Abstract
| Fixed-energy Response-function Analysis with multiple efficiency (FRAM) is a software code designed primarily for plutonium and uranium isotopic analysis. It is widely used in the domestic and international safeguards community. FRAM can quickly and accurately determine the isotopic compositions of plutonium, uranium, and mixed oxides (MOX) when measuring with a high-purity germanium (HPGe), cadmium zinc telluride (CZT), or lanthanum bromide (LaBr3) detector. The capability of FRAM has been enhanced to measure the mass of plutonium, uranium, and MOX. Both the isotopic composition and mass of the item can be quickly determined with one measurement using a gamma detector with the upgraded FRAM. This paper will present the operation and performance of the upgraded FRAM v.7, which is scheduled for copyright in mid 2024 and release in early 2025. |
