The Nuclear Data Portal is a new generation of nuclear data services using modern and powerful DELL servers, Sybase relational database software, the Linux operating system with programming in Java. The Portal includes nuclear structure, decay and reaction data, as well as literature information. Data can be searched for using optimized query forms; results are presented in tables and interactive plots. Additionally, a number of nuclear science tools, codes, applications, and links are provided.

Core nuclear reaction database containing evaluated (recommended) data from the ENDF/B-VI library (also JEFF, JENDL, BROND, CENDL). It uses ENDF-6 format, covering all nuclides of practical relevance (328 in total) for neutrons up to 20 MeV and partly up to 150 MeV. It serves as principal input for neutronics calculations, including nuclear reactor design and operation, national security, criticality safety, accelerator design, radiation protection, radiotherapy, and detector simulation.

Core nuclear structure and decay database containing evaluated (recommended) data for 2,916 nuclides, organized in over 15,000 individual datasets. It serves as principal source of data for nuclear structure research, nuclear spectroscopy applications, databases MIRD and NuDat, and publications such as Nuclear Data Sheets and Table of Isotopes.

Nuclear reaction model code using various reaction mechanisms. It consists of a number of linked FORTRAN codes, input parameter libraries, a library of experimental data (CSISRS/EXFOR), and a friendly Graphic User Interface. It provides ENDF-6 formatted files.

Up-to-date ground and isomeric states properties of all known nuclides. It is used as a decay data standard by DOE Nuclear Materials and Safeguards System. A version tailored to Homeland Security needs is also available. It is distributed as a booklet and in Palm Pilot format.

A short description of the National Nuclear Data Center major Web Services that includes CINDA, CSISRS alias EXFOR, ENDF, ENSDF, MIRD, NSR, NuDat and XUNDL databases, CapGam and Empire tools, Nuclear Data Sheets and Nuclear Wallet Cards publications.
