Alert

Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

Use of Physical Protection Modeling and Simulation (ModSim) Tools to Optimize Security Plans

Sponsored by the Office of Nuclear Security and Incident Response

This digital exhibit will discuss the use of computer-based ModSim tools to support physical security planning at commercial nuclear facilities, as well as the steps the NRC is taking to prepare licensing and inspection staff to conduct reviews of licensees' use of these tools. Existing licensees at operating facilities are already using such tools to enhance their facility security plans. This topic is expected to become even more important as NRC staff anticipate that advanced reactor applicants will rely more heavily on results from ModSim tools to support proposed security plans for new facilities.
