ROI Calculation Logic

By reducing the proportion of over-evaluated radioactive waste from 15% to 5%, this technology could properly classify waste that was previously over-evaluated. This could reduce waste treatment costs by ~$65K/year (AI est.) based on 100 tons/year at ~$6.5K/ton (AI est.). Additionally, improved measurement accuracy could reduce re-measurements and analyses, leading to a ~$15K/year (AI est.) efficiency gain from evaluation staff costs (5 staff × ~$50K/staff (AI est.)). Total estimated annual cost savings could reach ~$80K (AI est.).
