Form / Attachment / Pricing Sheet

This document contains technical drawings and specifications for the "HFIR GUIDE HALL 20 OPTICAL COMMON GUIDE FOR QUOTE". It provides detailed dimensional information and notes relevant to the fabrication and installation of this component.

• Overall layout and dimensions of the guide hall components, including transition tunnels and bulkheads.
• Specific dimensions for guide openings and edge-to-edge separations.
• Notes regarding tolerances, shielding, instrument shutters, cleaning requirements, and critical dimension approval.
• References to related documents, such as the Statement of Work (GHS-SW-20-0003).

This drawing is crucial for bidders to understand the physical specifications and geometric requirements of the guide system. It will inform quoting, design considerations, and manufacturing processes. Bidders must review these drawings to ensure their proposals accurately reflect the required dimensions and specifications.

Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the Statement of Work (SOW) for the High Flux Isotope Reactor (HFIR) Beryllium Reflector Replacement (HBRR) project, specifically focusing on the design, fabrication, and shipping of new neutron guides for the Cold Guide Hall.

• Phase 1: Design: Develop a final design for the neutron guide system, including conceptual and preliminary drawings, detailed specifications, and a test plan.
• Phase 2: Fabrication: Manufacture all guides according to the approved design, ensuring quality assurance, dimensional compliance, and surface compatibility. Testing of components will be performed.
• Phase 3: Shipping: Package and ship the fabricated guides to Oak Ridge National Laboratory.
• Phase 4: Installation (Optional): Provide oversight or actual installation work, with a separate quote required.

The scope covers guides within the HB-4 Tunnel, Transition Building, and Cold Guide Hall, including multiplex and single instrument guides with varying cross-sections and curves.

• Neutron reflectivity performance is defined using parameters such as QoNi, m-value, R(Q), and Ro. Specific m-value specifications are provided for each instrument guide (NB-1 through NB-6) in the appendices.

• Guides must be designed for a nominal operational lifetime of 20 years.

• Vacuum operation within chambers at less than 5x10^-2 torr.

• Substrate material must resist radiation and thermal stresses.

• Profile tolerance for super-mirror surfaces is ±0.03 mm.

• Angular misalignment tolerance between guide channels is less than or equal to 1.5 x 10^-4 radian.

• The document specifies phases for design, fabrication, and shipping. The final destination for shipping is Oak Ridge National Laboratory, Tennessee, USA.

• Guides will be housed within vacuum chambers (common or individual).

• Shielding will be provided around the guide layout.

• Materials and dimensions for guide segments are detailed in the appendices.

• The Contractor must adhere to a Quality Assurance Program (QAP).

• Specific meetings (Kick-off, Monthly, Conceptual Design Review, Preliminary Design Review, Final Design Review) are required throughout the project phases.
