The handling of ENDF-6 files is often perceived as cumbersome, especially regarding their creation. The Python package endf-parserpy has been created with the objective of providing a handy tool to facilitate the interaction with ENDF-6 files. This contribution will present design considerations and capabilities of this package.
Nuclear data processing systems need to be used to convert evaluations in the Evaluated Nuclear Data Files (ENDF-6) format into forms useful for practical applications. Each application, dedicated analysis, assessment that rely on nuclear data have specific, sometimes unique nuclear data form needs, requirements and priority. Nuclear data portals are no exception and require specific,...
This presentation explains the nuclear data editing and drawing functions of FRENDY. FRENDY has editing functions to modify nuclear data files and to confirm processing results. Though many nuclear data processing codes have such functions, they can not process the nuclear data, e.g., resonance reconstruction, linearization, and Doppler broadening. If users want to edit nuclear data files,...
The EXFOR Interface (x4i) is the only python API available for the EXFOR library. In this talk, we provide an update on recent improvements to x4i. Recently x4i was significantly updated to use pint-PANDAS to manage the EXFOR DATA and COMMON fields and to parallelize the indexing of the EXFOR library. X4i also use the new EXFOR Master File and EXFOR dictionaries. Finally, x4i is now hosted...
We will provide an update on nascent efforts to compile for Neutron Science References using Large Language Models.
Cosmic-ray muons are constantly bombarding us on the ground. When a negative muon comes to rest in matter, it is captured into an atomic orbit and, with a certain probability, is subsequently absorbed by the atomic nucleus via the weak interaction. This process is known as muon nuclear capture (µNC). In this process, most of the muon's rest energy is carried away by a muon neutrino and the...
The National Nuclear Data Center (NNDC) at Brookhaven National Laboratory (BNL) has developed NuDat, a powerful web application enabling users to explore comprehensive databases of nuclear structure, nuclear decay, and neutron-induced nuclear reaction data. As the primary interface for querying, visualizing, and disseminating data from the Evaluated Nuclear Structure Data File (ENSDF), NuDat...
The Laboratoire National Henri Becquerel is the French national metrology laboratory for ionizing radiation, in charge of the definition of the derived SI units – the becquerel (activity) and the gray and sievert (absorbed dose and dose equivalent) and their transfer to users. In order to define the becquerel with high precision, decay data are of utmost importance and an accurate knowledge of...
Standardizing data and unifying data access in the nuclear field opens a new dimension of data usage, especially in the age of machine-learning. For the development of those standards and infrastructures we should build on existing tools and established standards and infrastructures as much as possible, exploiting implicit knowledge present in existing technologies.

The National Nuclear Data Center (NNDC) at Brookhaven National Laboratory (BNL) has recently released ENDF/B-VIII.1, the latest version of the Evaluated Nuclear Data File (ENDF) library. Produced, distributed, and endorsed by the Cross Section Evaluation Working Group (CSEWG), ENDF/B-VIII.1 represents the most current and comprehensive evaluated nuclear data resource, designed for a wide range...
The National Nuclear Data Center (NNDC) at Brookhaven National Laboratory (BNL) has recently undertaken a significant modernization of the Evaluated Nuclear Structure Data File (ENSDF) format, transitioning from a legacy 80-column ASCII format to JSON. This new hierarchical JSON format leverages a modern format consisting of key-value pairs, enabling efficient data organization, flexibility,...
