High-Temperature Gas-Cooled Reactor Research Survey and Overview: Preliminary Data Platform Construction for the Nuclear Energy University Program

Abstract

Since the U.S. Department of Energy Office of Nuclear Energy initiated the Nuclear Energy University Program (NEUP) in 2009, there are 29 NEUP projects focusing on high-temperature gas-cooled reactor (HTGR) research up to July 2022. The resultant research product, either experimental or computational, were published as final NEUP reports, journal articles and conference proceedings. However, these federally funded products have been scattered and sometimes cannot be easily accessed.To improve access to this valuable HTGR validation data and optimize the return on the significant investment made by the Department of Energy, the Advanced Reactor Technologies (ART) Gas-Cooled Reactor (GCR) program started a survey of completed and ongoing HTGR NEUP projects to develop a public-access database specific for HTGRs applications that can be used to retrieve computational fluid dynamics and system code validation data. This effort will help guide future NEUP-funded research, define new state of the ART Phenomena Identification and Ranking Table (PIRT), and promote the usage of this data in the codes validation matrices. This report provides an overview of the NEUP-funded HTGR-related research projects from Fiscal Year (FY) 2009-2021 and identifies validation knowledge gaps still existing in HTGR thermal-fluid research.A preliminary data platform has been developed for the 29 NEUP projects investigating HTGR thermal hydraulics, including their final reports as well as the available scientific publications. As an ultimate goal for this work, the ART-GCR program will create a central database at Idaho National Laboratory to identify, organize, and store these datasets generated by experimental investigations or computational models, experimental facility descriptions, and publicly-available academic products from the HTGR-related NEUP projects and provide future guidance for the storage and transmission of important project documentations for later NEUP projects as well.

Developing PCC and DCC integral effects test experiments at the High Temperature Test Facility

“…Furthermore, up to July 2022, there were over 29 completed and ongoing United States Department of Energy Office of Nuclear Energy Nuclear Energy University Program (DOE NEUP) projects focusing on HTGR related research. These projects scopes, associated test facilities, test matrixes, and main findings are outlined in the INL Report: "High-Temperature GasCooled Reactor Research Survey and Overview: Preliminary Data Platform Construction for the Nuclear Energy University Program" (Qin et al, 2022). As a part of these efforts, Oregon State University (OSU), under the auspices of the Idaho National Laboratory (INL) and the United States Department of Energy (DOE), assembled an integral test facility, the High Temperature Test Facility (HTTF) that delivered experimental data to validate thermal-hydraulic system codes used for nuclear reactors safety analyses.…”
