Enhancing Nuclear Energy Safety: How Artificial Intelligence is Revolutionizing the Industry?

Introduction

Nuclear energy has become a critical part of the global energy mix, providing reliable, low-carbon electricity to millions of people around the world. However, the nuclear industry is constantly under scrutiny due to the potential safety risks associated with nuclear power plants. The industry has made significant strides in enhancing safety measures, but there is still room for improvement. That is where artificial intelligence (AI) comes in. In this article, I will discuss the role of AI in improving nuclear energy safety and the benefits it brings to the industry.

Introduction to nuclear energy and its importance

Nuclear energy is the energy released by a nuclear reaction, either through nuclear fusion or nuclear fission. Nuclear power plants use nuclear fission to generate electricity. This process involves splitting atoms of uranium in a controlled environment, which creates heat that is used to produce steam and generate electricity. Nuclear energy is a low-carbon source of electricity that does not emit greenhouse gases.

Nuclear energy is a critical part of the energy mix in many countries around the world. According to the International Atomic Energy Agency (IAEA), there are currently 443 nuclear power reactors operating in 30 countries, providing around 10% of the world’s electricity. Nuclear energy is a reliable source of electricity that can operate 24/7, making it an important component of energy security.

Although nuclear energy is a low-carbon source of electricity, it comes with potential safety risks. The nuclear industry has made significant strides in enhancing safety measures since the Chernobyl and Fukushima accidents. However, accidents can still happen, and it is essential to continue improving safety measures to minimize the potential impact of any accidents.

The nuclear industry uses a defense-in-depth approach to safety, which involves multiple layers of protection to prevent accidents and mitigate their consequences. These layers include physical barriers, such as containment structures and fuel cladding, and operational measures, such as safety procedures and training programs. However, these measures are not foolproof, and there is still room for improvement.

Nuclear power plants have traditionally relied on routine preventive maintenance, which can result in excessive maintenance and increased expenses. To increase safety and cost-effectiveness, researchers developed an AI-based Prognostics and Health Management (PHM) framework. This framework estimates equipment’s residual usable life (RUL), allowing for a change from fixed to on-demand maintenance. Maintenance procedures can be optimised by using machine learning algorithms, reducing resource waste and lowering the dangers associated with unnecessary maintenance.

Decision Support Systems: Helping Operators in Unexpected Situations

To improve operator decision-making in nuclear power plants, smart support systems have been intensively investigated. These devices are designed to reduce information overload and operator stress during unexpected conditions. Artificial neural networks (ANNs) and knowledge-based systems aid in the rapid identification of problems and the provision of accident-related information. Deep learning models have demonstrated accuracy in forecasting accidents, and ANNs paired with knowledge-based modules increase fault detection accuracy. Declarative AI methodologies and uncertainty estimation techniques aid in decision-making by decreasing human mistake and operator stress.

Optimising Performance and Safety through Fuel Management

By optimising fuel assembly design, core refill patterns, and fuel performance evaluation, AI has significantly enhanced fuel management in the nuclear sector. AI-based models allow for a thorough examination of fuel qualities and their interdependence, assuring safe and efficient operation. Power plant operators have more options for optimising fuel bundle burnups and calculating discharge burnups by using algorithms such as ant-colony models, genetic algorithms, and particle swarm optimisation.

Operator Monitoring Systems: Improving Safety and Reducing Human Error

AI developments have transformed nuclear power plant operator monitoring systems, drastically lowering human error and increasing safety. Traditional methods of determining an operator’s fitness for duty have been subjective and uncommon. AI-based solutions, such as bio-monitoring systems, facial expression analysis, computer vision technologies, and wearable device sensors, on the other hand, allow for continuous monitoring of operators’ physical and mental performance. These technologies promote situational awareness and team coordination by predicting and mitigating human error risks, monitoring cognitive aspects, simplifying measurement methods, detecting aberrant behavior, and improving situational awareness and team coordination. 

Sensor Fault Detection Systems: Improving Decision-Making

Reliable sensor data is critical for making accurate decisions in nuclear power plants to ensure safety. Sensor failures or inaccurate readings might result in potential risks and improper actions. AI has enhanced sensor defect detection systems in nuclear power plants by identifying and diagnosing instrument faults using probabilistic neural networks, fuzzy logic, and machine learning models. These systems detect and isolate sensor problems by monitoring discrepancies between expected and observed plant parameters.

Using natural language processing (NLP) techniques, AI has enhanced the operation and safety of nuclear power plants by improving safety evaluation processes and automating the interpretation of event data. It has aided in the detection of errors, violations, and procedure concerns, as well as the improvement of team processes and the incorporation of organisational variables into risk assessments, all of which have increased the efficiency of safety analysis. Deep learning and other AI algorithms have produced believable accident scenarios and reduced uncertainty in safety analyses, resulting in more thorough and dynamic safety evaluations.
