Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

To both maintain safety of nuclear plants and bolster economic competitiveness, it is crucial to understand how to optimize the control and monitoring tasks that nuclear operators perform in the main control room. The concept of a computerized operator support system (COSS) that monitors the plant, performs prognostic analysis to detect anomalies, and then alerts the operator to those anomalies, is one approach that provides promise for bolstering performance and ultimately allowing the operator to keep the plant running for maximum efficiency. The COSS concept leverages a number of technologies to realize these potential performance benefits including computer-based procedures (CBPs), prognostic algorithms, and the displays to convey the system states. The displays for a COSS are the focus of this paper. A prototype tool for building overview screens was developed and evaluated to advance COSS capabilities beyond static displays. The tool is called the Graphical Augmentation Interface for Yoked Overviews (GAIYO, after the Japanese word for “overview”), and is built on the Advanced Nuclear Interface Modeling Environment (ANIME) framework. ANIME-GAIYO automatically generates overview screens that are linked to the CBP system, a type of task based display that tracks the current procedure step and aggregates the information from disparate board controls required for that procedure step into one convenient and easily monitored location. The CBP system dynamically updates the indicators presented for each step such that the operators can reliably reference it to quickly ascertain the plant status. It is purely informative and does not feature controls. Therefore, it represents a technology that could be more readily adopted than the full-fledged COSS concept, which would require a significant regulatory approval process. The evaluation is ongoing, but initial results suggest the tool is advantageous as an operator aid. In particular, the tool provides a strong benefit to allow operators to quickly identify the state of the plant for the current procedure step and then drill down into the control boards with good situation awareness to verify the state based on their initial estimate. Ultimately, this tool provides additional evidence for pursuing the COSS concept and realizing the benefits of a system on operator performance.
