LBNF Shaft Scope Utilities in the shaft include: Power Fiberoptics for data separate from fire alarm Cellular leaky feeder Nitrogen (three 12”, two 8”) and argon (one 8”) gas pipes Concrete slick line for construction in 6 winze Fire water pipe from 4100L to 4850L Existing 4” water line will feed a sump at the 4100L and continue past to service other water needs. 6” fire line from 4100L sump to 4850L Other shaft scope (early work managed by SURF): Ross rehab continues through mid New cage and skips Joshua Willhite | FSCF Scope8 Changing for 100% (2) 16” N2 pipes rather than (3) 12”
LBNF Yates Shaft Scope For the 100% preliminary design, Arup is including the following work for the Yates Shaft: Removal of bracing in the headframe to accommodate 17m long beams Replacement of timber within shaft from just above the 4850L to the bottom with steel Raising the brow at Yates to accommodate 17m long beams Enlarging the 4850L station to allow beams to come out of skip compartment Joshua Willhite | FSCF Scope9

LBNF Waste Hauling Joshua Willhite | FSCF Scope20 All LBNF CF Deliveries (explosives, ground support, MEP, etc.) will be delivered through the Ross shaft. Depending on phase and work location, these may go past Governor’s corner, through the trolley drift, or through the waste rock drift. Ross Campus access vary change as excavation progresses.

LBNF Controlling Impacts to other Facilities The Ross Campus is fairly close - ~100m from the nearest extent of the campus to the nearest excavation. The Davis Campus is ~1 km upwind of LBNF, so controlling impacts to this campus during most of the construction is relatively straightforward. The addition of raising the Yates shaft brow imposes new concerns at Davis. “The anticipated blast vibrations at the Davis Campus are anticipated to be less than 0.03 in/sec for typical controlled blasting techniques using up to 20 pounds of explosives per delay. This is approximately equal to the threshold of perception of motion indicating that blast vibrations will likely not be detectable by laboratory personnel at the Davis Campus.” CF has proposed a limit of 0.5 in/sec vibration and 134 dBL air blast overpressure, both derived from standard mining criteria. Vibration is controlled with explosives load size and distance, air blast is controlled with isolation walls and doors Joshua Willhite | FSCF Scope23
LBNF Vibration Control (load size vs. vibration) Joshua Willhite | FSCF Scope24
LBNF Air Blast Control Most extreme situation is when building a cryostat in cavern 1 while blasting the second pit due to proximity and cross section – draft concept shown at right (under development) Control at Ross Campus is most challenged by retaining ventilation Joshua Willhite | FSCF Scope25
LBNF Life Safety Life safety analysis has defined compartmentation layouts and fire rated egress pathways in each phase. Note that ODH analysis and control is the responsibility of the cryo group, who have defined minimum air flow. Compartmentation for fire events also provides for ODH, but is not designed specifically for it. The existing refuge chamber is currently outfitted for 72 persons, 96 hours occupancy. One SURF Operations project is planning to upgrade this room to support as much as 150 occupants. This study will help determine whether this is adequate Joshua Willhite | FSCF Scope26

LBNF Plumbing and Fire Suppression Cryogenic gas pipes come through the shaft and are taken to the central utility chamber – No liquid cryogens outside of the LBNF footprint. Water is only required for the HVAC system (spray chamber makeup, cooling) and fire protection. Both will use industrial water supply. New supply will tie in with supply being installed for CASPAR and BHUC (derived from David supply), providing redundancy for all campuses. Potable water is provided via UV treatment (identical to Davis and Ross Campus systems) for miscellaneous us. Fire suppression systems (sprinklers) are provided in all areas (except mucking ramp) created for LBNF. Pre-action type in detector caverns. Wet in drifts Joshua Willhite | FSCF Scope31

LBNF Controlling EMI To control electrical interference between facility and experiment electronics, separate shielded transformers are provided, and the experiment ground is isolated using inductors and insulators. Additional requirements have been stipulated to avoid ground paths through detector caverns and provide minimum cable lengths to dampen EMI frequencies Joshua Willhite | FSCF Scope34
LBNF Fire Detection Fire detection monitoring will include Smoke detection (VESDA) Oxygen concentration monitors CO detection Heat detection Sprinkler water flow switches Manual pull stations Notification will include alarm, voice, and visual (strobe) Control panels will be strategically located at the 4850L, as well as within the surface control room. System will be coordinated with existing Ross and Davis Joshua Willhite | FSCF Scope35
