PRAEProliferation Resistance Analysis and Evaluation Tool for Observed Risk (PRAETOR)Methodology Development

computer code, named PRAETOR (Proliferation Resistance Analysis and Evaluation Tool for Observed Risk), has been developed to aid in comparing the proliferation resistance (PR) of nuclear installations. The well-established decision analysis methodology called Multi-Attribute Utility Analysis (MAUA) is the backbone of the code and the code is developed using the Fortran 90 programing language. The PRAETOR code employs attributes, which considers both intrinsic and extrinsic measures at a nuclear installation that inhibit special nuclear material (SNM) proliferation. Currently, PRAETOR uses sixtythree attribute inputs to capture the PR characteristics of the SNM and the nuclear installation being analyzed. The PRAETOR code derives a single metric for PR performance comparison by appropriately folding the sixty-three inputs using their respective weights (relative importance) and the MAUA methodology. Two nuclear material diversion scenarios for a nuclear fuel cycle installation are shown to give reasonable insights into the facility PR characteristic for decision making.
