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.

Hinkley Point C gets over $6 billion in financing from Apollo
U.S.-based private capital group Apollo Global has committed £4.5 billion ($6.13 billion) in financing to EDF Energy, primarily to support the U.K.’s Hinkley Point C station. The move addresses funding needs left unmet since China General Nuclear Power Corporation—which originally planned to pay for one-third of the project—exited in 2023 amid U.K. government efforts to reduce Chinese involvement.

A perturbation theory expression has been developed to predict the incremental detector output realized when traces of neutron-absorbing elements are present during prompt fission neutron uranium logging. The most restrictive constraint on the validity of the theory is that changes in the neutron flux caused by the presence of neutron absorbers must be small. Numerical evaluation of the theoretical expression appears feasible for experimental configurations that can be approximated by one-dimensional geometry.
