A small number of reactors, most notably the CANDU reactors from Canada, are fuelled with natural uranium, which does not have to be enriched. Previous Post. Light water in the LZ compartments acts as a neutronabsorber,andthusReactorRegulatingSystem(RRS) automatically modulates zone levels by adjusting in ows for bulk and spatial neutron ux control. Accordingly, the presence of the reactivity devices in the core introduces a strong spatial heterogeneity. The joint extended Kalman filter (JEKF) can be used also for parameter estimation. The low-pressure heavy-water moderator, contained in a vessel called the calandria, provides efficient fuel utilization and permits the use of natural rather than enriched uranium. 1. Fig. Journ.
