Recognizing the persistence of governance and management concerns, this report serves as an initial assessment of the implementation plan developed by the National Nuclear Security Administration and the Department Of Energy for addressing the recommendations from A New Foundation for the Nuclear Enterprise. There will be seven semi-annual interim reports to evaluate progress in implementing the plan. A final report will be issued at the end of the study to document the overall progress in executing the implementation plan, assess the effectiveness of the reform efforts under that plan, and recommend whether further action is needed.
