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 external link).

Calculate material, energy, and CO2 emission balance for the front end of the nuclear fuel chain, assuming that the uranium feed is generated from re-enrichment of depleted uranium tails.

Enter a value into any one field of the flow chart and click the "Calculate" button below. HELP new window
"t" means metric tonne.
