Overview: This project will aid in determining the technical risks as well as the regulatory issues, and potential conflicts that arise with pre-closure activities. I propose to analyze how waste management system performance is enabled or impeded by various design and operational assumptions. These include the various mix of casks received, types of waste packages used, waste acceptance and handling criteria, transportation logistics, thermal loading assumptions and surface facility design. By running a variety of simulations across various design and operational scenarios, results can be evaluated subject to defined system objectives and constraints (e.g., cost, safety risk, efficiency).

Scope and Objectives: A top-down approach is proposed to enable both a holistic assessment of total system performance as well as more detailed component analyses important to risk. Preliminary analyses will identify specific design and operational scenarios that warrant more detailed investigation. Subsequent analyses will focus on refining these scenarios, including exploring opportunities to achieve improved system performance based on specified system objectives and constraints.
