Responsibilities
Create relevant 3D CAD models and detailed 2D drawings of various equipment, equipment integration, plant layout, structures, systems and/or components (based on assigned project). These may include, but are not limited to: process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), isometric drawings (Isos), piping arrangements, equipment arrangements, etc
Assess models for manufacturability as well as assembly and integration considerations
Perform a variety of design/drafting activities for the engineering group including preparing and updating manufacturing drawings
Serve as an information source on planning and design of equipment installations: equipment and plant engineering
Maintain notes, design calculations and other documentation (e.g., drawings, bills of materials, lists of design parameters, and performance guarantees) for current and future reference
Identify and follow XE processes, procedures, and guides, as well as best CAD modelling and drafting practices, and maintain communication with other team members to ensure the consistency and standardization of practices and design
Collaborate in planning, scheduling, and organization of detailed phases of engineering work
Adhere to filing guidelines for drawings to maintain up-to-date drawings
Maintain system and model compatibility in X-energy’s Product Lifecycle Management (PLM) system and Plant Design Environments (PDE), including the 3D CAD applications
The role may include specialization in one or more of the following areas: Component, System Design: Work closely with the responsible engineers to develop mechanical/ physical concepts, designs, and processes to create SSCs related to the project to which they are assigned. Assist in the definition and development of system/component geometric interfaces. Incorporate 3D representations of components into the plant model and verify compatibility with connecting interfaces. For FOAK design, create and check manufacturing technical data packs and 2D detail component drawings to ensure fabricated components are produced in accordance with the design specifications. For FOAK design, ensure SSCs are properly designed and integrated into the design of the overall system and/or plant to meet their component level functions and requirements. For FOAK design, engage vendors in the design and manufacturing of defined and package systems and their related components. Show initiative in suggesting design changes and improvements to the design of components, factoring in Design for Manufacturing (DFM) and Design for Assembly (DFA) principles. Equipment/Plant Layout Integration Design: Utilize S3D (formerly SmartPlant 3D) to create 3D piping design models within and supporting the SMR plant, including but not limited to equipment layout, pipe routing, pipe support design, maintenance and accessway volumes. Utilize NX or other CAD software to develop 2D and 3D component designs. Maintaining and checking the S3D model to ensure accuracy, and resolution of interferences. Creating Piping isometrics, general equipment layout drawings, material take off lists etc. Application of piping best practices and principles when routing piping. Support procedure inputs and reviews as required. Building relationships that will facilitate knowledge transfer, cross functional knowledge of related work groups, and ability to present work products effectively
