The Research on Burnup Characteristic of Doping Burnable Posion in PWR

In PWR core design, burnable poisons are usually used for reactive compensation and power flatten. The choice of burnable poisons and how to match burnup would be the key-points for a long-life core design. We study the burnup character of doping burnable poisons（such as natural element, manual nuclide and soluble boron） in the PWR by the core burnup code MOI based on Monte Carlo method. The results show that Hf、Er and Eu doping burnable poison would be applicable for the nuclear design research on the long-life PWR core.
