&nbsp; &nbsp; &nbsp; &nbsp; Currently, there are still some deficiencies in the nuclear emergency drilling&nbsp;scripting and the decision-making support technology for&nbsp;emergency drilling&nbsp;in emergency headquarters, which need to be improved and perfected.&nbsp;First of all, the nuclear emergency drilling&nbsp;script is&nbsp;prepared&nbsp;mostly on the basis of&nbsp;full scope simulator or that with extended simulation&nbsp;range&nbsp;(i.e. severe&nbsp;accident simulator).&nbsp;However, due to the slow development of severe&nbsp;accident and the real-time characteristic of full scope simulator, the preparation of the drilling&nbsp;script&nbsp;always&nbsp;takes a lot of time.&nbsp;Secondly, during the&nbsp;nuclear emergency drilling, the data of the full scope simulator will be displayed on the screen of&nbsp;the emergency headquarters. Due to the limitation of the simulation scope, the full&nbsp;scope simulator&nbsp;cannot provide the&nbsp;reasonable and effective data under&nbsp;the extension of design, which makes the subsequent drilling&nbsp;lack of data support and the emergency decision lack of theoretical basis.&nbsp;Thirdly, during the emergency drilling, the information displayed on the screen of&nbsp;the emergency headquarters is not enough and is not intuitive enough.&nbsp; &nbsp; &nbsp; &nbsp; Therefore, in order to meet the requirements of the&nbsp;nuclear emergency drilling scripting&nbsp;and the nuclear emergency decision support during the drilling, the study carries out the rapid simulation calculation by using the integrated severe&nbsp;accident analysis program, performs the 3D modeling of nuclear power plant with 3DMax software, and implements the effect&nbsp;rendering with Unity3d.&nbsp;A set of nuclear emergency drilling&nbsp;assistant system has been&nbsp;developed to meet the requirements of nuclear emergency drilling&nbsp;scripting and the decision-making support for&nbsp;emergency drilling&nbsp;in emergency headquarters.&nbsp; &nbsp; &nbsp; &nbsp; The application of the system can effectively reduce the difficulty and workload of nuclear emergency drilling&nbsp;scripting, and improve the efficiency and credibility of the scripting.&nbsp;Additionally, it can vividly present&nbsp;the main phenomena and processes of nuclear accident, and provide the real-time dynamic data under&nbsp;the whole range and all working conditions for nuclear emergency drilling.&nbsp;Meanwhile, it&nbsp;can&nbsp;provide&nbsp;the&nbsp;real-time interaction function to improve the authenticity of the drilling&nbsp;and the ability to deal with emergencies.&nbsp;The development of the system has been strongly supported and affirmed by the nuclear operating units, but its&nbsp;promotion and application need to be fully demonstrated.

2021 28th International Conference on Nuclear Engineering (ICONE28)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
