Section 4. Disposal Inventory
4.1 Radionuclides
In the extended KIF there is a table showing the total inventory in BWR and PWR assemblies of 13 radionuclides (Bq) of importance for radiotoxicity and calculated long-term risk (alphabetic order). The inventories are calculated for the calendar year 2045.
4.2 Toxic components
To assess the potential chemical toxicity of the waste in the final repository, the elements in the fuel, the fuel elements and fuel boxes, the copper canister shell and the canister insert were compiled …
