Purpose of this presentation:

• To show that the proposed LBNF system design will closely

mimic the design and subsequent upgrades of the system currently in use in NuMI for nearly a decade

• To highlight the major changes from NuMI to LBNF
• To address any safety, serviceability issues before completion of

Prelim Design and the Design Review at the start of the year

What is desired from the stakeholders & project management:

• Do you see any show-stoppers not already addressed by either

NuMI or LBNF?

• Are we at a sufficient level of design, incorporating operational

and safety concerns, to proceed with the goal of Preliminary Design Review about the start of the new year? NOTE: A full Preliminary Design Review of this system will occur with all

• ther TH RAW Systems, about the start of the new year

Status: The RAW Exchange System is approximately 60% through the Preliminary Design Stage

• P&ID, Modeling virtually complete
• Design incorporates many lessons learned from NuMI, as well

as significant input from the current NuMI systems engineer, Dez Deshpande

• Civil (NSCF) as well as all stakeholders involved with the

components have been involved with LBNF RAW Room and corresponding RAW Systems design thus far

NuMI system items kept:

• Two modes for drain and fill maintained:
• System off requiring full drain and make-up
• on-the-fly ability to burp and make up a small quantity of RAW from

any particular system during operations

• Containment
• Tank still vents to a safe path for tritiated air to escape though

the TH complex

NuMI system items kept, cont.:

• Redundant valves in the same locations
• Transfer station and controls located outside of RAW Room for

access during beam operation

• Transfer controls in a local station, with identical safety lockout,

requiring RSO or designee to be present for operation

• Piping run overhead to maintain clear aisles

Modifications:

• NuMI services 3 RAW systems: target + 2 horns
• LBNF will service 5 RAW systems: target + 3 horns + shielding
• NuMI uses extraction line LCW + house chilled water systems

for intermediate systems, not serviced by the Exchange System

• LBNF will use a dedicated intermediate system, serviced by the

TH Exchange System, in a similar fashion to the NuMI Absorber Hall intermediate system in use

• Both RAW capture and LCW make-up tanks have increased

volume to service 2 more RAW systems and greater volumes

• Sufficient capture volume to ensure prolonged running between

services (raised from 300 to 1200 gallons)

• Increased LCW fill tank, from 30 gallons to 200 gallons
