Different techniques for reducing DLOFC fuel temperatures in a PBMR-DPP-400 core

Tchonang Pokaha, Marius; Serfontein, Dawid E. (Elsevier, 2018)

This article addresses the topic of modifying the fuel cycles of Pebble Bed Reactors in order to reduce their maximum fuel temperatures during Depressurised Loss of Forced Coolant (DLOFC) accidents, in order to prevent ...
Neutron poison distribution in the central reflector to reduce the DLOFC temperature of a Th-LEU fueled OTTO PBMR DPP-400 core

Pokaha, Marius Tchonang; Serfontein, Dawid E. (Taylor & Francis, 2018)

In a previous study using a mixture of thorium and 20 a/o% LEU at 16 gram per fuel sphere heavy metal loading and adjusting the effective fuel enrichment to produce the same amount of cumulative energy per fuel sphere as ...
Using thorium to reduce the maximum fuel temperatures during depressurized loss of coolant accidents in a once-through-then-out (OTTO) PBMR DPP-400 core

Tchonang Pokaha, Marius; Serfontein, Dawid E. (Taylor & Francis, 2017)

This article presents the results for the PBMR-DPP-400, but for a once-through-then-out (OTTO) refueling scheme. An optimization attempt of the axial and radial power profiles is reported. The main aim was to reduce the ...
