ITER CODAC Plant Control Design Handbook October 2008 Anders Wallander & Luigi Scibile CHD Department
PCDH Objectives The Plant Control Design Handbook (PCDH) defines standards, specifications and interfaces applicable to ITER Plant Systems Instrumentation & Control (I&C) I&C standards are essential for ITER to Integrate all Plant Systems into one integrated control system Maintain all Plant Systems after delivery acceptance Contain cost by economy of scale (spare parts, expertise) The PCDH is applicable to all Procurement Arrangements ITER International Organization (IO) Develop Support Maintain Enforce these standards
History and Future of PCDH The development of PCDH started from the conceptual design The process to get consensus within an intercontinental group takes time The purpose of the official release IDM v.3 in July was to communicate current thinking, not to provide a contractual document Therefore the current version is conceptual We have inserted “hold-points” in the first PA The first ones elapse in April 2009 (hard deadline) Next release of PCDH IDM v.4 before April 2009 PCDH is a living document and will be released throughout the lifetime of ITER The list of standards and specifications will be extended and will evolve PCDH shall address obsolescence management
