3 ITER Remote Handling Principles KEY ASPECT FOR THE SUCCESS OF A FUSION REACTOR IS TO MAINTAIN HIGH PLANT AVAILABILITY N.1 THE MAINTENANCE EQUIPMENT MUST BE RETRIEVABLE 3 Remote Handling A.Tesini PLANT AVAILABILITY RELIES ON RELIABLE COMPONENTS AND ON A STRONG MAINTENANCE STRATEGY PRINCIPLES FOR THE GOOD MAINTENANCE OF A FUSION REACTOR N.2 THE MAINTENANCE TASK MUST BE ACCOMPLISHED SAFELY & RELIABLY N.3 THE MAINTENANCE TASK MUST BE PERFORMED WITHIN SET TIME LIMITS N.4 THE MAINTENANCE EQUIPMENT COST MUST BE ACCEPTABLE

5 Blanket Remote Handling System JAPAN IVT BKT Blanket module Max 4.5 tons, exchanged via an In-Vessel Vehicle (IVT) running on a 250mm wide) x 500mm (high) passive rail deployed around the equatorial region. 5 Remote Handling A.Tesini

6 Divertor Remote Handling System EUROPE Divertor cassette 3.5m (l) x 2m (h) x 0.8m (w) weight = 8-10 tonnes. Exchange via cassette movers to lift and carry the cassette coupled with dextrous manipulators to handle tooling. Standard cassette MAM Access to the divertor region is via 3 equi-spaced maintenance ports. 6 Remote Handling A.Tesini

13 RH System Performance & Upgrade requirements Requirement n. 1: Improve in-vv RH operations performance and reliability Requirement n. 2: equipment for new in-vv RH operations (dust measurement, dust cleaning, leak detection, tritium measurement, etc.) lead to a performance and reliability assessment of the ITER RH system and to an upgrade of its current capabilities With regard to the status of the ITER baseline RH equipment capability: Scheduled maintenance RH equipment for 1. Blanket IVT 2. Divertor Movers 3. Plugs Tractors 4. Torus cryopumps equipt. to be designed 5. Hot Cell RH equipt. - to be designed Available New and unscheduled tasks RH equipment 13 Remote Handling A.Tesini 1. Current in-vv RH equipment not easily reconfigurable 2. Multipurpose, one-port access RH rescue and new end effectors deployer Not available

14 RH System Performance & Upgrade requirements 1. Execute a RH System performance and reliability assessment, both global and by sub-system 2. Based on new ITER requirement, execute a preliminary design of a RH multipurpose deployer (MPD), to be used for both in-vv rescue and new and/or unscheduled RH operations MPD main requirements: 1. Maximum payload capacity compatible with available VV access point 2. Maximum access size 3. Maximum reach MAXIMUM PAYLOAD Issue to be addressed: Storage in and deployment from existing equator port transfer cask MAXIMUM IN-VV REACH EQUATOR PORT MPD MAXIMUM ACCESS SIZE 14 Remote Handling A.Tesini

15 ITER RH Equipment Integration & Testing 1. ITER is equipped with its own Remote Handling Test Facility, i.e. the RH Test Stand. It is located inside the Hot Cell building 2. The ITER RH system will be used already from the start of the machine assembly phase (in-vv components assembly) 3. The Hot Cell and associated RH Test Stand are planned to be built and available before the start of the machine assembly phase (in-vv components assembly) 15 Remote Handling A.Tesini

17 ITER RH Equipment Integration & Testing However 1..there will be a number of commissioning and testing operations which will need to be carried out before of the delivery of the RH systems to the ITER site For example: Also 17 Remote Handling A.Tesini a. Integration of the Transfer Cask and in-cask equipment b. Re-assembly and re-commissioning of other RH equipment shipped to the ITER site from DA s outside Europe c. Integration, commissioning and testing operations on new RH systems which may be required after the RH Test Stand have become contaminated (scenario yet to be studied in details) d. Others tbc

20 ITER IO & Industry Partnership Possible approach to the cooperation between ITER and Industry 1. Creation of Industries Consortium(s) (i.e. GMES, GMEC. GIE) a. Risk sharing b. Higher probability of involvement in RH Projects 2. ITER IO on-site: Industry Consortium Front Desk a. Receive ITER instances and requests b. Discuss and elaborate contract proposals c. Coordinate and re-direct to suitable Consortium Industries 20 Remote Handling A.Tesini
