Abstract

Abstract

The supercritical water-cooled demonostration reactor CSR150 uses the reactivity control technology in CSR1000 for reference: reactivity control is realized through burnable poisons and control rods. Based on the selection of erbium oxide as burnable poison, this paper puts forward a design method of ¹⁶⁷Er enrichment to reduce the reactivity penalty caused by erbium oxide at EOL. The control rod design of CSR150 is studied, and the zoning design of the control rod is proposed. Boron enrichment is used as the safety rod material to improve the reactivity control ability. The evaluation results of key parameters of the core show that the proposed reactivity control scheme meets the design requirements of CSR150.
