ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

A vectorized source algorithm was developed for the Electric Power Research Institute light water reactor core nodal code SIMULA TE-E. The existing line successive displacement scheme was replaced by configuring the source for all nodes in a given plane as a single vector that could be computed simultaneously. Power distributions and eigenvalues for all test problems agreed exactly with the original scalar code. A factor of 2 to 7 reduction in execution time was achieved for typical pressurized water reactor problems on the CYBER 205.
