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.”

Mitsubishi Heavy Industries Ltd, has developed a computer-aided decision making supporting panel system to support operation and management staff decision making of nuclear power plants by presenting associated information (e.g., plant situation, on-site/offsite conditions) in organized and timely manner during emergency conditions, called “DMP”. The DMP shall be located on site as well as at operation management office at off site, and present associated information for operation staff and managers at both sites to share the information and promote their communications. The DMP has been developed considering lessons learned of Fukushima Daiichi event, including situation awareness distraction and workload issues under severe accident conditions. It has been recognized that it was difficult to collect, organize and analyze plant data and associated information under high-stress conditions and severely degraded work environment. The DMP collects plant status information using plant chronological data logs, and, by manually input, associated information, such as pictures presenting site situations (e.g., various information showing damaged equipment/power cables & cabinets, and hazard area, etc.,), verbal/written status report/communication logs between operation and surveillance staff at local site. The DMP had been applied a human centered design approach by specific information display designs to comply with those International and Japanese HFE design guide (i.e., IEC 60964 and JEAG 4617) and had verified with HFE design verification and functional verification (task support verification) to ensure the DMP design meets design requirement and criteria as well as user’s needs. The DMP is workable to organize, analyze and present the current situations and recommendations to operation staff and management by collected data and policies/rules, including emergency management plans etc, which has also stored as database.
