Assessment and reduction of proliferation risk of reactor-gradeplutonium regarding construction of ‘fizzle bombs’ by terrorists
Serfontein, Dawid E.; Mulder, Eben J.; Reitsma, Frederik (Elsevier, 2014)The approximately 23.7 wt% 240Pu in reactor-grade plutonium denatures the 239Pu to the extent that it cannot fuel high yield nuclear weapons. 240Pu has a high spontaneous fission rate, which increases the spontaneous neutron ... -
A generic method for automatic translation between input models fordifferent versions of simulation codes
Serfontein, Dawid E.; Mulder, Eben J.; Reitsma, Frederik (Elsevier, 2014)A computer code was developed for the semi-automatic translation of input models for the VSOP-A diffusion neutronics simulation code to the format of the newer VSOP 99/05 code. In this paper, this algorithm is presented ... -
Optimisation of deep burn incineration of reactor waste plutonium ina PBMR DPP-400 core
Serfontein, Dawid E.; Mulder, Eben J.; Reitsma, Frederik (Elsevier, 2014)In this article an original set of coupled neutronics and thermo-hydraulic simulation results for the VSOP 99/05 diffusion code are presented for advanced fuel cycles for the incineration of weapons-grade plutonium, ... -
Thorium-based fuel cycles: reassessment of fuel economics andproliferation risk
Serfontein, Dawid E.; Mulder, Eben J. (Elsevier, 2014)At current consumption and current prices, the proven reserves for natural uranium will last only about 100 years. However, the more abundant thorium, burned in breeder reactors, such as large High Temperature Gas-Cooled ...
