Which nuclear power companies will achieve criticality before Aug 2026?

Research efforts encountered a technical error, preventing data retrieval. The primary research attempt to identify the Nuclear Regulatory Commission's (NRC) Combined License (COL) or Construction Permit (CP) bottleneck stage for leading US contenders (TerraPower, X-energy, Kairos Power) and historical review times for first-of-a-kind reactor designs was unsuccessful due to an internal server error. This technical impediment completely prevented the retrieval of any relevant information or data points.

No specific details or factual content were gathered. As a direct result of this server error, the report is unable to provide substantive answers, key data points, or detailed paragraphs concerning the original research inquiry. No specific details, metrics, or factual content related to bottleneck stages or historical review times for first-of-a-kind reactor designs could be obtained.

Additional attempts are required to gather comprehensive research findings. Overcoming this technical issue and obtaining the necessary information for a complete analysis and response will necessitate further attempts to access and process the research question.

An internal server error prevented the retrieval of research findings. The research process for determining the confirmed production and delivery schedule for Centrus Energy's High-Assay Low-Enriched Uranium (HALEU) fuel encountered an internal server error. This technical issue prevented the successful retrieval of any data or findings, indicating a problem within the system attempting to conduct the research rather than a lack of information on the topic itself.

Consequently, the research question cannot be answered at this time. As a direct consequence of the complete failure to access and process information due to the server error, no specific insights, metrics, or detailed summaries could be generated. Therefore, it is impossible to provide factual data points, analytical paragraphs, or definitively answer the initial research question regarding the HALEU schedule required by TerraPower Natrium and X-energy Xe-100 reactors, including its potential slack to accommodate a 3-to-6 month delay without impacting a Q2 2026 fuel loading date. Any subsequent research efforts would first necessitate the resolution of the underlying internal server issue to ensure data can be properly accessed and presented.

Specific findings for this research query were unobtainable. The research sought to determine the projected percentage of non-nuclear site preparation and infrastructure work (e.g., excavation, concrete foundations, turbine building) anticipated to be complete by December 31, 2025, for TerraPower's site in Kemmerer, Wyoming, and X-energy's site near Richland, Washington, based on public filings and county-level construction permits. However, an internal server error occurred during the research process, preventing the retrieval of any specific data or detailed information.

No data analysis or detailed information is available. Consequently, it is not possible to provide an analysis of key trends, data points, or contextual details regarding the construction progress for these projects. Further attempts would be necessary to resolve the technical issue and obtain the required information for this question.

The requested research could not be completed due to a technical system failure. An internal server error prevented the system from accessing or processing any information pertinent to the query.

No specific findings or data could be generated at this time. Consequently, no specific findings, data points, or analytical summaries could be produced. This issue indicates a technical problem within the research system rather than a lack of information on the topic itself, and it is advised to attempt the research again later.

An internal server error prevented the retrieval of requested research findings. A technical malfunction within the research system encountered an internal server error, which inhibited its ability to access or process the necessary information required to answer the specified research question.

No specific project milestones or stock data could be extracted. Consequently, no detailed data points, key metrics, or comprehensive summary paragraphs could be generated regarding the next three scheduled public-facing project milestones for the top two candidates. Similarly, no data was retrieved concerning the magnitude and direction of the stock price change for NuScale Power (SMR) within the five trading days following its last major NRC milestone announcement.

Findings remain unavailable until the server issue is resolved. The unavailability of these findings is directly attributed to the encountered internal server error. Research will be re-attempted once the underlying technical issue is resolved.
