Bunker Critical Design Review Welcome Charge Shane Kennedy

Bunker Critical Design Review Welcome & Charge Shane Kennedy NSS Project Leader www. europeanspallationsource. se Bunker CDR#2, Medicon Village, 15 th October 2018

NSS Project scope: 15 neutron instruments + test beamline + support labs + NMX D 08 + BEER C-SPEC BIFROST E 04 MIRACLES MAGIC ODIN T-REX DREAM D 07 E 03 Nuclear Physics Institute HEIMDAL Test Beam Line VESPA SKADI + ESS Instrument Layout (September 2017) FREIA LOKI ESTIA D 04 ESS Lead Partners for instrument construction ESS In-Kind Partners also collaborate on sample environment, data management, lab fitout (D 04, D 08, E 03 & E 04) etc.

Recent history (CDR#1 -. CDR#2) • Main changes needed after CDR#1 (i. e. Requirements, neutronics, documentation) Ø Zvonko will discuss • ESS Rebaselining: • BOT shift from Oct 2019 to July 2022 • consequences for bunker 3

Charge for this review meeting Purpose: to assess whether bunker design satisfies all stated design requirements and whether it is defined at a level of detail consistent with release for engineering detailing and manufacturing, according to the procurement/production plan for the project: Specific questions: 1. Are system requirements and interface requirements properly defined and complete? 2. Have safety and hazards been properly considered and addressed? 3. Do the System Design Description documents and related drawings adequately describe the design to the degree needed for fabrication or procurement; as per the project plan? 4. Does the design satisfy the functional and performance requirements? 5. Are the Manufacturing Plan, the Installation Plan, and System Analysis Reports finalized and do they support the stated design? 6
