The Computerized Operator Support System (COSS) is an operator assistive technology funded by the U.S. Department of Energy Office of Nuclear Energy and developed at Idaho National Laboratory. The project works in collaboration with an advanced prognostics system called PRO-AID developed at Argonne National Laboratory. 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. This report represents a status report outlining third-year efforts to develop and validate the COSS. The COSS has now been implemented as a prototype system, with multiple interaction design concepts on multiple plant systems in the simulator from a commercial nuclear power plant. Two studies involving three licensed reactor crews were conducted to evaluate the COSS. This report captures insights into the development of COSS as well as operator feedback and future development guidance derived from the operator-in-the-loop simulator studies.
