For those needing portability, Rad Pro for Desktop works with Windows 8.1 tablets (just tested). Will not work with Surface tablets running Windows RT.

These uranium fuel loading calculations are based on the empirical data formulas developed for the uranium enrichment calculator.  These calculations are mainly used by nuclear engineers during reactor design.  Although they are not a typical radiation protection calculation, the calculator is included by special request from nuclear engineers.  To see and read more about the enrichment formulas, read the white paper on this site available by clicking the "Documents/U Enrichment" button.
