(3) The deployment of an advanced converter beginning in 1995 will not signifi-<br />

cantly increase <strong>the</strong> maximum installed capacity if <strong>the</strong> U308 supply is limited to 3.0<br />

million ST below $160/lb. This is primarily due to <strong>the</strong> fact that a significant amount<br />

of <strong>the</strong> U308 supply has been committed to <strong>the</strong> standard LWR prior to <strong>the</strong> advanced converter<br />

attaining a large fraction of <strong>the</strong> installed capacity. If <strong>the</strong> U308 supply should be as<br />

large as 6.0 million ST below $160/lb, <strong>the</strong>n <strong>the</strong> effect of <strong>the</strong> advanced converter is<br />

considerably larger.<br />

(4) An advanced enrichment process capable of economically reducing <strong>the</strong> tails compo-<br />

sition to 0.0005 could have a greater effect than improvements in LWR U308 utilization or<br />

<strong>the</strong> deployment of an advanced converter.<br />
