Uncertainty Analysis Tool for the Performance Assessment of the High Level Radioactive Waste Disposal System

The uncertainty analysis is one approach to indicate long-term safety of a HLW disposal system. Usually it is very difficult to construct the computer code for uncertainty analysis by using individual process existing computer codes without revising source program in a short time. Because detailed modification for an uncertainty analytical function and a post-processing procedure is needed in each computer code. We have developed the uncertainty analysis tool, which can apply to any computer codes. This uncertainty analysis tool is very effective to calculate the efficiency and quality for linkage of existing individual process computer codes.
