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.

Nuclear new build procurement considerations
It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

According to the development trend of the international neutral beam injector diagnostic technology, it is planned to design a multichannel Langmuir electrostatic probe diagnostic system for the Comprehensive Research Facility for Fusion Technology negative-ion-based beam injector prototype. The probes are installed at different components of the neutral beam device to obtain plasma parameters. As the probes are at different positions and different potentials, conventional data acquisition systems, which are based on the traditional Ethernet protocol in publicly available resources, cannot meet the requirements of potential isolation and synchronous acquisition with high time resolution in the experiment. A data acquisition and processing system that is based on the fiber optic network of the Time Sensitive Networking protocol is put forward that solves the synchronous acquisition of signals at different potentials with high time resolution to achieve data processing. It provides the technical means for the study of plasma characteristics of the radio frequency negative ion source.
