  1. CDF Decommissioning Status Jonathan Lewis Master Planning Meeting 9 November 2011

  2. Overview • PPD is implementing Phase 1 of the DOE-approved decommissioning plan • Remove all hazards related to the experimental program • Put experimental areas on display to be included in Fermilab’s educational visitor program J. Lewis--CDF Decomminssioning Plan

  3. Scope All hazards related to CDF experimental program mitigated 2nd floor, collision hall and adjacent section of Tevatron tunnel ready for tour groups of ≤49 people West high bay cleared for iARC use East high bay prepared for PPD detector development and construction lab Assembly pit prepared for joint PPD/iARC use Office areas and 1st floor counting room cleaned and ready as adjunct to PPD activities in high-bay 3rd floor computer room for CDF analysis servers J. Lewis--CDF Decomminssioning Plan

  4. 30’ Deep Pit: Cable Bridge Removed East Bay--PPD: Useful hardware recovered Workspaces readied West Bay-- IARC: Broom Clean Mezzanine Removed Counting Room Theatre Stairs to parking lot Collision Hall Access to section of Tevatron tunnel 4 J. Lewis--CDF Decomminssioning Plan

  5. Schedule October-December Secure detector Recover electronics Cleanout highbays Consolidate/remove cabinets Remove gas racks, motor-generators, etc. December Demolish mezzanines January IARC construction begins No access to west door Recover PMTs, etc. from detector J. Lewis--CDF Decomminssioning Plan

  6. Schedule, cont. • March-April • Remove cable bridge • April • IARC tie-in work on north side • Begin collision hall work • Ongoing • Counting room clean-up • Remove process systems • Life safety improvements for tours • IARC integration J. Lewis--CDF Decomminssioning Plan

  7. Status • Systems secured • No flammable gas or HV • All detector power off • Solenoid warm • Clean-up in full swing • Priority to recover of items useful to other efforts • Throwing away CDF-specific items as we encounter them • ~30 skids out the door in the past month • New lab space for mu2e • 2nd floor work room, main floor welding area • Trying to make more space soon to meet demand J. Lewis--CDF Decomminssioning Plan

  8. Mezzanine ready for demolition Gas racks gone Scrap MGs and test magnet ready for removal !st floor CR being cleared J. Lewis--CDF Decomminssioning Plan

  9. Coordination with IARC • Electrical • Freeing up experimental power substation • Moving conduit for doorway • Mechanical • Coordinating moves of sprinkler and chilled water pipes for interferences with interconnects, etc. • Mezzanine removal • Planning (Dervin Allen) • Tours for A&E, contractors, etc. • Locating utilities, electrical circuits • Reduced generator needs during utility work • Evaluating access, connections • Truck access • CDF roof access • etc. etc. etc J. Lewis--CDF Decomminssioning Plan

  10. CDF Building Improvements on D&D Budget • Main Stairwell • Remove abandoned chilled water pipes • Relocate elevator pump • 1st Floor • Remove abandoned chillers, etc. • 2nd floor • Improve exits • Isolate conference rooms and egress paths from assembly area • Collision hall • Sprinklers • Fire doors • Exit lighting J. Lewis--CDF Decomminssioning Plan

  11. Backup J. Lewis--CDF Decomminssioning Plan

  12. Plans for Display • Theatre • Place for visitors to assemble • Meet scientist? • Movie? • Trigger room • Electronics on display • Other displays? • Control room • Flashing screens look almost like we are running • Collision hall • North and west sides blown open • Plastic covers, view of COT face, etc. • South and east, closed up in running configuration J. Lewis--CDF Decomminssioning Plan

  13. Display Effort • Working with Public Affairs and Education • Making posters to document our achievements • Mix of hardware and physics • Ben Kiliminster coordinating • Interactive activities geared mostly toward middle school • Cosmic-ray test stand, etc. • CDF people: Ben Kilminster, Anna Mazzacane, JDL • Life safety improvements in tour areas • Doors, walkways • Remove obstructions • Remove halon, sprinkler mods J. Lewis--CDF Decomminssioning Plan

  14. Planned Collision Hall Layout J. Lewis--CDF Decomminssioning Plan

  15. Storage of components that may have future use Detector Items They are safe in situ Not worth labor to pull down if no use identified Phototubes, Radeka preamps, etc. Shelf Items Over the years CDF has collected lots of good stuff What you want for a detector lab (fittings, valves, connectors) We will sort to keep what is most generally useful Don’t want building to be a warehouse Plan for storage mezzanines in pit alcoves without crane coverage Sufficient space for all lockers now in high-bay J. Lewis--CDF Decomminssioning Plan
