LBNF

Overview

• Many, major activities occurring at SURF over next ~15 years- Operations and decommissioning of LUX- Assembly, operations, and decommissioning of MJD- Installation and operations of CASPAR- Installation and operations of the BHSU UG Campus and LBCs- Completion of Ross Shaft refurbishment and continued SURF Ops- Construction, installation, and start of ops for LBNF/DUNE- Installation and operations of LZ

LBNF

Logistics Plan Scope


• Arup developing comprehensive logistics plan out to ~2030- Construction and installation plans including utilization of SURF and

surrounding infrastructure, number and timing of deliveries, hours of required operation, parking, and warehouse and lay down space needs.

- Plans for waste storage and removal from SURF.- Traffic management including loading, unloading, parking, planned

access routes, capacity and utilization for transportation of materials, supplies, equipment, and staff.

- Recommendations on facility infrastructure modifications or process changes to improve the efficiency of all activities.

- Summary of risks specifically related to logistics plans.- Projection of personnel involved onsite throughout construction and

installation and recommendations on staff support including housing- Site security and safety considerations.

LBNF

Topics covered


• Infrastructure overview

• Surface and underground tours

• Presentations by SURF operations, LUX/LZ, Majorana, CASPAR, BHSU Underground Campus (low background counting)

• LBNF/DUNE presentations by CF, cryostat, cryogenic systems, FD

• Risk identification / analysis of items related to logistics

• Arup led discussion of the topics outlined in the logistics scope

• Presentation of information captured in excel-based toolset to track SURF infrastructure usage over time

LBNF

Key items reviewed in evaluating infrastructure usage


• Each group provided a detailed presentation on schedule and infrastructure needs and a resource usage spreadsheet

• Key constraints- Shaft access- Big X- Governor’s Corner

• Shaft options for LBNF+DUNE- Ross only- Ross + Yates “as-is”- Ross + Yates “upgraded” (assume not feasible for now)

• We looked at Ross Shaft for ALL work on LBNF+DUNE only

LBNF

Planning outputs - Assumes Ross Shaft only for LBNF/DUNE (draft)


LBNF

Draft schedule and Ross Shaft utilization(Excavation, BSI, and Cryostat phasing needs to be addressed)

Top 15 risks identified – pre-mitigation scoring


ENGR-268

SciencePre-Blast Analysis

If pre-blast analyses are not conducted for experiment structures, then unanticipated damages will result.

Threat

ScienceYates Shaft Brow Work

If the Yates shaft brow work goes ahead, then there will be delays and impacts to multiple science experiments.

ENGR-260

ScienceIntegration Failure

If there are science experiment requirements that are not clearly defined, then there will be integration failures.

ENGR-296

GlobalSafety Incident

If there is a significant injury or safety incident, then there may be a work stoppage (safety stand-down and/or investigation).

Threat

ENGR-286

ShaftShaft Availability

If Ross and Yates Shaft availability were better understood by project team, then the use of the shafts could be better planned more efficiently.

Opportunity

4-Likely-51-80%

2- $1M - 3M2- 1 to 6 months

ENGR-278

Shaft Hoist ControlsIf drives and controls and hoists are not modernized, then continued safe and efficient operation cannot be guaranteed.

Threat

3- $4 -10M2- 1 to 6 months

ENGR-253

SurfaceSurface Laydown

If there is insufficient laydown space at Yates and Ross surface areas, then experiments and contractors will need to seek offsite storage.

Threat


1- Less than $1M

2- 1 to 6 months

8

ENGR-254

SurfaceSurface Facilities

If there is a shortage of surface warehouse space, dry space, and storage capabilities, then this will impact the project.

Threat


1- Less than $1M

2- 1 to 6 months

8

ENGR-256

ShaftShift Schedules

If assumed shift schedules for each portion of project aren't aligned, then there will be confusion and other issues.

Threat


1- Less than $1M

2- 1 to 6 months

ENGR-274

ShaftYates Shaft Availability

If current Yates Shaft availability cannot be increased, then all experiments may impose more demand on the Ross Shaft, delaying all operations.

Threat

ENGR-277

ShaftAdditional Experiments

If new experiments (e.g. rock-melting or rock-fracturing) are added during project construction, then there will be additional burdens on access, shafts, and other resources.

Threat


1- Less than $1M

2- 1 to 6 months

ENGR-289

BSIBlasting Schedule

If blasting takes place while people are underground, then safety issues may arise if QC is not very high..

Threat

3- 6 months to 1 year

ENGR-258

SurfaceSurface Compressor Footprint

If surface nitrogen compressors don't require a building (e.g. by using an enclosure or other means to minimize the footprint), then laydown space may be freed up.

ScienceManpower Levels

If maximum manpower levels underground are not coordinated during science operation and construction, then priorities will need to be adjusted and delays may be incurred.

LBNF

Mitigations to be considered


• Install concrete slick line borehole from surface to 4850L to remove concrete/shotcrete transport from the Ross Shaft

• Install boreholes for nitrogen and argon gas delivery to 4850L

• Assuming LBNF/DUNE utilize Ross Shaft for transport of long loads (up to 17m), modify Ross Headframe accordingly and/or evaluate shortening of cryostat steel beams to ease installation

• Utilize Yates Shaft as is – do not modify for long loads and avoid impacts to Davis Campus experiments

• Plan and conduct controlled blasting test program to evaluate impacts for LBNF excavation on other 4850L inhabitants

• Evaluate acceleration of phase 1 excavation to speed cryostat 1 installation and thus FD installation. Adjust EXC, BSI, and cryostat schedules to fix phasing of CF to cryostat installation
