| Abstract: | The KBS-3 canister for geological disposal of spent nuclear fuel in Sweden consists of a ductile cast iron insert and a copper shielding.The ductile cast iron insert provides the mechanical strength whereas the copper protects the canister from corrosion.The canister inserts material were referred to as I24,I25 and I26,Spent nuclear fuel make the repository in high radiant intensity.The radiation analysis of canister insert is important in canister transport,the dose analysis of repository and groundwater radiolysis.Groundwater radiolysis,which produces oxidants(H2O2 and O2),will break the deep repository for spent nuclear fuel.The neutron dose distribution of canister surface with different kinds of canister inserts(I24,I25and I26) is calculated by MCNP.Analysing the calculation results,we offer a referrence for selecting canister inserts material. |
