By mid-September, P5+1 diplomats (from the United States, Britain, France, China, Russia, and Germany) will likely resume talks aimed at resolving concerns about Iran's nuclear program with President Hassan Rouhani's new negotiating team. The talks represent an important opportunity to finally reach a deal that limits Iran's most worrisome uranium enrichment activities, obtains more extensive inspections to guard against a secret weapons program, and shows Iran a path toward phasing out international sanctions.
Threat Assessment BriefJuly 24, 2013
Preventing the production and accumulation of fissile material is an important objective of nuclear nonproliferation efforts. Unfortunately, the nuclear Nonproliferation Treaty (NPT) exempts the fuel used in naval propulsion reactors from the constraints the treaty otherwise applies to enriching uranium beyond the levels used in civilian power reactors. As the number of countries with nuclear-powered submarines expands, this exclusionposes a growing risk to achieving the nonproliferation goals of the treaty.
