ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The plasma-facing wall in the Tokamak Fusion Test Reactor (TFTR) is covered in large part by a bumper limiter. The limiter extends the full 360° toroidally and ±60° with respect to the midplane on the small-majorradius side. The limiter is the primary power-handling surface of the first wall. The heat-distribution over the two-dimensional surface of the bumper limiter during high-power neutral-beam heated discharges is determined by using a large array of thermocouples distributed around the entire limiter. The heat distribution for normal high-power neutral-beam heated discharges is not very different from that for ohmic discharges. Large variations in heat loading are found, both poloidally and toroidally, even though the limiter was aligned, at the midplane, to within 0.5 mm of a true circle. The heat distribution for discharges which exhibited carbon blooms are compared to otherwise identical discharges which did not show blooms. The heat distribution of a particularly high-power disruptive discharge is examined to determine why recovery from this discharge was difficult.
