Description

Physics experiments were performed on the SM-1 core. Measurements were made on five rod bank positions and rod calibrations. The reactivity effects of core modifications were investigated. Modifications to the core included replacement of the boron absorbers in rods 1, 2, 3, 4 and C with europium absorbers; replacement of a control rod fuel element with one containing an integral europium flux suppressor; and replacement of a stationary fuel element. Additional experiments were designed to determine the reactivity of the SM-1 with 4 and 8 stationary elements removed; the neutron flux in the biological shield and in the region of … continued below
