End of Enrichment Reconstruction
The age and composition of special nuclear material (SNM) offers a great deal of forensic information; e.g., likely producer or country of origin. Nuclear materials (nuclides) decay at different rates, often in a chain fashion; therefore, the composition of the nuclides changes over time. Trace nuclides in special nuclear material often carry more information regarding age and original composition, but trace nuclides can be easily lost in 'approximations.' Current decay calculation technology is based on a matrix Taylor approximation that is imprecise in nature and time-consuming to compute. Better computational technology for decay calculation and age estimation is needed. This project offers better Nuclear Forensics technology solutions for these needs.
