can make a useful contribution is welcome to ask for an invitation
TSC will convene March 26th-27th 2015 to resume the business of populating the KB
ADDITIONAL IAEA MEMBER STATES ARE WELCOME TO JOIN THE PROJECT

committee)
