About the NNDC


The National Nuclear Data Center (NNDC) collects, evaluates, and disseminates nuclear physics data for basic nuclear research and applied nuclear technologies. The NNDC is a worldwide resource for nuclear data. The information available to the users of NNDC services is the product of the combined efforts of the NNDC and cooperating data centers and other interested groups, both in the United States and worldwide.

The NNDC specializes in the following areas:

There are currently 16 permanent staff members at the NNDC, including 11 with PhDs. The group includes scientific, professional, and support staff. Additionally, 6 people with a PhD degree work part-time under contract. The NNDC also hosts about 4 short-term visiting scientists and about 10-15 undergraduate interns per year.

Web Statistics

The NNDC has provided remote electronic access to its databases and other information since 1986.
Access via the Web started in 1994.
The figure below shows the time evolution of the number of electronic retrievals - web, telnet and FTP - from 1996 to 2020.


Nuclear Data activities started at BNL in 1952 under the Brookhaven Neutron Cross Section Compilation Group, changed to the Sigma Center in 1961, which became the National Neutron Cross Section Center in 1967 and finally the National Nuclear Data Center in 1977, providing a half-century of data and expertise to the world community.
The following people have served as head of the NNDC:
