Determining Plutonium Mass in Spent Fuel Using ~(252)Cf Interrogation with Prompt Neutron

摘要

In order to determine Pu mass in spent fuel assemblies (FAs), thirteen NDA techniques were identified that provide information about the Pu composition of a fuel assembly (FA) as part of Next Generation Safeguard Initiative (NGSI) effort . A key point motivating the present research is the realization that none of these techniques, in isolation, is capable of quantifying the Pu mass of an assembly.
