| Estimating the Value of Nuclear Integrated Hydrogen Production and the Dependency of Electricity and Hydrogen Markets on Natural Gas, INL/RPT-23-73909 | The purpose of this work reported herein was to specify, design, build, demonstrate, and deploy a simplified user-friendly NPP-HTSE hydrogen profitability analysis tool to provide utility companies operating NPPs with a quick and semi-intuitive interface to evaluate the opportunity of integrating HTSE hydrogen production with existing LWR NPPs. | | 8/23/2023 |
| Production of Fischer-Tropsch Synfuels at Nuclear Plants, INL/RPT-22-69047 | A case study analysis was performed to evaluate nuclear-powered synthetic fuel production in the midwestern US. A Fischer-Tropsch fuel synthesis plant design was used as the basis for the analysis. The FT plant design was configured to produce a product slate consisting of diesel fuel, jet fuel, and motor gasoline blend stocks from CO2 and H2 feedstocks. The CO2 feedstock for the FT plant was assumed to be sourced from biorefineries in the region around a Midwest LWR NPP. The analysis specifies that power from the LWR is used to produce H2 via high-temperature steam electrolysis and to operate the FT synfuel production plant. | | 9/30/2022 |

| Flexible Plant Operation and Generation Probabilistic Risk Assessment of a Light-Water Reactor Coupled with a High-Temperature Electrolysis Hydrogen Production Plant, INL/EXT-20-60104 Revision 1 | This report details an expansion of the original two generic probabilistic risk assessments (PRAs) for the addition of a heat extraction system (HES) to a light-water reactor, one for a pressurized-water reactor and one for a boiling-water reactor. The new material in this revision includes a new HES design, direct electrical coupling of the nuclear power plant to the High-Temperature Electrolysis Facility (HTEF), and a smaller 100-MWt HTEF analysis. The results investigate the applicability of the potential licensing approaches, which do not require a full United States Nuclear Regulatory Commission licensing review.

| Report on the Creation and Progress of the Hydrogen Regulatory Research Review Group, INL/RPT-22-66844, Revision 2 | FPOG Pathway is developing options to help U.S. NPP in all these areas to enable NPPs designed for steady baseload operation to integrate with intermittent wind and solar capacity to assure reliable clean energy for the nation.

| Risk Analysis of a Hydrogen Generation Facility near a Nuclear Power Plant, SAND2023-07884 | The intent of this study is to investigate the risk of a hydrogen production facility in close proximity to an NPP. A 100 MW, 500 MW, and 1,000 MW facility are evaluated herein. Previous analyses have evaluated preliminary designs of a hydrogen production facility in a conservative manner to determine if it is feasible to co-locate the facility within 1 km of an NPP. This analysis specifically evaluates the risk components of different hydrogen production facility designs, including the likelihood of a leak within the system and the associated consequence to critical NPP targets. This analysis shows that although the likelihood of a leak in an HTEF is not negligible, the consequence to critical NPP targets is not expected to lead to a failure given adequate distance from the plant. | | 8/15/2023 |
| Simulation of Power Dispatch from a PWR/SOEC System for Contingency Reserves, INL/RPT-23-73164 | This report describes simulations that were performed to verify that a NPP tightly coupled to a SOEC hydrogen production plant can qualify for participating in non-spinning and spinning and contingency reserve markets by providing spinning reserve power to the bulk electric grid in less than 10 minutes. Previous work with Sargent & Lundy developed a preliminary design and cost estimate for coupling an NPP to a 500 MW nominal SOEC plant, and this work builds on that effort by simulating their combined dynamic operation in a representative grid environment. For the simulations, a 4-loop PWR plant and a solid oxide electrolysis plant were modeled in Matlab/Simulink and connected to a representative grid modeled in RSCAD. | | 6/29/2023 |
| Heat Balance Model Analysis and Equipment Assessment for 30% Thermal Extraction from a Nuclear Power Plant | As non-dispatchable renewables, predominantly wind and solar, continue to penetrate U.S. energy markets, economic and capability challenges are becoming increasingly prevalent for traditional baseload generators, such as nuclear power plants. These pressures have led to decreased efficiencies and closures for nuclear plants which are vital to meeting national decarbonization goals. In an attempt to maximize efficiency and
maintain the existing nuclear fleet, new ways to integrate energy systems are being sought after. | | 6/1/2023 |
| Risk Analysis of a 100 MW Hydrogen Generation Facility near a Nuclear Power Plant, SAND2023-04192 | Nuclear power plants (NPPs) are considering flexible plant operations to take advantage of excess thermal and electrical energy. One option for NPPs is to pursue hydrogen production through high temperature electrolysis as an alternate revenue stream to remain economically viable. The intent of this study is to investigate the risk of a 100 MW hydrogen production facility in close proximity to an NPP. Previous analyses have evaluated preliminary designs of a hydrogen production facility in a conservative manner to determine if it is feasible to co-locate the facility within 1 km of an NPP. This analysis specifically evaluates the risk components of a 100 MW hydrogen production facility design, including the likelihood of a leak within the system and the associated consequence to critical NPP targets. This analysis shows that although the likelihood of a leak in an HTEF is not negligible, the consequence to critical NPP targets is not expected to lead to a failure given adequate distance from the plant. | | 5/25/2023 |

Development and testing of NPP simulators addresses two principal LWRS needs. First, testing of simulators with human operators in real-time provides validation of the concept-of-operations to ensure the modifications to the nuclear power plant enable achieving the intended objectives of rapid dispatch of both thermal and electric power while not compromising safety, including human factors considerations. Second, testing the simulators in real-time with human operators and physical hardware-in-the-loop verifies the functionality and safeguards in the proposed control systems. | | 12/14/2022 |
| Report on the Creation and Progress of the Hydrogen Regulatory Research Review Group, INL/EXT-22-02126 Revision 1 | H3RG was formed to begin identification of the generic technical and safety risks that could be accepted under a 10 CFR 50.59 evaluation and thus avoid the uncertainty of the LAR process.
