Force-on-Force (FOF)

Inspections designed to evaluate and improve the effectiveness of a licensee's security force and ability to defend a nuclear power plant and other nuclear facilities against a design-basis threat. An essential part of the security program instituted by the NRC, a full force-on-force inspection spans 2 weeks and includes tabletop drills and multiple simulated combat exercises between a mock commando-type adversary force and the plant's security force. For further detail, see Backgrounder on Force-on-Force Exercises at Nuclear Power Plants and Protecting Our Nation.
