Written by GovTribe AI ·

This document is a technical drawing set for the HFIR Instrument CG-2 GP-SANS V-Cavity Magnetic Casing Assembly, a component for Oak Ridge National Laboratory's High Flux Isotope Reactor.

The assembly consists of multiple detailed engineering drawings (CG2-M-20-U-0018 through CG2-M-20-U-0030) that specify fabrication requirements for the complete casing system. Key components include: V-cavity aluminum walls (6061 aluminum), steel walls (A36 steel), magnetic casing magnet assemblies incorporating neodymium block magnets, borated aluminum shielding panels (31% boron-10 composition), steel lifting blocks, temporary aluminum plates for assembly, and various fasteners including stainless steel hex head cap screws and American Drill and Bushing swivel hoist rings. The assembly weighs approximately 71 pounds and uses electroless nickel coating per ASTM B733 specifications with 0.001-inch thickness classification SC3 (moderate service), Type 1, post-heat treatment Class 1. Critical fabrication notes specify handling precautions for neodymium magnets, material cleanliness requirements using water-soluble non-sulfurous cutting oils, deionized water rinsing, and specific packaging in polyethylene bags to prevent vacuum volume contamination. All drawings reference drawing number CG2-M-20-U-0018 as the parent assembly with revision 0 dated October 22, 2025, and prohibit vendor substitution without prior engineering approval. Tolerances follow ASME Y14.100 drafting standards and Y14.5 geometric dimensioning specifications.
