Research on Risk Management of Nuclear Engineering - Taking T Project Reverse Power Supply As an Example

Under the vision of sustainable development and a community with a shared future for mankind, the era of “zero carbon” is coming to us. Nuclear energy has long been seen as one of the powerful means to achieve a “carbon neutral” future. Nuclear power projects are characterized by high technical requirements, long construction period, complex system composition, numerous stakeholders and heavy social responsibilities. Any link is crucial. Therefore, effective risk management of nuclear power projects is of great significance. Based on the actual situation of nuclear POWER T project, the following studies are carried out: (1) Through the research of domestic and foreign literature, Delphi method anonymous voting and expert consultation meeting were adopted to merge, filter and supplement the risk factors, and 24 risk factors in seven categories, including design, installation and commissioning, construction, contract, external, procurement and administrative licensing, were identified in the process of power transmission of NUCLEAR POWER T project. (2) AHP fuzzy comprehensive evaluation method is used to select the hierarchical structure model of power supply risk factors, construct a judgment matrix, establish a risk evaluation table, calculate the risk weight of each level and rank it, compare the value interval of risk evaluation set, and get the power supply risk level of NUCLEAR power T project. (3) In the outlook, the author considers the use of bow-tie model to prevent and control risk events in advance in the future, so as to formulate measures. Finally, the integrated risk control platform of reporting, early-warning, disposal and monitoring is proposed to form a closed-loop management of risk identification, reporting, disposal and rectification.
