After being renamed the Sigma Center, the group was moved to the Reactor Physics Division of the Nuclear Engineering Department in the Brookhaven Lab in 1960.
In 1977, the Center was given the additional responsibility for nuclear structure and decay data by the Energy Research and Development Administration (ERDA), the predecessor of the Department of Energy, and its name was then changed to the National Nuclear Data Center.
[7] Since then, the head has been succeeded by Dr. Pavel Oblozinskiy, Dr. Michal Herman[8] and then Dr. Alejandro Sonzogni and presently Dr. David Brown.
In 2004, the NNDC began a modernization program which consisted of digitization of data and offering new web services.
