Description
The Second Target Station (STS) is currently in the preliminary design phase at the Oak Ridge National Laboratory (ORNL). STS will significantly expand the existing capabilities of the Spallation Neutron Source (SNS) at ORNL by constructing a new target station that utilizes the Proton Power Upgrade (PPU) enhanced SNS accelerator to make STS the world-leading peak brightness source for cold neutrons.
Since the completion of the conceptual design phase in 2021, significant advances in the design of the Target Systems components have been made and some of these advances will be presented. Considerable R&D design, prototyping and testing has been completed validating novel moderator manufacturing. Substantial cost control actions have also been implemented and more are in progress, including cryogenic moderator system simplification, reduction of component cooling loops and monolith shielding composition changes.
The STS technical systems have made excellent progress towards the start of preliminary design reviews scheduled in 2024. Key decisions and design choices have been made. The cost savings identified do not affect the STS Key Performance Parameters (KPPs). Looking ahead, STS is committed to seek efficiencies and scope optimization to limit cost growth while maintaining technical capabilities of the new facility.
