GEH and GE Digital have introduced Outage Planning and Analytics (OPA), a digital solution to help nuclear power plant operators plan, schedule and execute maintenance and refueling outages. 

Using comprehensive data, analytics and tools, cross-functional teams can build optimal programs that execute on time. The OPA solution is built on GE Digital’s Predix Platform and is currently available to U.S. operators of both boiling water reactors (BWRs) and pressurized water reactors (PWRs). GE continues to enhance OPA to meet the needs of customers in the nuclear energy industry as well as offering the product to customers in other industries. 

OPA’s planning features are designed to help plant operators assess outage readiness and can be used at the beginning of the outage planning cycle. Scheduling analytics are used in advance of an outage to identify potential schedule risk and actions to optimize scheduling. OPA is also designed to be used during the execution of outages to monitor task performance using advanced analytics to improve decision making. The solution is deployed in an export control compliant platform.

OPA can potentially save plant operators millions of dollars per outage by enabling them to create the best plan and execute on time.

Unique Analytics and Intelligence  

OPA features unique purpose-built analytics and intelligence tools tailored to outage management. 

Go Codes and Impact Score Analytic: Go Coded Activities are activities whose predecessors have all been completed ready to be picked up and worked. Which activities have the highest impact down stream and by choosing to work on them find the best path.

Bow Wave Analytic: Historical data from dozens of outages to track and to predict ahead/behind trends for both activities and worker hours. The workdowns track the scheduled, open, and emergent work remaining in the schedule daily.

Delay Category Analytic: Analyzes completed activities to discover production inefficiencies by day and by discipline driving accountability. An activity’s delay category is determined using schedule properties.

Window Threat Analytic: Analyzes groups of activities, usually associated with taking a system or window out of service, to determine if any sequence is becoming a threat to the schedule. If a window’s activities are late or lose total float or if emergent work is added to the window, the threat increases.
