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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

This technical note models the concept of fuzziness along with the stochastic behavior of the point-kinetics neutron equation. The fuzzy stochastic model is investigated numerically by extending the Euler-Maruyama method to fuzzy form. The uncertain neutron density and delayed neutron population are obtained and compared with Monte Carlo and stochastic principal component analysis solutions. Various combinations of fuzzy parameters are considered, and the uncertain neutron density and delayed neutron population are obtained in different cases. Finally, the sensitivity of these fuzzy parameters with stochastic behavior is investigated.
