Abstract

Abstract

Plate-shaped PWRs have good application prospects in long-life reactors. According to the needs of long-life plate-shaped PWRs, the four burnable poisons with better neutronics performance (¹⁵⁷Gd₂O₃, ¹⁶⁷Er₂O₃, ²³¹Pa₂O₃ and PACS-J) were studied on the selection of burnable poison loading forms, and the loading form with better neutronics performance was screened out. The results show that: Different loading forms for different burnable poisons can better meet the comprehensive requirements of long-life plate-shaped PWRs; For burnable poison with better neutronics performance, ¹⁵⁷Gd₂O₃ and ¹⁶⁷Er₂O₃ can be loaded with fuel evenly mixed; ²³¹Pa₂O₃can be loaded with burnable poison mixed in the cladding; PACS-J can be loaded in pellet form mixed with fuel.
