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.

The problem of critical dimensions of an infinite-slab multi-layer multiplying system can be solved by a general procedure due to K. M. Case. The angular neutron distribution and the critical core size can then be found by solving the Fredholmtype integral equation with an additional critical condition. Numerical calculations have been done for the case of a multiplying slab surrounded by an infinite reflector, assuming one-energy group and isotropic scattering of neutrons, the mean number of secondary neutrons per collision in a medium-c being a variable parameter. Various approximations of the exact solution have been compared and the asymptotic theory has been found applicable in a wide range of c values in both media. 272
