An Approach to Managing Credible Rollup to Reduce Operational Impacts

The rollup methodology presented in this paper provides a framework for managing the dynamic flow of materials between multiple facilities at a site to monitor and prevent credible rollup while meeting the changing needs of operations. This approach to rollup management reduces the operational impact by lessening the restrictions on quantities of materials needed by a facility. The approach improves effectiveness and operational efficiency. LANL has developed a set of criteria to be applied in determining the credible rollup value for the site. The total quantity of material is evaluated against the criteria to determine which portion of the total should be considered as part of credible rollup. The material exclusion principles will be presented.
