Hello, I am looking for a resource on the composition of transuranics in a typical commercial PWR after the fuel is cycled and put into dry cask storage. Anyone have material on this?
Very good, thank you Astronuc.There isn't a typical example of PWR spent fuel, because each utility has a different fuel cycle strategy. But discharge burnups are around 55 +/- 5 GWd/tU.
See page 51 of this document - https://www.oecd-nea.org/science/pubs/2006/nea6224-burn-up.pdf
In the US, it's usually the older cooler fuel that gets placed in dry storage, but sometime more recent high burnup fuel will be mixed with older cooler fuel of lower burnup.
ORNL has published some data on spent fuel in conjunction with the ORIGEN/SCALE package.
Very good reference: See Table 1, 3 and Figure 7 and list of references
