This grant supports activities in support of the American Academy of Arts and Sciences' (AAAS) Global Nuclear Future Initiative, an international effort that focuses on increasing the security of nuclear materials, strengthening the global nuclear regime, and solving the unresolved problem of what to do with spent nuclear reactor fuel. Led by Stephen Miller, Director of Harvard University's International Security Program, the project aims to build international consensus around a series of prescriptions for strengthening nuclear security, including principles governing the development of regional nuclear storage facilities; best practices governing contracts between suppliers, customers, and government entities; and the proper arrangements connecting nuclear fuel storage and disposal. Supported activities under this grant include the convening of regional meetings of key stakeholders in government, industry, and non-governmental organizations and the commissioning of conference presentations and publishable research papers by respected experts, academics, and practitioners in the field.
