Welcome to the ITER Project • DG presentation described the background to creation of the ITER Project – The energy dilemma – the need for large scale carbon free energy and where fusion fits in (along with renewables). – Global response from the seven ITER Members; China, EU, India, Japan, Korea, Russia, and USA (representing more than 50% of the world’s population and about 85% of the global GDP) • The technical challenges, the physical scale & the mission. – To demonstrate the scientific and technological feasibility of fusion power for peaceful purposes – ITER is the only magnetic fusion device under construction aimed to produce a burning plasma. – Input (heating) 50 MW Output 500 MW (Q=10) Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 3

Staged Approach to DT • Consensus amongst members in favor of the staged approach • Reduces project risk and more efficient for validating key systems prior to moving to the next stage • Fits better with members financial constraints • First plasma 2025 • Fusion power DT operation planned 2035 Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 4

Industrial challenges and innovation • Required manufacturing geometrical tolerances for large steel pieces weighing several tons • Superconducting power lines cooled to minus 270 degrees Celsius • Heat flux of the order 20 MW/m 2 • Largest liquid helium plant in the world • 8 year campaign to produce 200 km of superconducting cable • The ITER vacuum system will be one of the largest, most complex vacuum systems ever built: • More than 400 vacuum pumps will employ 10 different technologies. • Robotics and remote handling solutions for assembly and maintenance Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 5

Beryllium Safety • Described the role and focus of the IBMC • The need for a beryllium facility for the handling of components in compliance with the safety and security requirements. • The role of the ITER Beryllium Facilities Working Group (BFWG) set up to develop technical options, and a safe and cost effective implementation plan to meet three major milestones with respect to Beryllium activities at ITER, namely: – Deliver a Beryllium First Wall Storage, Trial Fitting and Installation Solution to be operational in December 2024. – Deliver a Beryllium First Wall Maintenance Building ready to support Pre-Fusion Power Operation PFPO-1. – Deliver a schedule for the design and construction of the facility.

DG Key messages • The project is moving forward both in site construction and in the component preparations at DA/suppliers. – A view clearly expressed and supported by DDG GS Lee during his chairing of the session. • The progress is clearly evident looking at the on site activities and time lapse photos • The project is preparing to work with beryllium • Protection of the stakeholders is an essential and top priority for the ITER Organization. • Return of experience from the Be workshop will ensure a robust and effective Beryllium Management Worker Protection Program at ITER. • The DG encouraged participants of the workshop to be advocates for the project, share their views on the progress of the project with colleagues. • The message - ITER is moving forward Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 7

Requirements from French Nuclear Safety Authority on Beryllium activities • • Key message - Safety requirements are defined by the operator, and assessed by the safety authority. The safety authority can either accepted or request revision. French Nuclear Regulations/requirements that are applicable for ITER Be activities – General ASN regulations – Specific regulations for ITER site – ITER DAC files Answer to GP actions • Regulations applicable to ITER as a nuclear facility (INB) include – The facility stack shall be designed in order to have a good atmospheric diffusion – 2 confinement systems static and dynamic are required, ventilation system provisions shall ensure a negative pressure cascade – Stationary and mobile means of atmospheric testing shall be used – beryllium atmospheric concentration and surface contamination shall be monitored – the waste disposal outlets shall be identified - Specific procedures will be put in place in order that liquid beryllium samples are not released in the industrial effluents (due to agreement with CEA) and that they are captured and transferred for a specific waste treatment. – Qualified personal protective equipment is required – There is a need for specific training prior to beryllium arriving on site • Beryllium zoning - when the zone has been identified as a beryllium-controlled zone: – access is limited only to beryllium qualified personnel, • specific medical monitoring will be associated with this beryllium-qualified personnel Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 8

Requirements from French Nuclear Safety Authority on Beryllium activities • According to RPr. S – ITER will apply safety defence-in-depth principles in order to optimize beryllium occupational exposure: – The actual beryllium release should not exceed the values estimated in the RPr. S for construction and operation • Note: values for release are higher for construction than operation; Control/confinement for operations can be easier than construction. • These values could be reconsidered assuming they can be justified • Beryllium Risk will be the major hazard during the first 10 years of ITER operations Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 9

Blanket First Wall • Key information – 2 types - NHF(2 MW/m 2) and EHF(4. 7 MW/m 2) – 440 FW panels, 12, 000 kg beryllium & 660 m 2 beryllium plasma facing surface – 4 Beryllium grades qualified for this application – Quality class 1 components 10% 40% Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization 50% Page 10

ITER Beryllium Management Committee • Beryllium is classified as a carcinogenic in France(not only). • The IBMC was formed in 2015, and led by R. Raffray with the following objectives. – – Overall supervision of the applicable legislation and regulations Identification of all activities involving beryllium Identification of best practice safety standards Prepare Incident responses procedures for onsite and offsite activities. – Implementation and coordination of the activities • Activities to date – – Coordinated the IO Be worker protection program Supported procedure for off site manufacturing follow up h Organised this Be workshop Established technical activities with support of external providers • Cleaning, smearing, audits, training, analyses, DA/supplier support… Workshop on Beryllium Applications and Health & Safety, June 30, 2017 © 2017, ITER Organization Page 11

ITER Project Associate (IPA) for Beryllium Activities • A beryllium specialist is required to support the IO for ongoing beryllium activities offsite and in readiness for delivery of beryllium components to site. • Experience in occupational hygiene and in beryllium management needed: • • to directly support the ITER Beryllium Management Committee (IBMC) activities in developing a beryllium safety program and ensuring its ongoing effectiveness to deliver the safe working environment demanded by all stakeholders; and to support the follow up of PAs on beryllium components (and in particular on the Blanket First Wall). • More details at: http: //www. iter. org/jobs/IPA (Ref. IPA/2017/023/TED) • The IPA position is for one year and renewable up to four years. • Please let us know if you know a good candidate who fits the bill. • The indicated application deadline is July 14, 2017 but the posting can be extended if a good candidate does not apply by then. • You can contact me if you are interested in obtaining more information on this.
