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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

Advanced modeling and simulation tools, such as encompassed by the VERA code suite, are characterized by high fidelity, high simulation capabilities for modeling coupled, multiphysics phenomena. Within CASL, a significant effort has been expended, especially in the areas of code and solution verification, to identify areas for code enhancement to further mature the VERA code suite predictive capabilities. More recently, CASL and the NRC have completed a collaboration on the use of advanced modeling and simulation tools in a regulatory environment. Modern VVUQ methods are proving essential to establish the necessary level of credibility for application of predictive computer simulation tools in a regulatory environment. This panel will discuss VVUQ and modeling and simulation in a regulatory environment.
