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!
Thanks!
Astronuc said: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

Commercial transuranic waste composition refers to the materials and substances that make up waste generated from commercial activities that contain transuranic elements. These elements have an atomic number greater than 92 and are mostly man-made, with the most common being plutonium and neptunium.
The main sources of commercial transuranic waste include nuclear power plants, research facilities, and nuclear fuel processing plants. These facilities produce waste through the use of transuranic elements in various processes.
Commercial transuranic waste composition is determined through various methods, including chemical analysis and radiological measurements. These methods help identify the specific types and quantities of transuranic elements present in the waste.
The health and environmental risks associated with commercial transuranic waste can vary depending on the type and amount of waste present. However, these risks can include radiation exposure, contamination of soil and water, and potential long-term health effects for humans and wildlife.
Commercial transuranic waste is typically managed and disposed of through a combination of methods, including storage, treatment, and disposal. The most common disposal method is through deep geological repositories, where the waste is permanently stored in underground facilities designed to contain the waste and prevent any potential release into the environment.
