“…The reactivity coefficients relates the change in thermal-hydraulics conditions to the core neutronics through changes in reactivity. As indicated by some previous works, as [A. Pavlovitchev et al 2001], MOX fuel results in a slightly larger Doppler coefficient and a significantly larger moderator temperature coefficient. This condition can be a concern in accident scenarios characterized by an overcooling of the core.…”
