“…An effective safety control design can improve plant operation economics, by optimizing safety margins to reduce unnecessary shutdown cases (O'Hara, 1994). This also takes into account human factors involved in plant operation in order to ensure that safety margins are matched with required operator actions (Moray and Huey, 1988;Lee and Seong, 2004).…”

Small and major accidents and near misses are still occurring in nuclear power plants (NPPs). Risk level has increased with the degradation of NPP equipment and instrumentation. In order to achieve NPP safety, it is important to continuously evaluate risk for all potential hazard and fault propagation scenarios and map protection layers to fault / failure / hazard propagation scenarios to be able to evaluate and verify safety level during NPP operation. There are major limitations in current real time safety verification tools, as it is mainly offline and with no integration to NPP simulation tools. The main goal of this research is to develop real time safety verification with co-simulation tool to be integrated with plant operation support systems. This includes the development of static and dynamic fault semantic network (FSN) to model possible fault propagation scenarios and the interrelationships among associated process variables. The detailed methodology involves the integration of process models, construction of static FSN with fault propagation scenarios, and evaluation and tuning of dynamic FSN with probabilistic and process variable interaction values. The focus however of the present study is to highlight the need to incorporate error reduction in performing safety verification of NPPs. Two selected case studies were used to demonstrate the proposed methodology; one on a turbine trip and the other on steam generator tube rupture. In the former case, the error reduction concept was shown while the safety verification method was demonstrated in the latter case. The results confirmed the importance of error reduction as well as the need to constantly undertake safety verification of safety critical systems such as a NPP.

“…The evaluation and verification of emergency response plan has been researched in many industries and fields, such as the chemical industry [19,21,23], the nuclear industry [5,9], the water pollution emergency [3,7], the earthquake emergency [1,4], and so on [2,8,10,[12][13][14]17]. However, most of these focus on emergency plan involving only single emergency organization, and no crossorganization collaborations are investigated.…”

“…As tools of modeling and analyzing physical systems, Petri nets [11, 15-16, 18, 25-29] have shown great power in dealing with concurrencies and conflicts. Therefore, it has been widely used to model and analyze emergency response processes [9,11,[21][22][23]. Towards the collaborative emergency management, G u o and K a p u c u [6] examined coordination in disaster response by simulation using Petri net focusing on inter-organizational process, and find some useful insights on the performance assessments.…”

Knowledge representation has been the critical and intractable issues for a knowledge-based system, especially for complex or large systems. This paper proposes a knowledge representation approach for modeling rule-based systems using the defined fuzzy colored Petri nets (FCPN). The main advantages of this approach differ from the conventional ones consist in modeling rule-based systems particularly, realizing smaller model spaces, more compact data structures and fuzzy information processing. For a large or complex rule-based system, the advantages are more evident. An instance demonstrates that the presented approach is feasible and practical.
