First of a Kind (FOAK) Nuclear Demonstration Readiness Projects: Advancement of High Temperature Gas Cooled Reactors for Grid-Scale Applications: Xe-100 Conceptual Design and Risk-Informed Licensing

The Xe-100 Concept Finalization (XeCF) project will accelerate deployment of advanced reactors (ARs) by enabling completion of X-energy’s grid-scale high-temperature gas-cooled reactor (HTGR) conceptual design while applying the risk-informed, performance-based (RIPB) licensing framework. Project scope is organized around four tasks:

• Provide project coordination, to include administration, configuration, document, subcontract, and financial management; scheduling; and project controls support to ensure deliverables and milestones are achieved.
• Perform regulatory development through NRC engagement on key topics, including: 1) Execute the RIPB framework in support of conceptual design; 2) Develop white papers to familiarize the NRC staff with the Xe-100 design; 3) Execute the technology-inclusive concept of application (TICAP) framework with the completed, mature Xe-100 concept design; and 4) Administer an Appen. B Quality Assurance Program.
• Define the requirements and functions that an economically competitive, licensable, low-technology risk advanced reactor must meet in order to comply with DOE AR demonstration project, electricity, and process heat customer needs.
• Complete the Xe-100 Reactor/Plant Conceptual Design, to include finalizing the Xe-100 functional baseline to demonstrate that the system can achieve the required performance and programmatic goals; and conducting design, modelling, and simulation analyses to mature all Xe-100 reactor/plant systems, structures, and components (SSCs). At completion, conduct an external Basic/Final Design Readiness Review.
