Transformers Requirements

02.21.18 9 David Montanari | LBNF Cryogenics Progress

From: Theresa M Shaw tshaw@fnal.gov Subject: RE: LBNF Transformers on mezzanine? Date: February 21, 2018 at 9:37 AM To: David Montanari dmontana@fnal.gov Cc: Theresa M Shaw tshaw@fnal.gov, Steve J Chappa chappa@fnal.gov, Arnab Ghosh arnabg@fnal.gov

Hi David, Our proposed DUNE Detector AC distribution is in docdb 6922. What is proposed for placement on the mezzanine are the (4) 112.5KVA transformers each paired with a Rack (4 total) which holds the Saturable Inductor and Impedance Monitor. So, similar to ProtoDUNE x 4. Each transformer: Weight ~810 lbs 30” (w) x30” (d) X37” (h) Rack: Weight ~700 lbs (guess) 24” (w) x 30 (d) x 79” (h) Note that there are also codes for working areas or “stay clear” areas around the transformers of – “The general distances for working clearance are 3 feet in front and a

minimum width of 30 inches”. Steve Chappa is thinking about the best locations for this equipment on the mezzanine, but I wanted to get you these initial numbers.

Proximity Cryogenics on Mezzanine – Highlights

02.21.18 David Montanari | LBNF Cryogenics Progress 10

  • Extended mezzanine platform by 9.6 m (Was 39.8 m, now 49.4).
  • Added two office-type spaces.
  • Increased number of controls racks (from 4 to 8).
  • Added collectors for purges in feedthroughs.
  • Added panel for GAr Analyzers to collect lines from purges.
  • Cleanup and minor modifications to pipe routing.
  • Getting requirements on transformers and racks to be places on
  • mezzanine. Will be implemented soon.

LAr Pumps – Highlights

02.21.18 David Montanari | LBNF Cryogenics Progress 16

  • Removed pump towers and replaced with inline pumps + valve

boxes.

  • Verified size of pipes and updated model. Inlet/outlet to/from LAr

pumps are now smaller:

  • 3 in SCH 10 (DN 80) process.
  • 5 in SCH 10 (DN 125) vacuum jacket.
  • Left 2.0 m x 2.0 m in NE corner for lifting device/stairs.
  • Need to add protective structure that might be 5.0-5.5 m high.
  • Working with Far Detector on Clean Room requirements and
  • interfaces. Access and space are shared in this area.
  • Working with Cryostat, Far Detector, Systems Engineering on

installation sequence.

  • Ongoing discussion on rock septum and whether it is removed.
