Advanced Reactor Passive System Reliability Demonstration Analysis for an External Event

open access: yesNuclear Engineering and Technology, 2017
Many advanced reactor designs rely on passive systems to fulfill safety functions during accident sequences. These systems depend heavily on boundary conditions to induce a motive force, meaning the system can fail to operate as intended because of ...

Passivity Encoding Representations of Nonlinear Systems

open access: yesIEEE Transactions on Automatic Control
Passive systems are characterized by their inability to generate energy internally, providing a powerful tool for modeling physical phenomena. In addition, algebraically encoding passivity in the system description can be advantageous. For this, port-Hamiltonian systems are a prominent approach.
