Overview of high-temperature fuel behaviour with relevance to CANDU fuel

Uranyl Ion Extraction with Conventional PUREX/TRUEX Ligands Assessed by Electroanalytical Chemistry at Micro Liquid/Liquid Interfaces

“…The continued debate over climate change has sparked a resurgence of interest in alternative energy resources to replace fossil fuels, included in these is nuclear power generation. One of the most effective nuclear power generation techniques has been the Canadian Deuterium Uranium (CANDU) heavy water reactors, owing to their capability to utilize natural sources of uranium and even spent nuclear fuel from conventional light water reactors. − This ability stems from the high efficiency of neutron capture within the deuterium heavy water system and the use of materials, such as zirconium, which have a minimal neutron absorption cross-section . Fission products, however, have high neutron absorptions and limit the lifetime of the fuel bundle despite the continued presence of significant fissile material .…”

Artificial neural network modeling for fission gas release in LWR UO2 fuel under RIA conditions

“…On the other hand, for the case that fuel failure occurs at high enthalpy under a RIA event, the source term should be analyzed using test results obtained at high enthalpies leading up to fuel fragmentation or melting [39]. …”

Thermal Aspects of Conventional and Alternative Fuels in SuperCritical Water-Cooled Reactor (SCWR) Applications

“…CANDU reactors use collapsible sheath, which leads to small fuel-sheath gaps approximately 20 µm (Lewis et al, 2008). Moreover, Hu and Wilson (2010) have reported a fuel-sheath gap width of 36 µm for a proposed PV SCWR.…”
