“…This means that Green's functions were valid, hence, the proposed methodology that employs the integrated FE model and its transfer functions is applicable. To measure the aging status, a prototype of the expert system for the integrity evaluation of NPPs, called the aging monitor, was suggested and developed in the authors' previous studies [12,13]. This system consists of 5 modules such as an aging alarm/ coloring monitor, an aging database, an aging document, a real-time integrity monitor and a surveillance and inspection management system.…”

“…However, the study of the Fukushima accident has shown that the agreement of simulation results with NCEP data is better than that with ECMWF data [147]. The detection data prepare the groundwork for subsequent aging monitoring systems [148], situation awareness [149], and fault diagnosis [150].…”

Emergency decision support techniques play an important role in complex and safety-critical systems such as nuclear power plants (NPPs). Emergency decision-making is not a single method but a framework comprising a combination of various technologies. This paper presents a review of various methods for emergency decision support systems in NPPs. We first discuss the theoretical foundations of nuclear power plant emergency decision support technologies. Based on this exposition, the key technologies of emergency decision support systems in NPPs are presented, including training operators in emergency management, risk assessment, fault detection and diagnosis, multi-criteria decision support, and accident consequence assessment. The principles, application, and comparative analysis of these methods are systematically described. Additionally, we present an overview of emergency decision support systems in NPPs across different countries and feature profiles of prominent systems like the Real-Time Online Decision Support System for Nuclear Emergencies (RODOS), the Accident Reporting and Guiding Operational System (ARGOS), and the Decision Support Tool for Severe Accidents (Severa). Then, the existing challenges and issues in this field are summarized, including the need for better integration of risk assessment, methods to enhance education and training, the acceleration of simulation calculations, the application of large language models, and international cooperation. Finally, we propose a new decision support system that integrates Level 1, 2, and 3 probabilistic safety assessment for emergency management in NPPs.

“…Various types of aging monitors linked with the virtual plant were suggested to manage a nuclear power plant [4]. In these management systems, monitoring and delivery of information, which includes geometry, related documents, and degradation mechanisms, were strengthened by the adoption of the virtual plant and the associated database.…”

The present paper aims to suggest a web-based LNG (Liquefied natural gas) plant management system that is applicable from the design stage through the operational lifetime of the plant. The usefulness of this program is maximized by combining a virtual plant and RAMS (Reliability, availability, maintainability and safety). To achieve this goal, principles related to a virtual plant and RAMS are reviewed and several modules were designed. In particular, the RBI (Risk based inspection) module based on the API (American Petroleum Institute) code was developed for implementing RAMS. To review the design and deliver geometrical information regarding the system and processes, several commercial softwares are chosen to develop the navigator module and virtual module of LPMS-RAMS (LNG Plant Management System based on RAMS). Also, several modules related to maintenance and safety, are developed. It means that the LPMS-RAMS has many applicable modules based on the concept of virtual plant and RAMS. Especially, The VR (Virtual reality) module in this system will be useful during the design stage for diverse types of LNG plants. Also, the RAMS module is expected to improve the efficiency and safety of the LNG plant during its operation.
