This document provides an overview of the various remote handling procurement packages (PP) for the ITER project, with a focus on the CODAC related aspects and issues. It includes detailed information on the specific equipment and systems required for blanket remote handling, in-vessel divertor maintenance, transfer cask system, in-vessel viewing system, neutral beam RH equipment, and hot cell repair/maintenance. The current status of each package and the next steps for design, prototyping, production, and delivery are also outlined.

PP Overview23P3 – Transfer Cask System - more Transfer cask trajectories(with 500 mm safety margin around) From the picture below it can be seen that the DIV RH and TCS have to work in a coordinated way, by means of the two controllers and their supervisor Transfer cask studies have focused on trajectories studies and control system requirements; recently rescue studies on a failed cask have been completed

PP Overview23P5 – NBI Remote Handling Present scope (to be finalised) : • monorail crane serving the NB cell, equipped with specific lifting interfaces with the NB components (and compatible with DIA plugs) • source/accelerator transport cradle • MAM and tooling (including pipe tooling) • ground-based vehicle? • rescue devices? • TBD spares NB cell with monorail crane Status: • Conceptual design done • Work on interfaces and integration to be continued • PP being reviewed Crane and neutraliser Next steps (see also planning section later): • scope finalisation; design, interface finalisation (limited pre-production prototyping and testing TBD) • production preparation • production and delivery to site NB rear maintenance
PP Overview - General • Each RH system (EU is in charge of 3 and ½ of them) is a different combination of various devices (moving machinery, crane, manipulator arms, tooling, umbilical, control system) that have to work in a coordinated way by means of its own control system • To control each of these RH systems, in the RH control room the HMI (the “work-cell”) will be typically a combination of master arms, GUI with monitors showing the status of the devices (status, speed, position, pressure, safety margins, interlocks, etc.), the visual information (from on-board or fixed cameras) and from Virtual Reality (probably 3-D), and the operational instructions (sequence of elementary tasks to be performed for a given RH mission) • We (F4E) have to understand/agree the way the overall RH control system is linked with the rest of CODAC (e.g. lift, ports, corridors, etc.)

CODAC related aspects and issues - 1 • For the RH PP, IO will only issue FS (plus partial reference designs), supported by R&D where needed (see footnote, taken from former ITER Project Integration Document PID) • These FS must be complemented by the definition of a set of interface requirements: the geometrical interfaces of the components to be handled, VV ports and ducts, hot cell, building, the interfaces with the ITER CODAC, etc. (the interface takes the level of to-be-handled component, e.g. DD for the divertor) • The level of integration and consistency of the current ITER design is not yet at a stage that would allow proceeding with in-kind supplies of the EU RH PP (through the Procurement Arrangements) • Because of this, a significant effort in terms of design, finalisation of the interfaces, prototyping and testing is still required… - All RH equipment for Class 1 and 2 operations must be designed in detail prior to ITER construction. - The feasibility of Class 1 tasks shall be verified prior to ITER construction and may involve the use of mock-ups. - The feasibility of Class 2 tasks shall be verified prior to ITER construction where deemed practical and necessary and may involve the use of mock-ups. - The procedure of maintenance of Class 3 components shall be defined prior to ITER construction.
CODAC related aspects and issues - 2 • … therefore our approach is to move to the final production of the PP after prototypes are designed, built and tested, in order to identify, finalise and experimentally verify both the RH strategy and those critical interfaces which represent the essential features of the design and of components’ maintainability • another important ingredient of our RH strategy is the review and agreement with IO of the PP scope and responsibilities, because the content of the 2001 PP must be updated and completed, including CODAC interfaces • the EU RH PP consists of a variety of movers, transport casks, crane, manipulator arms, tooling, covering several functions; therefore we should move towards standardization of the design of RH devices from different PP but with similar functions: this should be driven by IO and should include the control systems • (most of) the RH PP will be used for components first installation • a new (proposed ) element of the strategy is the use of RH facilities for IO team training • a key issue is the radiation resistance of the RH components (but with dose rates spanning over four orders of magnitude!); this requires a systematic approach and a specific strategy to be elaborated

CODAC related aspects and issues - 3 • The RH procurement packages are not huge in financial terms (e.g. compared with items like the magnets) but require a lot of design and technical integration (with RAMI!), therefore we will probably have to charge the industrial suppliers with a role of “architect” • Prototyping and testing of the various RH PP in specific facilities are essential in order to (1) validate the maintenance scheme and the interfaces, (2) develop the procedures to be used straight out during 1st assembly, (3) possibly train IO team for 1st assembly • Technological items like force feedback manipulators, but not only, require a HMI already well developed since the beginning • There are time constraints for the development of the RH control system work-cells in the RH control room • Based on the points before, it is unlikely that the various RH systems will be procured “naked”, i.e. with very limited supervisory system capabilities (e.g. only control cubicle and touch screen and/or hand-held panels) • We could end up instead in having each PP delivered with its own work-cell implemented by the industrial supplier/integrator. This is exactly what is being discussed with IO RH team at the moment • This proposed approach puts issues in front of us; in particular related to CODAC are: - limit of the supply, standardisation, FAT/SAT - integration of the RH systems in the overall RH control system and in in CODAC - new developments, improvements, change of obsolete components
