NNSA provides assistance in developing and conducting emergency drills and exercises.  Exercises provide a valuable test of emergency management systems that yields results and “lessons learned” necessary for continued improvements to emergency preparedness and response programs.  Results from drills, exercises, and evaluation programs are used to develop and improve training programs and emergency plans and procedures to ensure the effectiveness of emergency management systems.  These exercises not only demonstrate the effectiveness of plans and procedures, training and equipment and adequacy of response arrangements and resources, they also provide a method to assess capabilities of response personnel in performing their assigned tasks, the ability of individuals and organizations to work together and a forum for exploring and testing revisions, modifications, new and/or proposed changes to any emergency program element in near realistic situations.
