In unprotected loss-of-flow transients in large LMFBRs sodium voiding may result in high ramp rates of positive reactivity addition leading to rates of energy release that may exceed the design limits of the containment. Therefore, there is an incentive in designing reactors of low sodium void reactivity to reduce the positive reactivity ramp rates arising from sodium voiding. A systematic way of constructing heterogeneous configurations that have a near zero value of sodium void reactivity is presented.
