235U requirements.

Unit EPR-type PWRa U5-FR [6]
235U enrichment % 4.9 14.4
Mass of 235U in core Tonnes of 235U/GWe 3.9 8
Reloading Tonnes of 235U/GWe/year 0.78 1.4b

We chose the characteristics of the EPR for comparison with an SR (assumptions may differ in relation to Ref. [6]). The figures are given in relation to an equilibrium cycle.


For the first 5 reloads of an U5-FR. The U5 enrichment is given for the first core: it constantly decreases as the U5-FR becomes a Pu-FR.
