Overarching Commissioning Plan Ritendra Bhattacharya LCLSII Commissioning Workshop

Overarching Commissioning Plan Ritendra Bhattacharya LCLS-II Commissioning Workshop December 4 & 5, 2018

Outline • Introduction • Commissioning responsibility • Commissioning readiness • Pre-commissioning • Sequence of commissioning • Overarching schedule • Predecessor LCLS-II Commissioning Workshop, Dec 4 & 5, 2018 2

Introduction • Installation scope: Identifying activities and completion timelines in support of commissioning readiness for the cryoplant subsystems. • Pre-commissioning: Dealing with mechanical and electrical check out and system cleanups • Commissioning: Dealing with commissioning and performance of the following sub-systems ü ü Auxiliaries Helium compression 4. 5 K Cold box 2 K Cold Box • Operation: Dealing with operation of subsystems post handoff during commissioning of rest of the subsystem. Example, operation of rest of the cryoplant subsystems during commissioning of 2 K cold box. LCLS-II Commissioning Workshop, Dec 4 & 5, 2018 3

Commissioning Responsibility for Cryoplant SRR Installation Commissioning Readiness ERR Precommissioning & Commissioning Performance Test Handoff − Auxiliaries − Compressors − 4. 5 K Cold Box − 2 K Cold Box - JLAB Engineering, Pre-Commissioning & Commissioning Support - JLAB Vendor Support - SLAC Engineering, Pre-Commissioning & Commissioning Support - SLAC Installation Support SRR System Readiness Review ERR Equipment Readiness Review LCLS-II Commissioning Workshop, Dec 4 & 5, 2018 4

Cryoplant Commissioning Readiness: Installation* Completion − System Pressure Tested and Leak Tested − Loop check Continuity (up-to Terminal block) Installation Test Report − Pressure Safety System (pressure tests, relief valve/device test/check) Availability of Facility Availability of … − Electric power (Lock out/tag out) − Resources (JLabSLACVendor) − Tower Cooling Water − ODH classification and detection, alarms established − Leak tests − Circuit filled with Air or N 2 − Electrical checkout − Helium Gas contract/requisition − Cold Compressor / Turbines Cartridges installed − Control & Communication checkout − Liquid Nitrogen contract/requisition − Safety reviewed & ensured − ToolingConsumableSpares − Documentation / Procedures − Automatic valves and safety valves installed − Charcoal filling complete − Control room established − Measure to safeguard Cooccupancy of CP 2 Installation and CP 1 Commissioning. − Accessibility ensured NOTE: *including General contractor’s and reassembly contractor’s scope of work LCLS-II Commissioning Workshop, Dec 4 & 5, 2018 5

Pre-commissioning Mechanical Checkout − Piping and U-tubes properly connected with subsystem − Vent/drain connected Instrumentation and Control Checkout Electrical Checkout System Cleanup − Power is connected − Instrument calibration check − Purge/Fill cycles* − Breakers have properly rated fuses and trip set points − Valves (pneumatic & electric) functionality check − Adsorber cleanup − He filling/pressurization − Safety valves properly connected − Utility availability check − Electrical motor checkout − Instrumentation signal loop checkup − Vacuum system with cold trap connected − Control network and communication checkout − He Circulation / Flushing − Local and remote control system checkout − Alarms properly activated − Lock out/tag out complete NOTE: *Longer activity for He Gas Tanks, LN 2 Dewar cleanup and moisture removal LCLS-II Commissioning Workshop, Dec 4 & 5, 2018 6
