D&D Task Force

22 November 2011

J. Lewis--CDF Decomminssioning Status2

Schedule (Review)

• 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

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


Status

• Systems secured No refrigerants, 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



Gas racks gone

Scrap

Mezzanine ready

for demolition

MGs and test magnet

ready for removal

1st floor CR being cleared

Status 11/8

Status Today


Schedule Status

• Mostly on schedule West bay nearly done Mezzanine demolition delayed to January to

accommodate IARC ground breaking Need west door truck access.

East bay work rearranged Ahead on gas systems Behind on cabinet clean out More control system work than anticipated

First floor counting room pushed earlier to make equipment recovery easier

More equipment recovery work than planned Collaborators showed up at the end of the run

with requests and demands


Issues

• Proposed experiments create significant uncertainty for D&D Protoplasma ORKA

• Cable bridge plan assumed 20-year display phase Removing bridge before detector makes detector

removal trickier• If CDF is to be rolled out in the next few years, we

should defer cable bridge removal until then Work is on hold pending guidance from the Director

• If CDF will be dismantled for experiments, how far do we go with the display plan Dismount plug?


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


CY2012 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


Backup


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



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


Counting Room Theatre

Stairs to parking lot

West Bay-- IARC:

Broom Clean

Mezzanine Removed

30’ Deep Pit:

Cable Bridge

Removed

East Bay--PPD:

Useful hardware recovered

Workspaces readied

Collision

Hall

Access to section

of Tevatron tunnel

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


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



Planned Collision Hall Layout


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

Alcove Plan
