Holtec stated they plan to use report PNL-7839,"Performance testing and analyses of the VSC-17 ventilated concrete cask", for the experimental data to support their benchmarking efforts. Basically, Holtec plans to develop a homogenized model of the VSC-17 for comparison to the PNL-7839 data; after obtaining model agreement with the experimental data they plan to then apply the same method in the homogenization of the 24PT1-DSC. Given one system (VSC-17) is an above-ground system and 24PT1-DSC is a below-grade system, NRC's staff suggested for Holtec, when developing their response to the RAI, to consider explaining the differences and uncertainties in the models. NRC's staff again suggested for Holtec to consider development of a detailed canister model. Holtec responded, they believe their approach will be conservative and sufficient to demonstrate the case for safety.
