Use of Physical Protection Modeling and Simulation (M&S)
Tools to Optimize Security for New Reactors Lead Author: Albert Tardiff Presenter: Raj Iyengar United States Nuclear Regulatory Commission The views expressed are those of the authors and do not reflect the views of the U.S. Nuclear Regulatory Commission.

- Most nuclear reactors in the U.S. predate current physical security requirements.
- Security features needed to be incorporated after-the-fact.
- In 2008, the NRC emphasized the consideration of physical security with safety during reactor design.
- Modeling and simulation (M&S) tools have been developed to support security design.
History
- Advanced reactor vendors have begun using M&S to support the design of physical protection systems.
- M&S tools can calculate potential adversary pathways and responses to adversary actions.
- Effectiveness (PE) determined based on probability of intercepting adversaries (PI) and probability of neutralization (PN)
Modeling and Simulation
- Ability to perform many assessments quickly
- Evaluation of security features before incorporating them into reactor facility designs
- Supports consistency and efficiency in reviews of licensee submittals
- Reduced need for retrofits Advantages of M&S
M&S Elements for SMRs/Advanced Reactors Facility Characterization Pathway Analysis Combat Simulation
- Evaluates how well a protection strategy achieves its performance objectives A realistic value of PE is always less than one
- A regulatory authority can establish a value for PE for nuclear facilities to achieve Probability of System Effectiveness Calculation
