JOL's Friendly Enrichment Calculator

(last updated 22 Nov 2009)
This calculator is based on "JOL's Friendly Enrichment Program" and is provided here courtesy of J.O. Liljenzin .
Requires Netscape 3.0, Internet Explorer 3.0 or higher. JavaScript must be enabled. No warranty.
For optional viewing of the results in chart form, Netscape 4.0, Internet Explorer 4.0 or higher is required, and Java must be enabled (uses Java applet tChart ).

Performs detailed calculations for the enrichment of natural and reprocessed uranium by gaseous diffusion: mass balance, concentrations of minor isotopes, the additional enrichment required to compensate for the presence of the neutron-absorbing isotopes U-234 and/or U-236, cost, and optimum tails assay for minimum fuel cost.

Enter a value into any one field of the Material Balance, change any parameters as required, and click the "Calculate" button below. HELP
"t" means metric tonne.
