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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Data-driven online monitoring of nuclear power plants aims to improve the economic viability of the plants by reducing the cost of operations and maintenance (O&M) activities. This can be accomplished by reducing the labor hours, frequency of activities, materials, and support activities needed. A technology roadmap to migrate plants from a manual inspection process to a data-driven online monitoring process is a systematic guideline to prioritize resource utilization and the amount and/or type of data collected, while taking advantage of improved analytical and visualization techniques to extract better insights from the data. This process maximizes the value of the migration to a data-driven approach, and tackles various change management challenges to the deployment of online monitoring methods. Without an end-state vision and migration plan, plants risk wasting resources by implementing multiple incremental system upgrades as each new technology or process is incorporated. This paper presents a summary of the migration process for each of six elements required to fully or partially automate manual processes in nuclear power plants. These elements are data collection, data management, data analytics, data visualization, value analysis, and change management.
