Customer: Radioactive Materials Packaging Specialist
Scope Summary:
As the primary supplier, Oxford Engineering provided comprehensive Design for Manufacture (DfM) consultancy throughout the customer’s full engineering lifecycle for Class 1 nuclear transport containers. Structured design reviews were conducted across all development stages (L1–L5), from early conceptual layouts to production-ready documentation. The assemblies involved over 200 components, with particular emphasis on stainless-steel weldments, precision-machined housings, and specialised fasteners—all conforming to stringent nuclear containment requirements.
We placed strong focus on machining feasibility, tolerance stack-ups, and identifying ambiguous or impractical drawing features early in the lifecycle. Key areas of support included thread specification validation, finish note clarification, and material compatibility reviews—all tailored to ensure readiness for Class 1 nuclear standards.
Candidate’s Performance Against Targets:
- Provided detailed feedback preventing thermal deformation during TIG welding using FEA analysis
- Identified and resolved unachievable upper-level assembly features conflicting with part constraints
- Corrected GD&T interpretations across multiple drawing levels, improving design clarity
- Implemented modular design principles enabling shared tooling across part families
- Reduced drawing change orders by 40% compared to customer’s previous projects
Support Against Functional Objectives:
Our DfM expertise streamlined the engineering workflow by identifying high-risk tolerancing conflicts early, maintained product conformance with Class 1 nuclear containment requirements, enhanced production scalability with fewer drawing revisions, and reduced internal non-conformance reports by 35%, ensuring reliable containment performance for radioactive material transport.
