Transformers Requirements 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. -Terri 9 02.21.18 David Montanari | LBNF Cryogenics Progress LBNF

Proximity Cryogenics on Mezzanine – Highlights • 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. 10 02.21.18 David Montanari | LBNF Cryogenics Progress LBNF

NP-04 – Protection for Protego + Valve Box 15 02.21.18 David Montanari | LBNF Cryogenics Progress LBNF

LAr Pumps – Highlights • 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. 16 02.21.18 David Montanari | LBNF Cryogenics Progress LBNF
