摘要

The behavior of a disposal system site with hazardous and radioactive wastes is quantitatively evaluated in a risk assessment using the risk metrics of peak-of-the-mean, mean-of-the-peaks, and cumulative release. These metrics are commonly used to estimate risk and demonstrate compliance allowing the site to obtain an operating license. Compliance may be determined according to satisfying a regulatory standard that includes a time period of interest such as a compliance period. This paper evaluates the effect of the compliance period on risk metrics of peak-of-the-mean, mean-of-the-peaks, and cumulative release using a simplified model. The model includes the following parameters: waste container failure, release from a disposal site, and transport of the release with retardation to a receptor. Monte Carlo sampling is used to investigate the impacts of uncertainty on the risk predictions. The sampling accounts for uncertainty within the disposal system and utilizes probability distribution functions for the modeled parameters. Risk predictions are determined for a range of compliance periods and the effect of the compliance period on these performance assessment risk metrics is quantitatively demonstrated. The results are normalized with respect to a containment time that is characterized as spanning conditions from poorly contained to well-contained. The results from the analysis indicate that the compliance period should be greater than the containment time for the disposal system Risk predictions for each metric are stable and accurate when the compliance period is greater than the containment time for the disposal system. If the compliance period is less than the containment period, risk predictions using these metrics can be unstable and inaccurate.
