Earthquake response of a core shroud for APR1400
Nuclear Engineering and Technology, 2021 The core shroud is one of the most important internal components of the reactor vessel internals because it meets the neutron fluence directly emitted by the nuclear fuel.

Nuclear heat storage and recovery for the APR1400
Journal of Energy Storage, 2020 Abstract Detailed here is the proposed design of the tertiary side of a Thermal Energy Storage (TES) System to be interfaced with the steam cycle of a Light Water Reactor (LWR) plant. This study extends the understanding provided by many previous investigations (i.e., beyond thermodynamic considerations) by specifically addressing real world ...

Analysis of LBLOCA of APR1400 with 3D RPV model using TRACE
Nuclear Engineering and Technology, 2023 It is very difficult to capture the multi-dimensional phenomena such as asymmetric flow and temperature distributions with the one-dimensional (1D) model, obviously, due to its inherent limitation.
