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.

Technical Paper | Sixteenth Joint Workshop on Electron Cyclotron Emission and Electron Cyclotron Resonance Heating (EC-16) | doi.org/10.13182/FST11-A11726

A program of electron cyclotron heating (ECH) with 4 MW at 140 GHz has been launched for developing scenarios of stable high performance through control of the pressure and current density profiles on the EAST tokamak. Several electron cyclotron emission (ECE) diagnostics are under development as important components of the research program on EAST. The smaller HT-7 tokamak is equipped with a multichannel superheterodyne radiometer and an ECE imaging system. Physics issues including fluctuations driven by electron and ion modes, low frequency zonal flows, magnetic reconnection mechanisms, etc. were investigated on HT-7 using these two systems, which have been moved to EAST after some modifications. New systems, including a 32-channel ECE system and an ECE imaging system of 24(radial) × 16(vertical) channels, are under development. These new systems are designed for the ECH plasma regimes and provide long-range correlation measurements of plasma turbulence. A grating polychromator ECE system has been installed for measurement of the Te profile covering the whole operational range of toroidal magnetic field on EAST.
