Previous studies for UF6 limits in shipping containers were limited to enrichment up to 5%. The objectives of this new study will take that enrichment to 10%. The project will review the available literature and update these studies with current techniques, evaluate the impact of higher enrichments in safety criticality cases in transport conditions, and publish a report that will serve as the basis to the safety criticality analysis that will be provided for review and approval to the radioactive material transport regulators, for the DN-30 package with 30B cylinders containing enrichment higher than 5%.
This project focuses on the development, implementation, and initial validation of the STAR-CCM+® user-defined functionality for the two-fluid two-phase model (2F-2P). The focus will be on modeling two-phase boiling flow in realistic fuel-bundle geometries, including specific spacer geometries.
ESG has designed a cable routing system with connectors and EPA that protects cables from water exposure. This project will enable ESG to develop this technology to support current and future SMR designs.
The objective of this project is to determine the optimal casting process for the Lightbridge δphase U-Zr alloy using a depleted uranium (DU) zirconium surrogate in the Radiochemical Processing Laboratory (RPL) which is located at the Pacific Northwest National Laboratory (PNNL).
Westinghouse and Oak Ridge National Laboratory will use multiphysics design optimization methods and additive manufacturing to help develop new nuclear components as well as optimized replacements to existing components that are optimum for meeting design requirements and are manufacturable.
The scope of this project included the design of an experiment for irradiating Lightbridge metallic fuel material samples in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL).
General Electric-Hitachi, Argonne National Laboratory and the Idaho National Laboratory provided improved operational guidance for the current and advanced BWR off-gas system designs and identified off-gas system design improvements for use in BWR SMRs.
This project will enable NexDefense to evaluate their existing software on a production nuclear test bed, hence laying the path for future commercial adoption.
The objective of this project was to develop a simple system that allows control of a plant simulator from a workstation. Called the Task Engine for Job and User Notification (TEJUN, also the Japanese word for “procedure”), the system is a web-based application that allows procedures to be authored in an easy-to-read document format.
