- W4283074258 abstract "• Conserved physical information neural networks can solve neutron diffusion problems with unsmooth solutions. • A generic construction method is proposed for cPINN to strictly comply with the boundary conditions. • The proposed construction method can improve the performance of cPINN. Application of physics-informed neural network(PINN) on neutron diffusion equation, which is of great engineering significance for reactor physics field, has not received much attention yet. Meanwhile, the non-smoothness of solution for neutron diffusion equation brings difficulties for PINN’s application. Therefore, we introduce the conservative PINN(cPINN) which develops PINN for each sub-domain and considers additional conservation law along the sub-domains’ interfaces, to solve heterogeneous neutron diffusion problems. Specifically, we develop PINNs on each sub-domain which has same material property and set equality constraints for neutron flux and neutron current on adjacent sub-domains. Furthermore, we propose a neural network constructing method to ensure that PINN/cPINN predictions strictly conform to three types of boundary conditions(BCs) involved in neutron diffusion problems. The results of numerical examples demonstrate that cPINN can solve heterogeneous neutron diffusion problems with non-smooth solutions and the proposed BC-imposed method can help to improve the cPINN performance on complex heterogeneous problems." @default.
