Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

The creation of large-sized magnetic islands through excitation of neoclassical tearing modes (NTMs) and the concommitant degradation of energy confinement is a major concern for ITER. The basic physical mechanisms governing the dynamics of this instability are introduced, and important experimental observations and techniques of controlling or suppressing these modes are briefly reviewed. The effects of plasma rotation on the excitation threshold and saturated island sizes of NTMs, as observed in many recent experiments, and their present understanding as obtained from model analytical and numerical simulations are discussed.
