ESS Project Roles • ESS Project Manager (PM) Role: Assist the DG and work with Directors and Sub-Project Leaders to deliver the ESS Construction Project according to its baseline approved scope, schedule, and cost • Responsibility and authority, and therefore accountability, to successfully complete the sub-projects remains with the existing project and line organization • PM and Technical Coordinators, as part of the DG office, are accountable for the entire project and are focused on interface management and resolving issues/eliminating impediments to progress 4

Integration responsibilities • Integration of In-Kind Contribution (IKC) partners with the overall ESS project is the responsibility of the sub-projects – Typically it is the primary job of our Work Package Managers • For the Target’s Beam Extraction System and NSS’s Shielding Bunker, ESS-Lund is self-performing the work – But, both of these systems have important interfaces with IKC partner systems and the buildings and site infrastructure • For example, these systems interface with individual instruments (many IKC partners) and several Target systems such as the Monolith Vessel System (ESSBilbao) and Moderator and Reflector System (FZJ) • Interfaces between beamlines is the responsibility of NSS • Integration across sub-projects is the responsibility of the ESS sub-project leads, e, g. Target-NSS-CF • One of the primary responsibilities of the PM and Technical Coordinators is to help with these integration processes 5

Integration processes at ESS • Interface agreements between systems are documented in Interface Control Documents (ICDs) – Sub-project to sub-project ICDs are the responsibility of the Sub-Project Leaders – ICDs between systems are the responsibility of the Work Package Managers • ICDs are required to be in place at the Preliminary Design Review (PDR) stage • Interface requirements and how they are satisfied is an explicit part of the PDR process • This is difficult to manage for interfaces between systems at very different stages of maturity • ICDs serve as a way to document the results of a negotiation process, and having it as a requirement before proceeding to detailed design often drives the discussion to a meaningful and timely conclusion – Also serves a communication function once it is established • Integration is also aided by the Machine Directorate’s Systems Engineering Group and the Engineering and Integration Support Division – Requirements development processes – Spatial conflicts in integrated CAD model 6

Stability of design • Conventional construction is underway for many parts of the facility or in detailed design for the rest (target building and instrument halls) • Most accelerator and target systems are in final design (or beyond) • Most NSS systems are in the preliminary design stage (bunker and instruments) • PDR for Beam Extraction System within the Target Monolith was held recently – Target-NSS ICD revised following the review – Still opportunities to improve before final design completion, but there is a strong sense of urgency to lock things down • Bunker PDR is planned for Dec 2016, Critical (final) Design Review (CDR) April 2017 – Closing in on final concept, but alternatives are still to be considered – Understanding and addressing interface requirements and finalizing the concept must be achieved soon 7

Other Considerations • Design review panels include representatives from interfacing systems – For example, representatives from Remote Handling Systems and NSS participated as panel members for the recent PDR for Target’s Beam Extraction System • Operation and maintenance considerations must be factored into requirements and design concepts established at the PDR and incorporated into the final design – In general, the people leading the efforts during the design phase will “own” the systems in operations, which helps to ensure that operational aspects are included 8

Urgency • Installation of the beam extraction systems and bunker are on the critical path to our Beam-on-Target milestone • There is adequate time for completing design and procurement steps, but only if we move forward expeditiously 9
