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, ...
