The Global Nuclear Detection Architecture (GNDA) is described as a worldwide network of sensors, telecommunications, and personnel, with the supporting information exchanges, programs, and protocols that serve to detect, analyze, and report on nuclear and radiological materials that are out of regulatory control. The Domestic Nuclear Detection Office (DNDO), an office within the Department of Homeland Security (DHS), coordinates the development of the GNDA with its federal partners. Performance Metrics for the Global Nuclear Detection Architecture considers how to develop performance measures and quantitative metrics that can be used to evaluate the overall effectiveness and report on progress toward meeting the goals of the GNDA. According to this report, two critical components are needed to evaluate the effectiveness of the GNDA: a new strategic plan with outcome-based metrics and an analysis framework to enable assessment of outcome-based metrics. The GNDA is a complex system of systems meant to deter and detect attempts to unlawfully transport radiological or nuclear material. The recommendations of Performance Metrics for the Performance Metrics for the Global Nuclear Detection Architecture may be used to improve the GNDA strategic plan and the reporting of progress toward meeting its goals during subsequent review cycles.

The Global Nuclear Detection Architecture (GNDA) is a multi-layered system of detection technol., programs, and guidelines designed to enhance the nation¿s ability to detect and prevent a radiological or nuclear attack. Among its components are existing programs in nuclear detection operated by other fed. agencies and new programs put into place by the Domestic Nuclear Detection Office (DNDO).

Most programs are within the Nuclear Regulatory Commission; the Departments of Defense, Energy, and State; and agencies that became part of the Department of Homeland Security (DHS) upon its creation, and they are focused on detecting the illicit acquisition and shipment of nuclear and radiological materials and protecting and securing nuclear weapons. [...] Among these responsibilities is to develop, with the approval of the Secretary and in coordination with the Attorney General, the Secretary of State, the Secretary of Defense, and the Secretary of Energy, an enhanced global nuclear detection architecture with implementation under which (A) the Office will be responsible for the implementation of the domestic portion of the global architecture; (B) [...] When advances in technology, new intelligence information, and other factors are considered, the effectiveness of the global nuclear detection architecture may need to be judged on active testing or "red teaming" of the architecture.34 The results of such active testing may be misleading if the testing does not conform to the threat for which the architecture is designed. [...] According to the DNDO, the analysis methodology underpinning the global nuclear detection architecture continues to undergo revision and refinement: In order to maximize the effectiveness of the FY 2008 edition of the [global nuclear detection architecture], DNDO will leverage the independent observation of a full peer 37 Domestic Nuclear Detection Office, Department of Homeland Security, Congress [...] The SAFE Port Act authorizes the DHS Secretary to "request that the Secretary of Defense, the Secretary of Energy, the Secretary of State, the Attorney General, the Nuclear 41 Domestic Nuclear Detection Office, Department of Homeland Security, Congressional Justification FY2008, p.

Annotation. The Global Nuclear Detection Architecture (GNDA) is described as a worldwide network of sensors, telecommunications, and personnel, with the supporting information exchanges, programs, and protocols that serve to detect, analyze, and report on nuclear and radiological materials that are out of regulatory control. The Domestic Nuclear Detection Office (DNDO), an office within the Department of Homeland Security (DHS), coordinates the development of the GNDA with its federal partners. "Performance Metrics for the Global Nuclear Detection Architecture" considers how to develop performance measures and quantitative metrics that can be used to evaluate the overall effectiveness and report on progress toward meeting the goals of the GNDA. According to this report, two critical components are needed to evaluate the effectiveness of the GNDA: a new strategic plan with outcome-based metrics and an analysis framework to enable assessment of outcome-based metrics. The GNDA is a complex system of systems meant to deter and detect attempts to unlawfully transport radiological or nuclear material. The recommendations of Performance Metrics for the "Performance Metrics for the Global Nuclear Detection Architecture" may be used to improve the GNDA strategic plan and the reporting of progress toward meeting its goals during subsequent review cycles.

In 2005, the Domestic Nuclear Detection Office (DNDO) was established to enhance and coordinate fed., state, and local efforts to combat nuclear smuggling domestically and abroad. DNDO was directed to develop, in coordination with the DoD, DoE, and the State Dept., an enhanced global nuclear detection architecture -- an integrated system of radiation detection equipment and interdiction activities. This testimony provides preliminary observations addressing: (1) the status of DNDO¿s efforts to develop a global nuclear detection architecture; (2) the challenges DNDO and other fed. agencies face in implementing the architecture; and (3) the costs of the programs that constitute the architecture. Includes recommendations. Charts and tables.

In April 2005, a Presidential Directive established the Domestic Nuclear Detection Office (DNDO) within the Department of Homeland Security to enhance and coordinate federal, state and local efforts to combat nuclear smuggling domestically and abroad. DNDO was directed to develop, in coordination with the departments of Defense, Energy, and State, an enhanced global nuclear detection architecture -- an integrated system of radiation detection equipment and interdiction activities. DNDO implements the domestic portion of the architecture while DOD, DOE and State are responsible for related programs outside the U.S. This testimony provides preliminary observations based on ongoing work addressing 1) the status of DNDO's efforts to develop a global nuclear detection architecture, 2) the challenges DNDO and other federal agencies face in implementing the architecture, and 3) the costs of the programs that constitute the architecture. This statement draws on prior GAO reviews of programs constituting the architecture, and GAO's work on strategic planning.
