CANDU-BLW experiments in ZED-2. Part II: booster rod experiments
Description
Experiments have been performed in a simulated CANDU-BLW lattice in ZED-2 to determine the perturbing effect of a mockup BLW booster rod on the surrounding lattice, the neutron density distribution within the booster and its reactivity effect. Experiments were performed with the booster vertical along the axis of the lattice, and horizontal across a diameter of the lattice near the position of maximum axial flux. The maximum observed neutron density perturbation was ~ + 55% at a distance ~20 cm from the booster. Reactivity measurements in terms of changes in lattice critical height were made relative to a standard absorber. Simplified perturbation theory calculations were performed to compare with the measured relative reactivity effects. (author)
