FRAM (Fixed-Energy, Response Function Analysis with Multiple Efficiency) software is a code used primarily to determine the isotopic composition of plutonium in special nuclear materials.
The Features
- Determines relative plutonium isotopic abundances or uranium isotopic abundances in non-destructive assay applications
- Uses spectra collected with HPGe detectors
- Incorporates a sophisticated peak fitting and multiplet deconvolution algorithm to analyze complex peak regions
- Requires no efficiency calibration for matrix density, thickness or container characteristics
- Developed by Los Alamos and licensed to Mirion
