The changes in the operating conditions of the main control room of nuclear power plants due to new digitalized human-system interfaces (HSIs) pose challenges to traditional human reliability analysis (HRA) methods. This paper reviews current knowledge about the effect of digital HSI on human behaviour and reliability, relevant performance shaping factor (PSF) taxonomies as well as research on the effect of PSFs on human error probability estimates in advanced control rooms (ACRs). It cannot be generally concluded that either analogue or digitalized control rooms would be always better than the other. ACRs have the potential to offer error reducing and supportive features to the user, but may also introduce increased complexity and interface management tasks as well as potentially error-prone team working practices. Some effects seem universal, but most depend on the specific design. The main PSF categories presented in HRA methods and international guidelines seem still relevant in ACRs. Quantitative empirical studies show that especially training and experience, availability and quality of procedures as well as task type or complexity are important factors. However, digitalization changes the way in which the PSFs should be defined and measured, and the effects of PSFs on the error estimates may be different.

“…Operators in MCRs utilize intra-team communication to manage control room responsibilities such as monitoring and task implementation activities. According to Lin, Hsieh, Yang, & Huang (2016), communication in an MCR can be defined as the different information exchanges amongst operators. The importance of team communication in assisting operators with procedural tasks has been identified in many studies in the past (Cannon-Bowers, Tannenbaum, Salas, & Volpe, 1995;Ford & Schmidt, 2000;Glickman, Zimmer, Montero, Guerette, & Campbell, 1987;Pinto & Pinto, 1991;Scholtes, 1988).…”

This research explores the design, implementation, and evaluation of a prototype augmented reality application that assists operators in performing procedural tasks in control room settings. Our prototype uses a tablet display to supplement an operator's natural view of existing control panel elements with sequences of interactive visual and attention guiding cues. An experiment, conducted using a nuclear power plant simulator, examined university students completing both standard and emergency operating procedures. The augmented reality condition was compared against two other conditionsa paper-based procedure condition using paper manuals and a computer-based procedure condition using digital procedures presented on a desktop display. The results demonstrated that the augmented reality based procedure system had benefits in terms of reduced mental workload in comparison to the other two conditions. Regarding task completion time, accuracy, and situation awareness, the augmented reality condition had no significant difference when compared against the computer-based procedure condition but performed better than the paper-based procedure condition. It was also found that the augmented reality condition resulted in fewer intra-team inquiry communication exchanges in comparison to both paper-based and computer-based conditions. The augmented reality condition, however, yielded poorer memory retention score when assessed against the other two conditions. These results improved the understanding of augmented reality assistance systems for control room operations. We also discussed the implications of this study and directions for future research.

“…CBPs have been in existence for several decades, and much human factors research has been conducted examining advantages of CBPs on control room operations and plant safety. A full-scope study found CBPs improved task monitoring awareness and higher task performance when completing emergency response procedures (Lin et al, 2016). CBP functionality can help to offload some of the complexity of procedure following (e.g., continuous monitoring of a plant parameter), leading to fewer procedure deviations and smoother transitions between procedures (Le Blanc, Oxstrand, & Joe, 2015).…”

The United States (U.S.) has 99 operating Nuclear Power Plants (NPPs). The majority of these were designed and commissioned in the 1970s and 1980s. Plants are modernizing their control systems and main control rooms to be able to continue operating past their original 40-year license agreements. U.S. NPP main control rooms are migrating towards hybrid controls with both digital and analog systems. Digital upgrades, while costly, provide improved reliability, reduced maintenance cost, and the potential for fewer unplanned outages and fewer human errors. U.S. utilities have been slow to embrace computerized procedure system (CBP) research, even though CBPs demonstrate clear operational and human factors benefits. Most of the CBP research has been oriented to new reactor designs or full digital control rooms and is not applicable to the piecemeal modernization approach favored by U.S. plants. Research is needed to examine how CBPs impact operations in hybrid control rooms, and how current paper based procedures can be efficiently migrated to computerized platforms. Work is underway to develop tools and perform the obligatory research needed to design and validate CBPs for modernized U.S. nuclear control rooms.
