| 摘要 |
The invention provides an improved method of manufacturing fuel by blending fuel from different sources in a way which accounts for the isotopic variation in the fuel from different sources. In particular, the invention provides a method for producing nuclear fuel, the method comprising defining one or more reference composition for fuel to be produced; providing two or more amounts of feed fuel material from which to produce the fuel, defining the deviation of each of the amounts of feed fuel material from a reference composition; selecting and mixing masses of feed fuel material from two or more of the amounts of feed fuel material, the masses being selected to give a lower deviation between the mixed feed fuel material and the selected reference composition than between the feed fuel material amounts, and the selected reference composition, the deviation being defined by a function based on the isotopic composition of the feed fuel material amounts.
