Abstract

Abstract: Natural boron is widely used for chemical compensation control of reactivity in PWR. Research shows enriched boron, as an alternative of natural boron, can optimize the primary loop hydrochemistry and therefore reduce the materials corrosion risk of primary loop structure and core deposition risk. It reduces the occupational exposure dose as well. This paper analyzes the advantages and feasibility of using enriched boron in PWR. It introduces the practical application of enriched boron in both domestic and overseas PWRs. Finally, suggestions are proposed on the application of enriched boron for HPR1000 and domestic operating PWRs.

Key words: enriched boron, hydrochemistry optimization, occupational exposure dose, HPR1000, zinc injection
