Validation of QAD-CGGP for Shielding Analyses of Intermediate and Low Level Waste Drums

QAD-CGGP is a three dimensional point kernel code regularly used for engineering shielding analyses. We have used QAD-CGGP to analyze shielding/storage related radiation from intermediate radioactive waste drums, regularly used at NPP Krško. A validation of the results against experimental measurements was at the moment beyond the scope of our investigation. Instead, we have compared them against results obtained in simulations of the same system using MCNP4A code. In this contribution uncollided and buildup dose rate estimates from QAD-CGGP were analyzed separately, for all important photon energy lines, and for a total source spectrum. Quantitative assessment of the accuracy of QAD-CGGP for the particular application is given.
