(iii) Sensitivity and uncertainty calculations of the effective delayed neutron fraction ([[beta].sub.eff]) [28-30].
The effective delayed neutron fraction is a key reactor safety parameter involved in the control rods worth calculations and transient (reactivity feedback effect) studies.
The measurements were performed on critical eigenvalue ([k.sub.eff]), and material buckling, reaction rate ratios, material worth, fission rate, and capture rate distributions as well as effective delayed neutron fraction [[beta].sub.eff] were measured.
In the scope of the CHANDA project of the European Commission a sensitivity and uncertainty analysis of the neutron multiplication factor [k.sub.eff] and the effective delayed neutron fraction [[beta].sub.eff] was performed to identify the most important nuclear data for neutron-induced reactions for criticality calculations of the latest MYRRHA designs.
