Thermalhydraulics of advanced 37-element fuel bundle in crept pressure tubes
EPJ Nuclear Sciences & Technologies, 2016 A CANDU-6 reactor, which has 380 fuel channels of a pressure tube type, is suffering from aging or creep of the pressure tubes. Most of the aging effects for the CANDU primary heat transport system were originated from the horizontal crept pressure tubes.

Monte Carlo Few-Group Constant Generation for CANDU 6 Core Analysis
Science and Technology of Nuclear Installations, 2015 The current neutronics design methodology of CANDU-PHWRs based on the two-step calculations requires determining not only homogenized two-group constants for ordinary fuel bundle lattice cells by the WIMS-AECL lattice cell code but also incremental two ...

Power flattening in the fuel bundle of a CANDU reactor
Nuclear Engineering and Design, 2004 Abstract The strong non-uniformity of the fission power production density in the CANDU fuel bundle could have been mitigated to a great degree. A satisfactory power flattening has been achieved through an appropriately evaluated method by varying the composition of the LWR spent fuel/ThO2 mixture in a CANDU fuel bundle in radial direction and ...

Realistic thermal analysis of the CANDU spent fuel dry storage canister
Nuclear Engineering and Technology, 2023 Thermal analysis of the CANDU spent fuel dry storage canister is very important to ensure the integrity of the spent fuel. The analyses have been conducted using a conservative approach, with a particular focus on the peak cladding temperature (PCT) of ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
