“…A report published by INL in September of 2012, entitled Design to Achieve Fault Tolerance and Resilience, described the benefits of automating operator actions for transients (Quinn et al, 2012). The report identified situations where there are alternate configurations and actions that can mitigate the need for a safety actuation, such as a reactor trip, if there is time to do so.…”

A Computerized Operator Support System (COSS) is an operator assistive technology that aids operators in monitoring processes to detect off-normal conditions, diagnose plant faults, predict future plant states, recommend mitigation alternatives, and select appropriate mitigation actions. The COSS works in collaboration with an advanced prognostics system called PROAID. The COSS provides a human-machine interface to help operators maintain situation awareness and detect faults earlier than would be possible using conventional control room technologies at nuclear power plants. Here we describe a third-iteration of efforts to develop and validate the COSS. The COSS has now been implemented as a prototype system for a full-scope nuclear power plant simulator. To date, two studies involving three licensed reactor crews were conducted to evaluate the COSS. Here we capture insights into the development of COSS as well as operator feedback and future development guidance derived from the operator-in-the-loop simulator studies.
