117. Multi-MOX: Facilitating plutonium multi-recycling in the French PWR fleet

Gulla Torvund (University of Oslo)

18/06/2025, 11:00

Oral presentation

This study examines the Multi-MOX (MMOX) strategy for plutonium multi-recycling in PWRs using the CLASS fuel cycle simulation tool. MMOX involves blending reprocessed plutonium from various sources to produce viable fresh nuclear fuel. While MMOX significantly curtails the growth of the plutonium inventory, it does not stabilize it entirely in the long term. Although lower burnup reduces...

126. The Role of Analytical Methods in Electrical Loss Calculations for High-Voltage Armored Three-Core Power Cables

Martin Hovde (Nexans Norway AS)

Oral presentation

For large high-voltage power cables, such as the export cables connecting offshore windfarms to shore, a key design challenge is calculating the cable’s current-carrying capacity: the maximum current it can carry without exceeding a specified temperature limit. For complex cable designs, such as three-core cables with metallic screens and steel-wire armor, commercial Finite Element Method...

155. Clustering in nuclei and its effects on the stellar nucleosynthesis

18/06/2025, 11:30

Oral presentation

Clustering in nuclei is an emergent phenomenon, whereby nuclei tend to aggregate (or cluster) into various components. In light nuclei, this phenomenon is postulated to manifest notable properties such as dilute density structures and even Bose Einstein condensates. Cluster states can also have significant effects on scattering cross sections, particularly at low energies. Modelling clustering...

157. Studying the astrophysically crucial 12C(α, γ)16O reaction at high temperatures

Jeppe Thingholm (University of Oslo)

18/06/2025, 11:45

Oral presentation

One of the major processes in stars is helium burning, which consists of two main parts that produce $^{12}\mathrm{C}$ and $^{16}\mathrm{O}$. Helium burning is the primary source of $^{12}\mathrm{C}$ and $^{16}\mathrm{O}$, the two most abundant elements after hydrogen and helium. The second part of helium burning is the process of an $\alpha$ particle being captured by a $^{12}\mathrm{C}$...
