Popis:	For the flattening of burnup reactivity in long-life prismatic High-Temperature Gas-cooled Reactors (HTGRs), the effect of particle type on burnable poison properties is analyzed in detail using Monte Carlo calculations. Some examples of optimized specifications are shown. It is shown that combinations of particles with different materials, diameters, and concentrations make it possible to reduce excess reactivity to around or below 1 $ during the core life. The use of optimized burnable poison particles will help improve the passive safety features of long-life prismatic HTGR.
