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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

A remote control system to operate a manipulator arm by the HAL (Hybrid Assistive Limb) robot suit is examined in the application of in-cell equipment maintenance. In this integrated system the operator wears the exoskeletal-structured HAL and the operator's movement is transferred through HAL's computer system to a slave-type manipulator arm. The system includes a bioelectrical signals (BES) control scheme and a position control scheme. In the former scheme, sensors attached to the skin on the operator's arms detect faint BES when the operator makes a movement. The signals are processed and analyzed by a computer to determine the operator's intention. The computer then calculates the necessary assistive power and the power units generate adequate power to each joint of the HAL suit to assist the operator. To evaluate the effectiveness and usefulness of the system, remote handling experiments were designed using mockup equipment, and the performance of remote operation conducted by the two schemes mentioned above was compared with that by the more conventional three-dimensional mouse control scheme. Of these three control schemes, the BES control scheme clearly outperformed the others in executing direct-contact tasks of in-cell equipment maintenance with small operation time and small variation.
