In particular, measures to minimize the void reactivity effect were considered, including reduced core dimensions or abandoned lateral and axial blankets, reduced fractions of the structural materials and coolant in the core and a decrease in the effective coolant density. Use of the gas lift system to reduce the effective coolant density was found to be one of the most promising approaches to enhance reactor safety and improve economics.
