New JI-PINN method speeds up nuclear reactor analysis with neural networks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called the Joint Initialization Physics-Informed Neural Network (JI-PINN) to improve the efficiency of calculating the effective multiplication factor (keff) in nuclear reactor analysis. This approach uses a low-resolution approximate solution to create a joint initial state for network parameters and keff, which are then optimized under physical constraints. Testing on various benchmark cases demonstrated that JI-PINN reduced computational time by up to 49.4% while maintaining comparable accuracy and decreasing the occurrence of anomalous results. AI

IMPACT This research offers a more efficient and robust method for solving complex physics problems using neural networks, potentially impacting fields requiring high-precision simulations.
