1. 27/10/2008 - JW Farthing 1 Barcelona, 27 th, 28 th October 2008 Jonathan Farthing jonathan.farthing@jet.uk CODAS & IT Department, UKAEA Culham Questions and Answers Session F4E Colloquium on ITER-CODAC Plant Control Design Handbook (PCDH) and EU Procurement of Control and Instrumentation for ITER jonathan.farthing@jet.uk

2. 27/10/2008 - JW Farthing 2 F4E PCDH Remote Review 2008 PCDH V3 was distributed with the details of this meeting –Asking for comments / questions about PCDH and more general ITER-CODAC and I&C –Detailed responses will be published and passed on to ITER-IO Layout of the document to improve clarity Safety Systems Human Factors Suggestions about inclusion of other standards Some general comments and questions follow –To promote discussion now and in the parallel sessions

3. 27/10/2008 - JW Farthing 3 Questions - 1 F4E –Do the centres of excellence proposed by ITER-IO make sense? –What is the best way to do it? –Timescales to set up? ITER –How will they work? Parallel sessions?

4. 27/10/2008 - JW Farthing 4 Questions – 2 PCDH There are a large number of TBD’s in PCDH V3 –What are the plans for a more complete version? F4E –When does the first F4E plant system require the complete PCDH – contractually or technically? –What can F4E do to help flesh out the TBD’s? –Parallel sessions?

5. 27/10/2008 - JW Farthing 5 Questions – 3 Standardisation PCDH V3. “Final choices between competing candidate technologies are still outstanding” –When will the selection of technologies be complete? –The first plasma is planned for 2018. Is it a mistake to select the technologies so early? –Will it be possible to integrate new technologies? –What will be the process by which ITER-IO checks the I&C in the plant systems – for non-conformities? –How different will physics diagnostics be from more industrial- like plant systems? How many “special cases” will there be? –Parallel sessions?

6. 27/10/2008 - JW Farthing 6 Questions - 4 For Industry Do you agree with the strategy of the PCDH and standardisation for Plant System I&C? –How many bids will there be for non-conformities against the prescribed technologies? When it has been fleshed out will you be able to use the PCDH to build I&C for the plant systems? What is missing altogether? Parallel sessions?

7. 27/10/2008 - JW Farthing 7 Questions - 5 Obsolescence Management “Considering the life cycle of the Project (35 years) and the life cycle of the I&C components a specific chapter should cover the strategy to adopt in case of obsolescence. Either by storage or by successive evolutions” –IEC 62402 –Should there be a separate chapter on obsolescence? –Do we over-emphasise this problem? Parallel sessions?

8. 27/10/2008 - JW Farthing 8 Questions - 6 Plant system self-description –Referred to throughout the PCDH –Can it work? –Is it too ambitious? –Are there similar examples already adopted in industry or elsewhere? –Parallel sessions?

9. 27/10/2008 - JW Farthing 9 Questions – 7 ITER-CODAC What are the timescales for the procurement of the high-level ITER-CODAC systems? –Is there a procurement plan? –When will the hardware selection take place? –Commercial or Open Source software? –Parallel sessions? Any comments about the Plant System Host and mini-CODAC or other parts of ITER-CODAC? Parallel sessions?

10. 27/10/2008 - JW Farthing 10 Questions – 8 CODAC, Interlocks, Safety –What will be the mix between these three tiers? –How will decisions be made for each plant system? –How will interlocks between plant systems delivered by different DA’s be handled? –Parallel sessions?

11. 27/10/2008 - JW Farthing 11 Questions – 9 The PCDH references several other documents –RD1: Project Requirements, RD2: Plant Description Document, RD5: Electrical Design Handbook, RD9: ITER Quality Assurance Program, GD1: CODAC Conceptual Design Document etc –How to get access to these documents? –Does F4E need to make them available to all EU interested parties or will ITER give ~public access?
