Nuclear Safety and Security / Radiological Emergency Preparedness

Expert Analysis and Planning Support for Improved Plant Safety and Preparedness

Global demand for nuclear energy is rapidly increasing. Even by conservative estimates, worldwide nuclear capacity is expected to increase five-fold over the next 50 years. As new reactors are brought online in the post 9/11 environment, the need to ensure nuclear safety, security, and preparedness for radiological emergencies becomes paramount.

IEM’s expertise in nuclear safety and security can help ensure that the 21st century’s nuclear renaissance unfolds in a safe and sustainable manner. We support federal, state, and local government agencies, licensees, and the Nuclear Energy Institute (NEI) in improving preparedness for radiological emergencies, developing and exercising programs and policies to best protect communities while ensuring safe and secure operations. IEM works with licensees to develop their operational and new plant licensing [Early Site Permits (ESP) and Combined Operating License Applications (COLA)]. We are an active member of the Nuclear Energy Institute—the industry’s policy organization, supporting analyses of proposed Nuclear Regulatory Commission (NRC) rule-makings and ready to assist in navigating and complying with new regulations.

IEM has more than three decades of experience helping government, industry, and the public ensure protection from both human-caused and natural hazards. We have supported FEMA’s Technological Hazards Division since 1993 and partnered with the Department of Homeland Security’s Chemical and Nuclear Preparedness and Protection Division to evaluate emergency preparedness capabilities for critical infrastructure. For over 10 years, IEM has provided emergency preparedness support for domestic and international nuclear licensees, including five of the largest U.S. nuclear power companies, which together manage over 25 percent of the operating nuclear power plants.

IEM also has a 29-year history working with state and local governments to improve safety and security. We have developed long-term, trusting relationships with these organizations and are known as an “honest broker” among them. These governments play a vital role in community preparedness for radiological emergencies. They are essential to nuclear safety and security and a sustainable future for the nuclear industry.


Radiological Emergency Preparedness – IEM provides support in all areas that ensure that a nuclear facility is prepared for an emergency, including emergency plan development, Evacuation Time Estimate studies, public outreach, coordination with and readiness assessments of off-site response organizations, and planning for hostile action-based events.

Nuclear Security – Our nuclear security services include security plan development and reviews, physical security assessments, vulnerability assessments, evaluation of existing and proposed nuclear security strategies using 3-D visualizations, and nuclear security training using serious gaming technology.

Licensing Support – IEM offers comprehensive engineering and project management support for development and submission of operating and new plant licenses. Our services include engineering, economic, environmental, and sociological analyses; emergency plan development and reviews (including web-based tools for automated plan development); Evacuation Time Estimates; and information management.

Training and Exercises – IEM’s HSEEP-compliant services include exercise program development, exercise evaluation, exercise scenario development (using multimedia tools that include 3-D models), tabletop and full-scale exercises, hostile action-based drills, NIMS/ICS training, customized training program development, and train-the-trainer programs.

Information Technology – IEM’s technology expertise can be applied to custom software development, dispersion models, consequence assessment tools, systems integration, Emergency Operations Center (EOC) design (including virtual EOCs), intranet/portal development, and cybersecurity.

Demonstrated Successes

IEM was a pioneer in developing and implementing the concept of “balanced response”—a risk-based protective action strategy that involves a combination of shelter-in-place and evacuation for maximum public protection. And, we’re considered national experts in evacuation modeling, having conducted more than 20 technological hazard studies.
