TRANSCRIPT
ITER is a Global CollaborationMission: to demonstrate the scientific and technological feasibility of fusion energy
Partnership: a unique collaboration of nations jointly responsible for construction, operation, and decommissioning an experimental fusion facility
Cost Sharing:
Caveat: This talk focuses on the US ITER scope
ITER is a very large project:• Will be the world’s largest Tokamak
Plasma volume = 840 m3; goal: Q = 10
Device is 30 m tall; almost a 10 story building.
• The ITER Collaboration is composed of 34 countries, representing ~50% of world population
• Total construction cost estimated at 13B€ ($17B) [source: ITER web site]
• Controls system very large, too: Est. no. computers: 1,000
Est. no. signals (wires): 100,000
Est. no. PVs: 1,000,000
• First Plasma in 2020• Deuterium-Tritium operations begin 2027
ITER Site – Cadarache, France

ITER Controls Responsibilities• In general, each collaborator (“domestic agency”) is responsible for
providing the I&C for their systems
Controls include all H/W & S/W required for system to run stand-alone (includes PLCs, fast controllers, EPICS DCS functionality, equipment protection systems, and safety systems)
“Inter-system” integration done by ITER Organization
• Project activities typically divided up so:
U.S. system “procurement authorizations” written to include design of I&C system, S/W development, H/W procurement/fab, FAT, and shipping
I&C systems begin delivery in 2015
Installation supervision and final testing responsibilities negotiated for each procurement authorization
• Collaborators tend to fill a “primary contractor” role where:
ITER Organization handles EPICS tools development
Collaborators develop EPICS-based control applications

US ITER Schedule• Project has not been base-lined by DOE yet• Here is the schedule being used for planning purposes:
ITER CODAC Team has been actively promoting standardization
• Integration will be a big challenge for the IO CODAC team
• IO has developed Plant Control Design Handbook (PCDH): Comprehensive set of standards for all aspects of control system design
• IO supplying standard demonstration cubicles to collaborators
• Collaborators must use “CODAC Core System” software developed and supported by IO
• CODAC Core System is available to the EPICS community• Deployed on NSTX at PPPL in 2010.
CODAC Architecture
ITER Component Description
CODAC Core System • The ITER standard software tool suite• Developed and maintained by ITER Organization; collaborators
must use it• CODAC Core System version 3.0 released in Feb. 2012• Currently uses EPICS base version 3.14.12.2• CSS‐based tools used for development and OPI functions
Mini‐CODAC • Used by Domestic Agencies for development and testing• Includes OPI functionality• Includes the development environment for developing IOC and
OPI applications• A temporary entity; not used for operations
Plant System Host • EPICS IOC • Typically used as gateway for PLCs, fast controllers, & COTS
hardware• Industrial PC, supplied by ITER Org. to Domestic Agencies• RHEL Linux O.S.
CODAC Plant System Components
ITER Control Component
Description
Self‐Descriptive Database (SDD) Application
• Used for much of the Plant System EPICS development: PLC table for IOC communications IOC database for PLC communications A basic CSS BOY screen (list of PVs with status) CSS BEAST alarm configuration CSS BEAUTY archiver configuration
• Runs on Mini‐CODAC
Slow Controller • Siemens Simatic S7 PLC series
Fast Controller • Used for fast control applications (when >100 Hz response req’d)• Industrial PC serves as CPU• RHEL MRG real time linux O.S.• Includes embedded EPICS IOC for interface to CODAC• PXIe chassis houses I/O• National Instruments is the primary supplier of I/O modules
CODAC Plant System Components
ITER Control Component
Description
Other COTS equipment?
• May be a need to use other COTS control equipment for some specialized applications
• Will need to be negotiated with IO
Plant Interlock System Controller
• Used for equipment protection• Architecture is dependent on time response required:
Either a high‐availability Siemens S7 PLC system Or a TBD fast controller architecture
Plant Safety System Controller or Logic Solver
• Used for personnel safety or nuclear safety instrumentedsystems
• Architecture is dependent on integrity requirements: Either a high‐availability Siemens S7 PLC system Or a TBD high‐integrity logic solver
CODAC Plant System Components
US ITER Controls Organization• U.S. effort is also a collaboration
ORNL, PPPL, SRNL, other
• Project office located in Oak Ridge• U.S. system responsibility ends after equipment
delivery or commissioning at ITER No operating facility left in U.S. when it’s over
• Consequently much of the controls work will be subcontracted vs. hiring dedicated national lab employees
Subcontracted work to include PLC, EPICS, fast controller, equipment protection, and safety system applications
• I&C managed at “3rd level WBS” No centralized controls WBS
US ITER Controls Progress• US CODAC Working Group formed
Interpret and support ITER CODAC standards among US participants
Includes representatives from each major system
Includes representatives from ORNL, PPPL, and SRNL
• Hired controls integration person at USIPO
• TCWS (including I&C) Preliminary Design Review held Action item resolution in progress
• ECH Transmission Line Preliminary Design Review held Action item resolution in progress
• Other systems still at conceptual or preliminary design stage
• Set-up of test stands using CODAC in progress
• Negotiations in progress with SNS to provide technical support
US ITER Controls Next Steps
• Continue I&C design efforts Short-term, mainly TCWS and ECH/ICH transmission lines
CODAC Working Group to develop CODAC-support.
• Get through DOE CD-2 Review!• Complete set-up of test stands
For Pellet Injector, ECH/ICH transmission lines
• Set up demonstration cubicle Built by IO to support U.S.
Shipment in progress
• Search for qualified subcontractors for I&C design , software development , and control rack production to ITER Specs
