Pre-Hot Checkout: Timeline

• 3 Layered Approach

• Inspections (ongoing)• System Reviews (June / July / August)• Geographic Reviews (August / September)

Pre-Hot Checkout 3-Layered Approach

• Inspections– Field assessments– Identify issues– Track resolutions

• System Readiness Reviews– System status and operational limitations, checklists,

preventive maintenance plans, spare parts status . . .

• Geographic Reviews– Cross-cutting readiness– System of Systems evaluation

Layer 1 - Inspections

Evaluation of equipment readiness.

• Q/A punchlists– On-line database for tracking.

• Consistency checks between the Accelerator Song Sheets and the tunnel hardware.

– Changes routed back to Engineering for correction.

Layer 1 - Inspections - Workmanship

• Punchlist of items needing attention. April 10, 2013.

11

Layer 1 - Inspections - Workmanship

• Web based accounting.

• Operability Manager tracks to resolution.

Song Sheet Checks

Hard copies of beamline element layout taken to the field and marked up during the inspection.

Clean copy made. Engineering issues ECO and revised Song Sheets.

Layer 2 – System Readiness

14

Layer 2 - System Readiness Reviews

• System Readiness Reviews demonstrate

– System Capability• Safe & effective support for

HCO– System Readiness

• System status, spares status, maintenance plans

– Documentation• New 12GeV equipment

– Long Term Operations• Plans for 20 years of CEBAF

operations– HCO Checklists

• Status update and development plan for completing prior to HCO

• System Review results go to the Director of Operations

Layer 2 - System Readiness: ABIL

• ABIL (Accelerator Bypassed-Interlock Log) is a new system (policy, process, software) that defines the requirements for bypassing system interlocks.

• A new database was created to track bypassed interlocks.

– It replaces an outdated and under-utilized system.

• A new “Interlock Bypassed” tag was created and distributed.

– Attach one tag to the equipment for each bypassed interlock.

• Training (SAF144) is required for employees working with systems that may install interlock bypasses.

• The policy does not apply to Personal Safety System equipment.

Layer 3 – Geographic Readiness

18

Layer 3 - Geographic Reviews

• Cross cutting readiness evaluation by location

– CEBAF as a ‘System of Systems’

• Song Sheet completeness– Final field checks

• CEBAF Element Database (CED) completeness

– One for one correlation of components to the CED

• Control Screen completeness– Screens and controls available to

operate CEBAF

• Geographic Review results go to the Director of Operations

19

Geographic Reviews

• Review Committee – Broad knowledge base from Accelerator Operations,

Software, Engineering, and Accelerator Physics

– Many of the principle people involved in developing and carrying out the commissioning plan.

12GeV Construction Overview

• Work process during the Long Shutdown paralleled 6GeV era work process.

• 0800 Meetings held daily during the week

• Tools in place to guide work– Daily summaries – Work Plan of the Day (ATLis Work Map)– Long Range Plan shown daily (SAD Calendar)

• Tasks are planned, approved, documented, and communicated via the Accelerator Task List (ATLis)

23

12GeV Construction Execution

Daily reports from previous 24 hours presented by the Program Deputy during the 0800 Morning Meeting.Progress and problems are reported.Posted in an electronic logbook as a historic representation of work performed.

24

12GeV Construction Execution

ALTis Work Map provides a graphical representation of work ‘plan of the day’ and is maintained by the Program Deputy and presented at the 0800 Morning Meeting.

25

12GeV Construction Execution

The SAD Calendar (Scheduled Accelerator Down) provides a longer range look at planned work. Links to the ATLis tasks make for quick access to documentation for work including Hazard Identification, engineering documents, comments, approval, and job details.

26

12GeV Construction Execution

The Accelerator Task List (ATLis) provides a web-based work planning tool that documents safety considerations, approval process, ties to additional documentation such as permits, drawings, files, photo’s, etc.

System Readiness ReviewsC System Review Outline The following information is to be presented at the system review. The review structure is flexible, but the goal is to have at most two hours of presentations followed by one hour of constructive conversation. The review committee will be responsible for delivering a written report to the Director of Operations by the start of the HCO process (presently scheduled for 2013- Sep-16). Presentation slides and supporting documentation shall be made available to the committee two working days in advance of the review. C.1 Required Presentation Material 1. Brief overview the system status including known operational limitations 2. Demonstrate completeness of or plans to complete the 12GeV General Checkout plans (See Appendix E). 3. Operational highlights of the new or modified elements. Present any details on operational differences of the new or modified elements, when compared to the 6GeV equivalent element. 4. EHS information on the new or modified elements. Present any details of EHS differences of the new or modified elements, when compared to the 6GeV equivalent element. Include both operational and maintenance EHS information. 5. List of all completed preventative maintenance work performed during the down. 6. List of all uncompleted and/or deferred preventative maintenance work. 7. Spare parts assessment: status of inventory, prioritized list of missing spares with cost and lead time estimates. 8. Annual consumable estimate. What is the estimated annual procurement cost to keep the system

operational. 9. Present known issues with the system under review in supporting the Commissioning plan for the following run periods: HCO, AccI, AccII, AccIII, AccIV, as found at: http://opsweb.acc.jlab.org/TJ3/12GeV_CEBAF/Run Period Plans.html and achieving the milestones found at: http://opsweb.acc.jlab.org/TJ3/12GeV_CEBAF/Milestones.html. C.2 Material to be Provided 1. Hot Check Out Checklists 2. List of all new elements, compared to 6GeV CEBAF. 3. List of all modified/altered 6GeV elements.
