Plain-English Summary

The government would be required to study and report on the risks that nuclear power plants face if they are located in or near areas where armed conflict could occur. These reports would help lawmakers and the public understand what could happen to nuclear reactors during military conflicts and what safety measures might be needed to protect them. The information would affect nuclear facility operators, military planners, and communities living near nuclear plants in potentially vulnerable locations.
