National Nuclear Security Administration Has Improved the Security of Reactors in Its Global Research Reactor Program, but Action Is Needed to Address Remaining Concerns : Report to the Chairman, Subcommittee on National Security and Foreign Affairs, Committee on Oversight and Government Reform, House of Representatives
Website or Online Data
Worldwide, about 165 research reactors use highly enriched uranium (HEU) fuel. Because HEU can also be used in nuclear weapons, the National Nuclear Security Administration (NNSA) established the Global Research Reactor Security (GRRS) program to make security upgrades at foreign research reactors whose security did not meet guidelines established by the International Atomic Energy Agency (IAEA). GAO was asked to assess (1) the status of NNSA's efforts to secure foreign research reactors, (2) the extent to which selected foreign research reactors with NNSA security upgrades meet IAEA's security guidelines, and (3) the extent to which NNSA coordinates the GRRS program with other countries and the IAEA. GAO reviewed NNSA and IAEA documents and visited five of the 22 research reactors in the GRRS program, which were selected on the basis of when upgrades had been completed and because the reactors still possess HEU. GAO is making recommendations to help NNSA improve security procedures and encourage the development of national security laws and regulations in countries with HEU-fueled research reactors.
