Progress in Nuclear Energy

The 2011 Fukushima nuclear accident highlighted the need for thorough safety assessments of nuclear power plants, especially in the context of multi natural hazards that may occur simultaneously or sequentially. With climate change increasing both the frequency and intensity of natural hazards like typhoons, tsunamis, and extreme weather events, external event risk assessment frameworks have beco…

CANDU reactors have fuel channels consisting of 12-13 CANDU fuel bundles, and the rotational angle of each fuel bundle is not controlled when it is loaded into the channel. Coolant behaviour, which may be affected by bundle rotational misalignment, can influence fuel performance; however, the degree of this impact is not yet well understood. This work performed Computational Fluid Dynamics (CFD) …
