In this paper

boron-containing KTA-304 stainless steel for slow neutron absorption and attenuation is studied by Monte Carlo method

and compared with the traditional SUS304 stainless steel.Taking into account some factors

such as processing conditions

corrosion resistance

hot ductility

etc.we may reasonably come to the conclusion that boron content of about 1.13% in the steel has a better absorption capacity to the slow neutron and can effectively reduce the secondary γ-ray effect

meeting the request of radiation protection with reduced material thickness.Besides

slow neutron attenuation coefficient was calculated at different boron concentrations of the steel in different energies

providing a reasonable basis for selecting the neutron shielding materials.The γ-rays released in the neutron capture process were considered

too.
