Note that design alterations resulting from the results of the MB-ECCTD are not ruled out by this requirement. R/QThe R/Q of the cavities designed for the MBL cryomodules shall not differ from that of the ECCTD cavity by more than +/-3.5% R/Q should be calculated at a beam velocity of beta = Note that no alteration of the geometric beta of the cavity is suggested by the use of this value for beta. Epeak/EaccThe ratio of the peak surface electrical field (Epeak) to the accelerating gradient (Eacc) for the cavities installed in the MBL cryomodules shall not exceed that of the ECCTD cavities Eacc should be calculated for a beam velocity of beta = Note that no alteration of the geometric beta of the cavity is suggested by the use of this value for beta.

PDR - Definition “Preliminary Design Review(s) reviews preliminary design, sometimes referred to as conceptual design. A PDR assesses preliminary design options and decisions in comparison with ESS input baseline reference design including requirements. A successful PDR demonstrates that design is sufficiently developed, clear and agreed between ESS and the Partner. Preliminary design updates the baseline reference design which was agreed at Kick-off, and a successful PDR establishes a new baseline, described in [CMP] The ‘Allocated Baseline’ from which the Partner may proceed to detailed design, including any agreed pre-series prototyping. For planning purposes, a PDR should be limited to no more than one working day.” 20

PDR - Deliverables The contents of the technical data package for PDR(s) shall include but not be limited to: Requirements, agreed or proposed updates to documents comprising the baseline reference design. Design Reports, including reports of prototyping and other preliminary design-related analyses, tests, simulations. Design Data, (preliminary design level of detail) including 3D CAD models and CAD drawings, general arrangement drawings, P&ID, FE models, etc., and interface descriptions including at least interface identification and any preliminary design definition. RAMI Report, an initial version of a report of the estimation of the probability and consequences of failures in equipment as well as main maintenance tasks and proposed spare parts. Safety Report, an initial version of the safety risk assessment report (including identifying hazards and evaluating likelihood of incidents occurring and severity of potential consequences, also list of existing control measures). [PQP], any outline draft for the Project Quality Plan including initial identification of Standards to be applied, initial planning for compliance testing and inspection, and initial planning for verification. 21

CDR - Definition “Critical Design Review(s) conclude Stage 1. The CDR assesses if the design meets all facility element requirements with acceptable risk and within the cost and schedule constraints. The CDR demonstrates that the maturity of the design is appropriate to support proceeding with full-scale fabrication, assembly, integration, test, and future operation and decommissioning. The CDR should also review initial planning for verification. Detailed design updates the baseline reference design which was agreed at Kick-off, and any ‘Allocated Baseline’ of preliminary design established by PDR. A successful CDR establishes a new baseline, described in [CMP] as the ‘Design Baseline’ from which the Partner may proceed to Stage 2 Realisation and Verification. “ 22

CDR “The contents of the technical data package for CDR(s) shall include but not be limited to: Requirements, agreed or proposed updates to documents comprising the baseline reference design. Design Reports, including reports of prototyping and other design-related analyses, tests, simulations. Design Data, (detailed design level) including 3D CAD models and CAD drawings, general arrangement drawings, P&ID, FE models, etc., and detailed interface descriptions including interface identification and definition for controlling interface design. RAMI Report, a report of the estimation of the probability and consequences of failures in equipment as well as main maintenance tasks and proposed spare parts. Safety Report, safety risk assessment report (including identifying hazards and evaluating likelihood of incidents occurring and severity of potential consequences, also list of existing control measures). Verification Plan, (including planned FAT and SAT activities) [PQP], a full draft for the Project Quality Plan including identification of Standards applied in design, procurement, manufacture and assembly, and planning for compliance testing and inspection.” 23

CDR “The CDR data package shall also contain documentation to initiate a competitive tender for the procurement of the facility element and to support the project activities. The CDR data package should additionally include but not necessarily be limited to: Procurement Package, a complete documentation package for the procurement of the facility element including as a minimum a statement of work, manufacturing follow-up description, applicable and reference documentation Project Plan, updated plan in Gant chart form, describing in detail remaining Stage 1 activities, describing in detail Stage 2 Realisation & Verification activities, and an outline of any Stage 3 Installation, Commissioning and Initial Operations activities for the Partner. Risks, Risk Register, showing identified project management risks and/or technical risks.” 24

Example of status/doc at CDR-phase To start stage 2 the necessary prerequisite are the following: The interface document of the cryomodules with the tests stations at CEA Saclay, with the transport to ESS-Lund, with the test stand at ESS-Lund and with the LINAC infrastructure is settled by the end of stage 1. The acceptance criteria for the cryomodule assembly are settled by the end of stage 1. The ESS acceptance management process is operational. The verification plan followed up all along the cryomodule assembly, at the test stand at Saclay until the shipment to ESS-Lund is settled by the end of stage 1. The configuration items for cryomodule is clearly defined. The cavity string configuration with individual cavity performance for each cryomodule is known 3 weeks before the assembly. The last version of all assembly drawings and P&ID is released at the end of stage 1. Each design change needs an acceptance from CEA and the assembly drawing has to be updated and released to CEA. The ESS change management process is operational. The ESS-“CHESS” interface is operational to upload the cryomodule assembly documentation. The ESS non-conformity management process is operational. Transport test is successfully performed. Could this sentence be more specific? Should we clearly refer to a “document management database”? 25

Charge to the Committee This review constitutes the principal technical and project review of the Work Package for this year. Additional specific design reviews may also be held. Keeping in mind the current status of the Accelerator Project, the committee is asked to review the information presented, answer to the extent possible the questions below and make specific recommendations to increase the likelihood of success of the Work Package. The result of the review will be a short report that includes recommendations. The committee serves in an advisory capacity to the Work Package Leader and the ACCSYS management team. Has the work package reached a level of technical maturity consistent with its current status on the schedule? Are there any technical concerns regarding the work package? Is any additional development or testing required for the work package to meet its goals? Are the requirements for the work package well understood and documented? Are all the interfaces between the work packages and other work packages and products properly defined, understood and agreed upon? Have all safety issues in the work package been properly identified and dealt with? Are there sufficient resources (funding, staff) assigned to the work package to allow the goals of the work package to be met? Are there decisions that need to be made in order to allow the work package to meet scope, cost and schedule? Are there any outstanding procurements or personnel actions that are limiting the progress on the Work Package? Is the Work Package on track to meeting its milestones? Are there any adjustments to the schedule and milestones that should be made? Are there any changes to the work package scope that should be made?
