In support of the future decommissioning of the TRIGA reactor Vienna an inventory of expected radioactive structural materials turned up several holes in the locally available data. The following work attempts to close one of the two major ones with a mix of simulations and measurements of similar material because the real structures are not directly accessible. The concrete floor below the reactor pool is calculated by an extension of the MCNP reactor model, which is validated by flux measurements at the reactor pool bottom. This results in an additional 0.63 m³ radioactive and 2.2 m³ restricted release heavy concrete waste to 4.3 and 8.6 m³ from the biological shield.
