AI Thread Summary
The composition of transuranics in commercial PWR spent fuel varies significantly due to different fuel cycle strategies employed by utilities, with typical discharge burnups around 55 +/- 5 GWd/tU. Older, cooler fuel is generally placed in dry cask storage, although newer high burnup fuel may be mixed with it. Resources such as the OECD NEA documents provide valuable data on spent fuel characteristics, including specific tables and figures that detail composition. The ORNL has also published relevant data in conjunction with the ORIGEN/SCALE package. For comprehensive insights, consulting these references is recommended.

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?

Thanks!

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

Very good, thank you Astronuc.

If anyone else has anything to add, please do.
 
Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information(power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.) for Material 2 is zero, while Material 1...
Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
