PhD Topic: Applying Approximate Bayesian Computation to reduce nuclear data uncertainties
Supervisor: Prof. Tomasz Kozłowski
The multiplication factor (keff) is a key parameter describing the dynamics of nuclear reactors. The uncertainty in its calculated value mostly originates from the imprecision with which neutron cross sections are known and is currently relatively large in simulations of any critical systems. In the last two decades, great advances have been made in regards to computational powers and Bayesian inference algorithms. The aim of this PhD is to use these advances, along with results of documented criticality experiments, to decrease the uncertainty in chosen neutron cross section values. This will in turn increase the precision with which keff is calculated, leading to the possibility of creating more robust nuclear reactor designs.
