Containment system based on digital twin technology and design method

Abstract

The invention relates to a digital twinborn technology-based containment system and a design method, a digital twinborn body corresponding to a physical entity containment system is constructed in a virtual space of a computer or a server, and the digital twinborn body comprises a virtual reality simulation module, a mechanics and thermodynamics multi-physics field coupling calculation module, a digital twinborn body model and a digital twinborn body model; a durability and life prediction calculation module, a machine learning prediction calculation module, and an early warning and feedback control module; cognizing and collecting data through a sensor system, a data feedback system and an acquisition system arranged on the physical entity containment to form a cognitive database of the physical entity containment system as a data input source of the digital twin; the digital twinborn body is subjected to analog calculation through each calculation module, information transmission is carried out to each party, information acquisition channels of each party are unblocked, and information exchange channels among the parties are opened, so that the accident coping capability of a nuclear power plant can be better improved, and the nuclear power safety is improved.

Description

technical field [0001] The invention belongs to the nuclear engineering design technology, and specifically relates to a containment system and a design method based on the digital twin technology. Background technique [0002] Nuclear power generation is a clean and efficient energy utilization method. However, due to the special nature of nuclear power, its safety has always been the focus of regulatory authorities and the public. Therefore, in the design of nuclear power plants, the design goal is to substantially eliminate the release of large-scale radioactive substances. At the same time, the design concept of defense in depth is adopted, such as the isolation of radioactive nuclear fuel, three physical barriers are set up, one, the fuel cladding; Third, a containment that can withstand a certain accident pressure and temperature. Among them, the containment shell, as the last physical boundary, plays a crucial role in ensuring nuclear safety. [0003] In the Cherno...

AI Technical Summary

Problems solved by technology

Moreover, in the operating state, some areas in the containment are inaccessible due to high temperature and radiation, which may cause hidden dangers that cannot be discovered in time

For the nuclear regulatory authorities, they mostly obtain information by accepting and reporting, and cannot understand the real-time status

For the emergency and disaster relief parties, if the extreme situations that are designed to deal with, such as aircraft collisions, external terrorist attacks, and hurricanes, etc., the design and operation parties cannot provide real-time mechanical status and damage conditions of the reinforced concrete shell as a whole, which may Waste precious emergency or rescue time, and may also result in poorly targeted emergency plans
