This dataset compiles heat flow and temperature gradient data from over 44,000 wells across the United States, along with more than 6,000 related geothermal exploration resources. Originally assembled prior to 2014 for the now-retired National Geothermal Data System (NGDS), the collection includes curated well data, scanned field notes, temperature-depth curves, publications, maps, and other supporting documents. SMU Geothermal Laboratory contributed two different nationwide heat flow databases to the project. One is based on equilibrium temperature measurements (over 14,000 sites) and the other is based on corrected bottom hole temperature (BHT) data from oil and gas industry wells (over 30,000 sites). In addition, scanned field notes and temperature-depth curves were associated with approximately 6,000 specific sites in the heat flow database. Records were corrected and overlapping sites in the equilibrium heat flow database were linked between the original SMU National database and the UND Global Heat Flow database. New or related sites, which were not previously published because they lacked full heat flow content, are now included as gradient only information along with their detailed temperature data to fill in data gaps. Finally, SMU submitted over 920 scanned publications, reports, and maps suitable for full text searching. The dataset is provided in two flat-structured zip archives: one containing the curated well data and another containing related resources. An Excel index file is provided for each archive, allowing filtering by well name, location, and description. Data files are labeled with state or institutional origin where available.

The Knowledge Management Database (KMD) is a document repository that provides links to archived oil and gas documents as well as to reports stored in the DOE Office of Science and Technology (OSTI) library.

Introduction

This dataset is a curated collection of data related to nuclear energy, covering various aspects such as power plant locations and characteristics, uranium production, electricity generation, safety, and more. The data comes from reputable sources including the U.S. Energy Information Administration (EIA), World Resources Institute, Ember Climate, U.S. Nuclear Regulatory Commission (NRC), and Our World in Data.

Nuclear energy is a critical topic as countries around the world seek to decarbonize their electricity grids and combat climate change. At the same time, concerns around safety, waste disposal, and weapons proliferation lead to ongoing debate about the role nuclear should play in the energy transition.

This dataset enables in-depth analysis to inform these important discussions. Potential use cases include:

• Examining trends in nuclear energy generation and capacity over time and across geographies
• Benchmarking the safety record of nuclear compared to other energy sources
• Analyzing uranium production and prices to understand nuclear fuel dynamics
• Identifying major nuclear plant operators and parent companies
• Assessing the current and potential future role of nuclear in the electricity mix of various countries and regions

I encourage the Kaggle community to explore and build upon this dataset. Potential future collaborations could expand the dataset to include more granular plant-level data, detailed reactor specifications, waste and decommissioning data, country-level policy information, public opinion surveys, and more. I also welcome suggestions for additional datasets to include and new analytics projects and tutorials to undertake. Please do not hesitate to create threads in the "Discussion" or "Suggestions" sections. Together we can create a rich resource to power essential research and decision-making around nuclear energy. 🤗

This dataset contains files used to train and test the Multi-Configuration 23 (MC23) functional and to compare the results to other methods. It includes files to carry out electronic structure calculations. These include molecular geometries in xyz format, OpenMolcas input files for CASSCF calculations, converged CASSCF natural orbitals, OpenMolcas basis set files, and Gaussian 16 formatted checkpoint files for KS-DFT calculations. It also includes data used for data processing such as stoichiometries, absolute energies, and reference energies.

Each file in this dataset is a .tar.xz archive. One can extract them by the following command:

tar -xJf name_of_archive.tar.xz

Below is a description of the content of each archive.

gaussian_16_fchk.tar.xz contains Gaussian 16 formatted checkpoint files for all KS-DFT calculations used in this work. The files in the archive are named as functional/database/system.fchk

openmolcas_basis_set.tar.xz contains OpenMolcas basis set files used for multireference calculations. To reproduce the results in this work, the basis set files should be placed in the “basis_library” directory in the OpenMolcas installation location.

openmolcas_wave_function.tar.xz contains files needed by OpenMolcas to reproduce the CASSCF wave function used in this work. The files in the archive are named database/system.*.

• The file system.xyz contains the Cartesian coordinates. Note that for Data Set 2, the coordinates are in the input files system.inp.
• The file system.inp contains the OpenMolcas input file to perform CASSCF calculations.
• The files system.RasOrb, system.rasscf.h5, and system.rasscf.molden contain the converged CASSCF natural orbitals.

gaussian_16_stoichiometry_energy.tar.xz and openmolcas_stoichiometry_energy.tar.xz contain files used for data processing.

• Files with names like database.ref contain information used to calculate the final energies and errors. They are tab-delimited files. Each row represents an energy difference (e.g. atomization energy, barrier height, etc.). The first column contains the name of the energy difference (note: spaces may be present in this column). This is followed by the file names of each electronic structure calculation and the stoichiometries used to calculate the energy difference from the absolute energies. Each name or stoichiometry occupies one column. The second from the last column contains the reference value in kcal/mol. The reference values contain spin–orbit coupling. The last column contains the factor by which the final energy should be divided. This factor usually equals 1, but it can be greater than 1 for databases calculating atomization energies per bond or per atom.
• Files with names like method.elist contain the absolute energies of each electronic structure calculation. They are tab-delimited files. Each row represents an electronic structure calculation, and each row always contains two columns. The first column is the file name of the calculation in the format database/system. The second column is the absolute energy in atomic units extracted from the output file of electronic structure programs.
• The file named SOC.dat contains the spin–orbit coupling term in kcal/mol to be added to each electronic structure calculation prior to calculating energy differences. It has the same format as files with names like method.elist.

The database names in the directory names use a slightly different convention than the ones in the article describing MC23. A prefix DS2_ or DS3_ is used to indicate the data set to which a database belongs, and the number of data points is removed from the database name. For example, the MR-MGN-BE8 database from Data Set 2 has a file name DS2_MR-MGN-BE.

The Electric Vehicle (EV) charging permitting processes' database is a novel, multi-jurisdictional resource designed to contain the required codes and compliances in a structured database. Within this database are three tables, each structured with 287 columns, designed to capture detailed information spanning electrical, structural, zoning, and accessibility aspects, along with data regarding fees, reviews, and process durations. The database contains 99 state-level documents pertaining to 36 U.S. states, in addition to 87 county-level and 101 city-level documents, thus offering a complete overview of guidance and practices regarding permitting. The data was gathered via an Azure-hosted GPT-4o workflow, supplemented by targeted manual Google searches. State and county materials were located and extracted using the GPT-4o model. The Large Language Models (LLM) were used in conjunction with the decision tree framework with targeted prompts to extract the key information. The structured database incorporates Tables 1-3 included below as resources, as well as Table 4 which provides the scores for each document based on the scoring criteria in the paper (to be added after publication). The database can be used to compare and identify the patterns and trends in the requirements across different authorities having jurisdictions. This resource can be used by researchers, policymakers, and project teams. Note: LLMs are known to make mistakes in the interpretation of complex procedural documents and therefore no one should rely solely on this database to inform their own real-world EV infrastructure projects.
