1. INTRODUCTION

UT-Battelle, LLC, herein referred to as the COMPANY, is the Management & Operations contractor for the Oak Ridge National Laboratory located in Oak Ridge, TN, under the U.S.

Department of Energy (DOE) Prime Contract No. DE-AC05-00OR22725. To support the laboratory’s mission, a bulk liquid nitrogen system (LN2) is required to support a test facility at the Oak Ridge National Laboratory (ORNL). The system will supply high-pressure gaseous nitrogen and low-pressure liquid nitrogen to the facility for various utility functions.

2. SCOPE

The awarded supplier, herein referred to as SELLER, shall be awarded a Purchase Order to complete the full scope outlined in this statement of work for UT-Battelle, LLC. on behalf of Oak Ridge National Laboratory (ORNL), herein referred to as the COMPANY. Once the design is approved, the SELLER shall design, fabricate, and deliver the system.

This statement of work defines SELLER and COMPANY responsibilities for the design, fabrication, and shipment of a LN2 bulk delivery system for delivery in both the gaseous and liquid phases, including the skid-mounted LN2 storage tank, vaporization equipment for gaseous use, pressure reducing phase separator for liquid use, vacuum-insulated LN2 delivery piping, and any other designed components to provide specified functionality.

3. BULK STORAGE TANK DESIGN

SELLER shall design and fabricate a LN2 and N2 gas delivery system to satisfy the following requirements:

• Capacity: 2000 Liters (for gas and liquid use)

• System Layout: See ATTACHMENT C (Section 10)

• Gas operating pressure: 150 PSIG nominal

• Final gaseous line pressure regulator

• Gas delivery rate: 3500 SCFH maximum

• Vaporization System capable of providing the required gas delivery rate

• Pressure Building System

• Liquid supply pressure 22-25 PSIG

• Liquid use flow: 3 GPM nominal

• Vacuum Insulated Piping (VIP) connections for liquid use valve

• Pressure reducing phase separator for liquid use

• Standard level and pressure measurement instrumentation

• Pressure and thermal relief valves as needed per design

• Back pressure regulator for tank venting during low demand periods

• Tank will be located outside of the laboratory space and must be able to withstand seasonal elements while maintaining functionality.

SELLER shall ensure the tank meets ASME BPVC Section VIII, Div. 1 requirements.

SELLER shall provide detailed engineering drawings outlined in Section 8 Deliverables.

4. SYSTEM PIPING DESIGN

SELLER shall design a vacuum insulated piping (VIP) system to deliver LN2 in the liquid phase.

The piping system shall meet the following requirements:

• Transport LN2 to the facility as shown in Attachment C. Pipe routing alternatives may be submitted for BUYER approval.

• Recommended pipe support types/locations to be provided by SELLER.

• Include a heated, high point vent to release any trapped gases in the delivery system

• Deliver LN2 to a filling station, featuring a flex hose and phase separator

• Include a remote, pneumatically actuated fail-closed emergency shutoff valve.

All piping shall meet ASME B31.3 Process Piping code as applicable.

Piping design should be submitted to the TPO via email, along with other requirements stated in the Purchase Order. TPO to review and provide acceptance in writing within 30 days, prior to commencement of fabrication and material purchasing.

5. SYSTEM FABRICATION, PACKAGING AND SHIPMENT

Delivery of assembly to Oak Ridge National Laboratory in Oak Ridge, Tennessee:

ATTN: Technical Project Officer (TPO) or Equivalent

Oak Ridge National Laboratory

1 Bethel Valley Road

Oak Ridge, TN 37830

The SELLER shall submit a packaging and shipping plan to the TPO for approval before shipment. The packaging and shipping plan shall meet or exceed the following requirements:

SELLER is responsible for cleaning tank and piping systems, capping all piping connections, sealing, securing, and shipping the assembly. Special attention shall be made to protect the assembly from contamination, shock and impact damage.

The outside of the package shall be plainly and permanently labeled with at least the following information:

• Package identification number

• SELLER identification and address

• PROCUREMENT OFFICER’S contract number

• The COMPANY’s shipping address

• Attention: TPO or Equivalent

The SELLER shall notify the TPO of the shipping date not less than 15 business days before shipment.

6. APPLICABLE DOCUMENTS

• ASME.B31.3-Process Piping

• ASME.BPVC.VIII.1 -BPVC Section VIII-Rules for Construction of Pressure Vessels Division 1

7. ADDITIONAL DETAILS

7.1 Deviations

When time and/or cost is a consideration, the SELLER may communicate deviation requests directly to the COMPANY’s TPO and provide a copy to the COMPANY’s Procurement Officer.

The COMPANY’s TPO will evaluate the request and make recommendations to the COMPANY’s Procurement Officer, who will communicate acceptance, rejection, or partial acceptance to the SELLER. The request should identify the affected items, a description of the deviation, and justification. The deviation request shall be submitted to the TPO (copy the Procurement Officer) and approved by the TPO prior to making any change. The SELLER shall identify cost and schedule impacts for each deviation.

8. DELIVERABLES

SELLER shall provide a high-level schedule to the TPO within 30 days of award. TPO to provide acceptance in writing.

The TPO grants approval for SELLER to distribute SELLER’s Technical Specification to sub-suppliers for quote and procurement.

8.1 Submittals
