ISN/CTR administers the FIRST Program which provides technical capacity-building support to potential nuclear energy newcomer countries and current nuclear energy countries that are considering SMRs and other advanced reactor designs to meet their clean energy needs, consistent with the highest international standards of nuclear security, nonproliferation, and safety. FIRST is designed to enhance U.S. bilateral and multilateral cooperation, consistent with the IAEA nuclear energy infrastructure development milestones approach, in nuclear energy infrastructure development, nuclear security, and capacity-building. In so doing, the program supports secure, safe, and proliferation-resistant deployment of SMRs or other advanced reactors to partner countries.
