“…Wyss et al [12] developed a riskbased approach for safeguards and security decision-making that provides additional data to consider adversary activities before an attack. Several other efforts address integration of adversary activities to determine a wider range of threats beyond a design basis [13,14,15]; to develop an uncertainty risk analysis (URA) [16,17,18,19] technique to evaluate the risks of intentional acts; and to provide total risk assessment capability (TRAC) that addresses adversary threat, vulnerability and consequence [20].…”

Next generation nuclear fuel cycle facilities will face strict requirements on security and safeguards of nuclear material. These requirements can result in expensive facilities. The purpose of this project was to investigate how to incorporate safeguards and security into one plant monitoring system early in the design process to take better advantage of all plant process data, to improve confidence in the operation of the plant, and to optimize costs. An existing reprocessing plant materials accountancy model was examined for use in evaluating integration of safeguards (both domestic and international) and security. International safeguards require independent, secure, and authenticated measurements for materials accountability-it may be best to design stand-alone systems in addition to domestic safeguards instrumentation to minimize impact on operations. In some cases, joint-use equipment may be appropriate. Existing domestic materials accountancy instrumentation can be used in conjunction with other monitoring equipment for plant security as well as through the use of material assurance indicators, a new metric for material control that is under development. Future efforts will take the results of this work to demonstrate integration on the reprocessing plant model.

“…LinguisticBelief, a computer tool that has been under development at Sandia National Laboratories, is designed to analyze combinations of linguistic variables in which there is significant vagueness (Darby, 2007). The belief/plausibility measure of uncertainty is used to capture and propagate uncertainty for the linguistic variables.…”

Asymmetric threats are the new face of security in the 21st century, where a new breed of adversary threatens long established, essentially monolithic institutions at the core of western civilization. The direction of technology development has the potential to further exacerbate the unbalanced standoff between the new threat and established institutions, whether government, commercial, industrial or cultural, particularly when the adversary is a determined and ideologically driven foe that is willing to bide their time and develop their resources over extended periods that may stretch into decades. Systems Engineering has the potential of offering security solutions that look beyond the traditional approach of adding layers of security to functional systems. Security that is inherent to the product or process may be more adept at addressing the dynamic threat environments of today. The restructuring of organizational and product architectures may “rebalance” the threat/risk equation and reduce potentially catastrophic asymmetric threats to a tolerable symmetric “standoff.” Such restructuring does not come about easily or quickly, however, and fundamental shifts in infrastructure and culture can require generations to fully implement, so research into new security concepts today may not be completely realized until the 22nd century.

“…[Darby 2006 and2007] For the purposes of this report, the following summary information is provided. When we use linguistics (words) to classify events the words have a type of uncertainty called "vagueness."…”

“…Certainty is a case where the probability is 1.0 for one fuzzy set. [Darby 2006 and2007] The bottom graph in Figure 4-2 is the complementary cumulative belief/plausibility function for "Risk Level," or the "likelihood" of exceedance of a fuzzy set for "Risk Level." The likelihood that "Risk Level" is greater than "Discretionary" is 1.0, the likelihood that "Risk Level" is greater than "Emerging Concern" is 1.0, and the likelihood that "Risk Level" is greater than "High" is 0.0 since we are certain that the risk for this scenario is "High."…”

In 2005, a group of international decision makers developed a manual process for evaluating terrorist scenarios. That process has been implemented in the approximate reasoning Java software tool, LinguisticBelief, released in FY2007. One purpose of this report is to show the flexibility of the LinguisticBelief tool to automate a custom model developed by others. LinguisticBelief evaluates combinations of linguistic variables using an approximate reasoning rule base. Each variable is comprised of fuzzy sets, and a rule base describes the reasoning on combinations of variables' fuzzy sets. Uncertainty is considered and propagated through the rule base using the belief/plausibility measure. This report documents the evaluation and rank-ordering of several example terrorist scenarios for the existing process implemented in our software. LinguisticBelief captures and propagates uncertainty and allows easy development of an expanded, more detailed evaluation, neither of which is feasible using a manual evaluation process. In conclusion, the Linguistic-Belief tool is able to 1) automate an expertgenerated reasoning process for the evaluation of the risk of terrorist scenarios, including uncertainty, and 2) quickly evaluate and rank-order scenarios of concern using that process.
